Well....all i gotta say about this one is &@$!*^$%$*&#@.
Anyone else feel the same way?
Im hoping for a very very nice curve...that would be my only hope for an 800 on this test.
By Ella05 (Ella05) on Saturday, June 05, 2004  11:09 am: Edit 
hey, me too! I didn't even do all the problems; I ommitted 9. Oh, let there be a huge curve. It seemed way harder than the practice tests.
By Kewlkiwi102 (Kewlkiwi102) on Saturday, June 05, 2004  11:14 am: Edit 
Omitted 5...I never even had to do that on Barrons.
If I omitted 5 and got 2 wrong what are my odds of getting an 800?
By Aoe2guy (Aoe2guy) on Saturday, June 05, 2004  11:15 am: Edit 
Kiwi if you're sure you only got 2 wrong, and seeing that this test was evidently difficult, i think you're fine
By Kewlkiwi102 (Kewlkiwi102) on Saturday, June 05, 2004  11:21 am: Edit 
I dont know if I only got two wrong. One i am sure of, the other one i threw in there to account for stupidity. Hopefully, the ones I omitted would have been the ones I would have normally gotten wrong any way...hm...
good luck to everyone else out there!
By Chamonix (Chamonix) on Saturday, June 05, 2004  11:45 am: Edit 
I came out feeling good. I omitted 4, and am sure that I got 1 wrong. I omitted the last three (not because of time), and one in the early fourties.
By Bcrichsolo (Bcrichsolo) on Saturday, June 05, 2004  11:46 am: Edit 
i omited 8 and i didnt omit any on barrons....i was so frusterated when she called time
By Bcrichsolo (Bcrichsolo) on Saturday, June 05, 2004  11:46 am: Edit 
wats the usual curve?
By Chamonix (Chamonix) on Saturday, June 05, 2004  11:48 am: Edit 
In the real SAT II's its:
43 raw score= 800
38= 750
33=700
By Whirlziggi (Whirlziggi) on Saturday, June 05, 2004  12:02 pm: Edit 
Omg.. I'm so scared. I omitted 8, and i dont even know how many careless mistakes i might have made.. and i cant cancel it, because i think i did well on the chem Aarghh.. we should all collectively pray for a huge curve. I thought that test was so hard, the sad thing is i couldve done the probs but i ran out of time!!
By Bcrichsolo (Bcrichsolo) on Saturday, June 05, 2004  12:03 pm: Edit 
I left 8 blank and guessed 2 about 2. Im pretty sure I got the rest right so I hope I got 750
By Kewlkiwi102 (Kewlkiwi102) on Saturday, June 05, 2004  12:04 pm: Edit 
Exactly. Time was the issue for me also.
By Bcrichsolo (Bcrichsolo) on Saturday, June 05, 2004  12:06 pm: Edit 
yea i agree with whirl. Some of the questions at the end were very hard and I just locked up...The only problem was... The begining was very easy compared to other tests. After 40 every problem was hard I think so the curve is probably gona be pretty decent
By Goonberg (Goonberg) on Saturday, June 05, 2004  12:13 pm: Edit 
Did anyone else feel like secant was involved in every other problem? I just thought that was strange, maybe looking for a little more variety. It seemed easy as to what I was expecting. My only problem was that I could have used a little more time to finish 49 and 50, which I had to omit, and to go back over the test. I omitted about 6 in total, maybe missed 3, hoping for mid 700s.
By Npatrick6 (Npatrick6) on Saturday, June 05, 2004  12:17 pm: Edit 
I had an 800M on my SAT I and got an 800 on the Real SAT IIs test last night.
Today... $#&*(#$@#@$%
The first part of the test was really easy, pretty sure I aced it up to about question 42. I had about 10 minutes left at this point. What a big mistake. The last few problems I found to be extremely hard.
And then I started to panic.
So, in the end, I omitted 6 or 7 and most likely got 2 or 3 wrong.
I really want that 800... not sure if I should cancel, cause then I'd have to cancel my writing score also (which I did decent on, I guess).
Please let there be a huge curve........
By Frenchfries (Frenchfries) on Saturday, June 05, 2004  12:17 pm: Edit 
On the three Barron's tests I took (timed), I never got to the last 10 or so, plus I always skipped about 5 on top of that and got around 7 wrong. Even on the two Sparknotes tests I took, I still couldn't finish, even though I did a lot better than Barron's. But the test today? I zoomed right through the first half easily in 20 minutes (highly abnormal), and until the last 10, skipping a problem because I couldn't figure it out didn't even cross my mind. I was really nervous coming in, but now that I'm finished, I feel confident. Phew. I skipped three problems altogether: 44, 45, and one other one that was either 47, 48 or 49.

i thought it was like a million times easier than the barrons book, i didnt omit and on barrons i omitted at least 5 on the 3 practice tests i took. The only annoying question was the one with the line thats slicing the rectangle and the last one with the cone,those took a while to do, otherwise most were straight forward
By Hermione (Hermione) on Saturday, June 05, 2004  12:23 pm: Edit 
Is the scaled score chart a set thing, or they do they curve it more depending on how the majority of people do?

The latter.
By Shaka (Shaka) on Saturday, June 05, 2004  12:25 pm: Edit 
OMG i omitted 5 and i made at least one STUPID mistake that i know of!!!
i was so stupid, for the question about the line reflecting the pts...i put 0,0!! SO STUPID OMFG
and YES, the last few questions take too long to do so i skipped
By Katiya (Katiya) on Saturday, June 05, 2004  12:26 pm: Edit 
what does F(x1) F(x1) mean??
By Shaka (Shaka) on Saturday, June 05, 2004  12:27 pm: Edit 
yea, katiya, i skipped that one
anyone remember those 2 probability/permutation/combination questions? one was about three types of..someting...i think it should be 5 * 4 * 3?
the other was like.... 7/18 times 6/17?
right?
By Cognitio (Cognitio) on Saturday, June 05, 2004  12:28 pm: Edit 
It depends what F(x) is, you need to evaluate each function and then multiply what you get... If F(x) = x, then the answer would be x^22x+1, etc.
By Vladimir2004 (Vladimir2004) on Saturday, June 05, 2004  12:28 pm: Edit 
Let me tell you guys something: The test starts, I answer the first say 25 questions without problems, and think to myself: damn, I'm getting a 800 on this. So, i relax and take my time which i should not have done. I get stuck on a couple of problems, and after i figure them out i realize that there are like 20 more questions and 10 minutes left! I ommites like 8 or 10, and let's assume i got 5 wrong, do i have a chance for a 700? I'm so frustrated, because i think they purposely made this test to screw us over. In fact, it was pretty easy tho.
By Shaka (Shaka) on Saturday, June 05, 2004  12:29 pm: Edit 
vlad, you are like reading my mind...i was like that too...AND THERE WAS THIS HOT GRL SITTIN ACROSS FROM ME OMG...she kept dustin off her tanktop and i was like *droolz
By Chamonix (Chamonix) on Saturday, June 05, 2004  12:38 pm: Edit 
Shaka: for the probablity one your right on the 7/18*6/17, but on the other wasn't it 4*3*2, at least that's what I put.
the sliced rectable one was 1
does anyone remember the two spheres intersecting and the determinate of a matrix one?
By Shaka (Shaka) on Saturday, June 05, 2004  12:39 pm: Edit 
yea, chamonix, i mustve remember the #s wrong...your right
By Katiya (Katiya) on Saturday, June 05, 2004  12:40 pm: Edit 
Shaka  i got those also
Cognitio  i don't know what you are saying...
i think i wrote it wrong before, i was something like F(x) = (x1) F (x1) then it said that F(.21) = 4.256 .... i made up those numbers though, all i remember is that they were decimals. I thought that it was ...recursive? is that the word, but it wasn't and then I had already spent to much time on it so I stopped thinking about it.
Vladimiromfg the same thing happened to me, I was going pretty fast in the beginning, with 20 minutes left I had a little more than 10 problems left... and somehow I only had time to do like 5 of them and I left 7 or so blank in total. In the beginning they were easy so I was doublechecking myself. ARGH! I should have done the test backwards.
By Maud (Maud) on Saturday, June 05, 2004  12:43 pm: Edit 
hey what about the last problem with the cone...what was the height? im slow...it took me forever to get that, and then i just gave up and guessed A
Also, what about the one with two spheres of different diameters intersecting?
AHHH that test killed me!
By Shaka (Shaka) on Saturday, June 05, 2004  12:44 pm: Edit 
OHHH the angles of those 2 lines...slope 2/5 and slope 3/5...was it like...9.16 degrees or soetmhing?
By Adjlad (Adjlad) on Saturday, June 05, 2004  12:44 pm: Edit 
damn, me too
the ones in the beginning were so easy that i lost that sense of urgency
voila>
8 questions blank
a couple o' guesses
By Chamonix (Chamonix) on Saturday, June 05, 2004  12:45 pm: Edit 
Katiya: that's exactly how the question read except your numbers on the right are made up (I don't remember what they are). So how do you do it. I entered in the numbers but my answer wasn't one of the answers, so I left it blank.
By Cognitio (Cognitio) on Saturday, June 05, 2004  12:45 pm: Edit 
Ah okay, yeah, any function that equals an expression involving itself is recursive.
I'm not sure how to solve it when you have an input like that. I do remember, though, solving a repeated fraction that was like 1 + 1/(1 + 1/(1 + 1/(1 + 1/... = ?, that went on forever. You had to model it as x = 1 + 1/x, then you can solve it as a quadratic. This would work if you could substitute y for f(x), but unfortunately you can't since you have a strange input...or something.
By Chamonix (Chamonix) on Saturday, June 05, 2004  12:46 pm: Edit 
Shaka: I got 9.16 too, I'm pretty sure that's right.
By Shaka (Shaka) on Saturday, June 05, 2004  12:47 pm: Edit 
yay, i kinda guessed on that...i tried using law of cosines...but i think the answer wasnt exactly the same...
By Chamonix (Chamonix) on Saturday, June 05, 2004  12:48 pm: Edit 
Did you guys get 0 for the determinate of that matrix?
By Maud (Maud) on Saturday, June 05, 2004  12:50 pm: Edit 
yeah i got 0...just plug it in the calc
what about the second to last one, something with m raised to like 91 and 90...
By Chamonix (Chamonix) on Saturday, June 05, 2004  12:52 pm: Edit 
wohooo, that was one of the ones I wasn't sure of. I knew how to do the second to last one, but it would have taken too long.
For the intersection of the two spheres surfaces, was the answer a circle and a point.
I hate the those ones, I said a sphere and a point, but I'm pretty sure that's wrong.
By Ragnarok (Ragnarok) on Saturday, June 05, 2004  12:53 pm: Edit 
I'm not sure if I should cancel or not... What is a college's usual policy about taking the SAT IIs more than once, do they look at the highest score?
I had the same problem as a lot of other people, the beginning was easy so for some reason I thought to myself, 'Hmm, it's easy, let me take my time and check over all of my answers to make sure I don't make any stupid mistakes on these easy ones.' And then, of course, I didn't get even close to finishing. I'm thinking about canceling, but I'm not sure if I should since I think I did pretty good on the writing test.
By Maud (Maud) on Saturday, June 05, 2004  12:54 pm: Edit 
i put circle and point but that was random last minute guess
what about the last one? did anyone get it?
By Katiya (Katiya) on Saturday, June 05, 2004  12:55 pm: Edit 
hell yea, that determinant one was so pleasing. i had like 3 minutes left and a lot of questions left so i just skimmed over them and was like, yay determinant of a 3x3 matrix... aka, do you kno how to use your calculator???
I got the 9.16 one too, using the difference of the inverse tan of 2/5 and 3/5
the F(x) question is still bothering me...
By Chamonix (Chamonix) on Saturday, June 05, 2004  12:55 pm: Edit 
I'm pretty sure it was circle and a point.
By Hermione (Hermione) on Saturday, June 05, 2004  12:57 pm: Edit 
How would they make a circle? *worried*
By Chamonix (Chamonix) on Saturday, June 05, 2004  12:57 pm: Edit 
well, I just entered it into the calculator, but I don't even know what a determinant is.
cool
By Hewashere (Hewashere) on Saturday, June 05, 2004  12:59 pm: Edit 
can anyone explain to me why the sliced rectangle one was 1?
wat was theanswer for the vector problem?
did anyone get 14.92 for the last one with the height ofthe smaller cone?
By Zas1987 (Zas1987) on Saturday, June 05, 2004  01:00 pm: Edit 
why would there be a circle AND a point? if they intersect, there would only be a circle... right? if they are tangent, THEN there would be a point.
By Chamonix (Chamonix) on Saturday, June 05, 2004  01:01 pm: Edit 
I didn't even say that, so I hope that's wrong. But if what I remember is correct, it was the interesection of the two spheres surfaces, the key word being surfaces. Am I correct in remember the word surfaces, because if that was the word, then just think about it, the surfaces intersection make a circle. Use your hands as the two spheres and join them together.
By Maud (Maud) on Saturday, June 05, 2004  01:03 pm: Edit 
for the sliced rectangle, if you put the points in to the calculator and graph all the lines, you can see that the y = x1 line cuts it in half...not exactly into two triangles but into like 2 trapezoid things that look about the same
even if you can't tell that they were the same you could see that the other lines are way off, and 1 is the closest
I got 8.32 for the height but I bet that's wrong because i had no clue what I was doing..i tried to use ratios and stuff to find the radius but then I got 9,which seemed too easy,so I picked the closest answer choice to 9, which was A
oh well...
By Monoe (Monoe) on Saturday, June 05, 2004  01:05 pm: Edit 
I thought it was the best testing I've ever done. I am hoping for an 800. I omitted 3 and doubt I got more than 2 or 3 others wrong.
How would one figure out the 90 and 91 exponent one? How would two spheres intersect?
Those were two of the three I omitted  I believe the other one was a time issue  I could do it, but it would take too much time.
Overall, if the curve is as nice as you all are hoping, I should expect high 700's at least.
By Katiya (Katiya) on Saturday, June 05, 2004  01:06 pm: Edit 
Oh no.
I think I got the sphere one wrong, because a sphere is just the outside, isn't it? So they wouldn't intersect for the whole thing because they have different diameters. So, a point or a circle. *stupid me*
By Chamonix (Chamonix) on Saturday, June 05, 2004  01:06 pm: Edit 
maybe it's just a circle, I'm not sure.
For those of you who used the Barron's book, did you enter in the formulas into your calculator that they gave. Because one of them was finding the acute angle one. When I saw that problem, I was just amazed because I had no idea how to do it, but I still got the answer right because of the program. Thank you Barron's.
By Chamonix (Chamonix) on Saturday, June 05, 2004  01:08 pm: Edit 
Katiya: I did the exact same thing. bummer
By Maud (Maud) on Saturday, June 05, 2004  01:08 pm: Edit 
what were the answer choices for the sphere one again?
was there some choice with "or" and another with "and"...i dont remember i came back to that one and then I just guessed, i didn't read carefully enough so I don't remember now
By Monoe (Monoe) on Saturday, June 05, 2004  01:11 pm: Edit 
I am starting to think that the answer should be 'a circle only'...but I don't remember if that was a choice. I think that it wasn't, and that's why I didn't answer it.
By Impatheticiknow (Impatheticiknow) on Saturday, June 05, 2004  01:11 pm: Edit 
circle and point is what i put...some others i remember putting...aplitude is 5, i think that vector one was D, 1001 was the first term, the limit one was 2, domian for one was 0<or eq. to x<oreq 4, f(x)f(3)=f(x+3) was e^x, smallest triangle angle was somewhere in the 40s (i think), sin B=1/4, (1,0) for the point, y=x5 for the +c one, x cannot be sometingpi, point on a circle is (1,2)..
By Kewlkiwi102 (Kewlkiwi102) on Saturday, June 05, 2004  01:11 pm: Edit 
Its a point and a circle. The point would be if they were tangent which still counts as an intersection.
It cannot be a sphere i think....I cant even vizualize how that would happen
What was witht he F(x)=(x1)F(x1) question? I looked at it, and said im not wasting my time.
What was with the rectangle? None of those would work I thought becuase the line was y=xc, and the point was (4,6) so to make congurent shapes out of it it would have to cut through the diagonal, or straigh across or straigh up and down through the middle. What did i miss there?
The angle one was 9 something
Um um um....what was #47?
By Haruhara (Haruhara) on Saturday, June 05, 2004  01:12 pm: Edit 
0 for the determinant of the matrix?
point OR circle... not sure if there had been a point AND circle choice
By Maud (Maud) on Saturday, June 05, 2004  01:13 pm: Edit 
doesnt amplitude have to be positive? i put 5 for that...but maybe im just mixed up
i got 44 for the smallest angle one, and e^x also (i think that was the third to last question right?)
By Adjlad (Adjlad) on Saturday, June 05, 2004  01:14 pm: Edit 
amplitude one was +5
no such thing as negative amplitude

By Meekchun (Meekchun) on Saturday, June 05, 2004  01:16 pm: Edit 
in the x+c question .. c was 1 right? because it made like two identical trapezoid thingys?
By Homer2568 (Homer2568) on Saturday, June 05, 2004  01:17 pm: Edit 
just to let you all know...the angle between the two lines was 9.16...barrons iic book has a program they tell u to put on ur calculator that does that exact problem

yes
By Xbizkitl (Xbizkitl) on Saturday, June 05, 2004  01:18 pm: Edit 
No. What doesn't get flipped when you reflect something? Only some point that's on the line.
It was 8,17.
By Maud (Maud) on Saturday, June 05, 2004  01:18 pm: Edit 
Meekchun  I got that too
the line was x+c right, not xc?
Monoe i got origin also...it seemed too easy but i didnt feel like wasting time checking to see if it was right...
By Meekchun (Meekchun) on Saturday, June 05, 2004  01:19 pm: Edit 
yea (8,17) was right  it was on the line

i marked B
neone else

so it specified 2 trapezoids?
By Meekchun (Meekchun) on Saturday, June 05, 2004  01:29 pm: Edit

would any of those have had a mode?
By Hewashere (Hewashere) on Saturday, June 05, 2004  01:42 pm: Edit 
did anyone get 14.92 for the last one?
By Monoe (Monoe) on Saturday, June 05, 2004  01:42 pm: Edit 
none would have a mode, and the mean can't be even because it ends in '.5'
For the last question, I worked it out and am quite sure I got it right, but I forget what I put. It was NOT 9 or 8.whatever. It was D or E.

By Hewashere (Hewashere) on Saturday, June 05, 2004  01:50 pm: Edit 
i still don't understand why anyone would want to divide a rectangle into two trapezoids instead of two right triangles when the latter is much easier. btw, how would u know for certain that the two trapezoids are, in fact, congruent other than eyeballing it?

By Zas1987 (Zas1987) on Saturday, June 05, 2004  01:54 pm: Edit 
for teh last one i definitely got 9... the radius stayed the same so you just had to divide the volume by two, and solve for the new height, right? i got 9....
By Aceofhearts54 (Aceofhearts54) on Saturday, June 05, 2004  01:54 pm: Edit 
Ugh, time was a huge problem, I ended up omitting 7, should have been like 4... And I already know of 1 stupid mistake, probably 2.
9.16 for the 2 slope problems is right I think, tan^1 = angle of inclination, find both and subtract them.
Is a tangent point really considered an "intersection"? If so, I'm pissed.

Eh, I think 42 would be the most we can hope for. 41 would reeeeeeaaaallly be strecthing it. Looking at it now these problems (except for a couple) were not actually that difficult.

F(x) = (x1) F(x1) ... Are you sure thats the exact problem, because I don't remember. ok, It told you one of the parts in the added information. And you had to realize that it was x1 I think and plug it into the other function, or something like that.
ahhh... I'm almost positive I got it right, but I can't remember the problem well.
By Lildude_Ravi (Lildude_Ravi) on Saturday, June 05, 2004  02:00 pm: Edit 
katiya ... we had to calculate f(1.4)
so f(1.4)=(1.41)f(1.41)=0.4*f(0.4)
and we were given the value of f(0.4)....
i dont remember the exact answer

By Goonberg (Goonberg) on Saturday, June 05, 2004  02:05 pm: Edit 
I can talk about F(x) = (x1) F (x1)...they gave you F(.4)=2.7 and then said solve for F(1.4). so it would be (1.4  1)=.4 times F(1.41) which is the same as F(.4) which we know equals 2.7, so the answer is .4 times 2.7, 1.08 was the answer
By Frenchfries (Frenchfries) on Saturday, June 05, 2004  02:06 pm: Edit 
I'm going to try to explain #50...forgive me if I'm wrong or I'm remembering the wrong numbers. The key was (to me, at least) knowing that in cones, the height is always directly proportional to the radius. In this case it, was 18:12, so the radius was 2/3 of the height. The volume of the original cone was 864*Pi (12^2 x 18 x Pi x 1/3). If the volume of the smaller cone was half of that, then it was 432*Pi.
432*Pi=(1/3)Pi*r^2*h, where r is radius and h is height
Then, replace r with (2/3)h
432*Pi=(1/3)Pi*(2h/3)^2*h
432*Pi=(1/3)Pi*(4/9)*h^3
solve for h, answer is 14.29. Someone keeps saying it's 14.92, so hopefully their memory switched the numbers 9 and 2, and both of us got the problem right.

Wow, you guys really thought it was hard? well anyways, i omited none, guessed on none.... some answers... F(x)=(x1)F(x1) they ask for F(1.4) giving us that F(.4)=something SO  (1.41)times F(.4)<they gave you F(.4), so just mulitply that by (1.41)
ummmm, the cone was 14 something
amplitude was 5
the vector b minus vector a was a vector pointing into the third quadrant... I believe the answwr choice was C

i concur with athlon on both of those.
on another note: i still don't understand why anyone would want to divide a rectangle into two trapezoids instead of two right triangles when the latter is much easier. btw, how would u know for certain that the two trapezoids are, in fact, congruent other than eyeballing it?
By Jerseykid (Jerseykid) on Saturday, June 05, 2004  02:15 pm: Edit 
For the sphere question:
I don't remember if the word "surface" was included or not, put two spheres can definitely intersect at only one point, and when they move closer to each other they make a circle.
But the question also said that the spheres have different diameters, so I think that the smaller sphere could be placed entirely inside the larger one, touching it at one point.
So I put all three
By Goonberg (Goonberg) on Saturday, June 05, 2004  02:15 pm: Edit 
same here Whirl, so I ended up skipping it due to time. it's strange because earlier in the year I could do those problems easily. I think my problem was that I was trying to use sine and cosine, forgetting to ever use tangent.
By Kewlkiwi102 (Kewlkiwi102) on Saturday, June 05, 2004  02:15 pm: Edit 
yeah, i got 41 for the surveyor also. wasted so much time on that one.
By Kewlkiwi102 (Kewlkiwi102) on Saturday, June 05, 2004  02:17 pm: Edit 
jersey kid, but thats not an intersection, becuase a sphere is just th epoints on the outside, not all the points on the inside.
I still think point or circle.

Has anyone figured out the answer to the second to last (49). I didn't end up getting an answer I separated them into like terms, and got it to 2m(m^90), but I had no clue where to go from there. Initially, I thought it would be a simple plug into the calculator, only to find out the numbers were too huge. Any comments would be great.

Arrgh i was thinking of putting that.. but I kept getting 42.. so i thought i was doing something wrong, so i left it blank. Also, what was the answer to the one with the cube, and the diagonal makes an angle of 30 degrees, and width was 3, and length was 4 i think, and we had to find the height?
By Monoe (Monoe) on Saturday, June 05, 2004  02:22 pm: Edit 
I got 71something for the surveyor and I think I am right...I equated the two TAN functions for the two triangles created. Anyone back me up?

moneo: I also got 71 and I agree with you on the vector
By Goonberg (Goonberg) on Saturday, June 05, 2004  02:26 pm: Edit 
For the cube and the triangle, I used law of sines to find the side. And I think I ended up getting around 2.88 for the height. then just multiply 4*3*2.88 to get the volume
By Monoe (Monoe) on Saturday, June 05, 2004  02:28 pm: Edit 
On the vector question, plugging in ballpark coordinates eliminates all other choices.
The cube's volume is 2.5 x 4 x 3. 2.5 is the height because of the 306090 triangle formed from the diagonal.

By Aceofhearts54 (Aceofhearts54) on Saturday, June 05, 2004  02:29 pm: Edit 
diagonal in the cube... I figured that the diagonal on the bottom surface was 5, pyth. theorem. Then did tan30 = x/5, x=2.89 Thats the height, but I thought the question was volume? In that case its 2x4x2.89
Anyone else do that?

But wow, what a crazy test! I didn't even get to Nos. 4650, and left 3 others blank. I'm hoping for at least a 700; I think it is obtainable. The first 25 questions I finished in 20 minutes though, and I couldn't even answer 20 more in the next 40. Really weird.
The transformation answer was f(x1)+1.

Hey Caddyshack, your method assumes that the cliff is divided into two parts : X and X + 30, when in fact those are the divisions of the GROUND the surveyor is walking on. He moved 30 feet closer to the cliff. I saw it as X (the original distance from him to the cliff) and X  30 (the distance after he moved 30).
I still think it was 71, I felt good on that one.

People who still think the surveyor one is 71, STOP BEING SO RETARDED AND DO THE PROBLEM AGAIN. First, draw it out, you have two triangles, one with degree measures of 15 [30ft side across from it, 145, and 30. Do a law of sines (sin15)/30=sin30/x. After some simple arithmetic you get 57.96 [make sure youre in degrees mode kids!]. Ok now we have a triangle with a hyp of 57.96 and an angle of 45. Do sin45=x/57.96. You get 41.

m*m^90+2m^90
m^90(2+m)
The m to the 90th power will be an integer, 90/2=45. For the whole thing to be the square of a number, the 2+m gotta be a number you can rad out perfectly, which is 34, E.

By Flameball63 (Flameball63) on Saturday, June 05, 2004  05:06 pm: Edit 
I figured the smaller angle thing...ergh...a little bit too late.
Without the formula:
m1=2/5
m2=3/5
Use the point 0,0.
y1=2/5x
y2=3/5x
use x=5.
You get (5,2) and (5,3)
use the distance formula from (0,0) to the two points: you get: rad 29 and rad 34
from the points, you can tell that they are one unit apart.
So, you have the two lengths of rad 29 and rad 34 and the opposite as 1.
Then, you use the a^2=b^2+c^22*b*c*CosA to figure out A.
And you get 9.16.

what about the one where it was the didtance between 2 points in a 3 coordinate plane? I put 5, is that right?
By Madd87 (Madd87) on Saturday, June 05, 2004  05:43 pm: Edit 
For the splitting one:
If you draw a diagonal, the slope is not 1, so that rules out 0 and a triangle split, so you want to go for two even trapazoids. all the positive numbers make the top half way to small and 5 makes the top half too big. 1 is the only one that fit.
By Madd87 (Madd87) on Saturday, June 05, 2004  05:45 pm: Edit 
Mooses yes I think 5 was right, its sqrt((x1x2)^2 + (y1y2)^2) .. the z coordinates where the same so (z1z2)^2 is 0.
By Madd87 (Madd87) on Saturday, June 05, 2004  05:46 pm: Edit 
Yes I got 25 for the minimum number of whatever.. I remember that one now. I got 24 for some permutations one.

It was some forumla it gave you, it asked about cooling something to 32 or so, all I did was plug the answers in the formula and 25 worked.
By Tamy02 (Tamy02) on Saturday, June 05, 2004  05:49 pm: Edit 
How could it be 25, cuse with 24, you would also get slightly above the number..i remeber i checked that question with both those numbers!
IU think i put 5 but the 3 point cordinate question!

wow. i really thought the test was easy. i left two blank and probably got all others correct; it may turn out that i miss one because of a careless mistake.
so, IMPORTANT question:
what would you think about a person that has an 800 on Math IIc but always seems to make careless mistakes on the SAT and scores a 750? do MOST people who score an 800 on IIc have an 800 on the regular section?
thanks bunches!

The test was much easier than Barrons practice tests although i omitted four and probably got 2 or 3 wrong. hopefully thats enough for 800.
What was the ice cube question?
By Scion (Scion) on Sunday, June 06, 2004  12:27 am: Edit 
ok, for the ice cubes, I got 25, but some got 24. and for number 48, i thought it was f(x)=log x, cuz a property of log is f(x+3)= f(x)f(3), right? o i dont know...
By Kingkonglives (Kingkonglives) on Sunday, June 06, 2004  12:29 am: Edit 
uhh is omitting 5 bad? i didn't study at all, and that's what i did... it really wasn't that hard, if i studied i wouldn't have gotten any wrong... the point about the first half being easy as hell and putting us in a sense of security is def. true
for the function problems i was just like wtf?? oh well

for number 48 i put log x too but i think its wrong.
log(x+3) does not equal log(x)*log(3)

What is the lowest raw score thats possible for a 730? Anyone know?
By Irock1ce (Irock1ce) on Sunday, June 06, 2004  01:14 am: Edit 
the question about which one is f(x)f(3) is e^x. Think about it, e^(x+y) = (e^x)(e^y). However, it also said that it must be all real numbers (i think), and e^x is the only one that fulfils that for log(x+3) = log(3x) = log3/logx. So therefore, e^x is the correct answer. Also, one of my really really really smart friends (1600,800,800 so far) got e^x as well.

oh my,,,
math iic was difficult, i didn;t study at all!
oh well...I hope i got over 700, that would be amazing! I would be sooo happy if I got like a 720, or 710 even! or even 700!!
I haven;t taken any practice tests so I don;t know whether this was abnormally hard or easy...it was hard for me! it was so much harder than the IB math test!!

damn yo.....id like to think of myself as one of the top kids at math (not in the nation or nything, jus in general).....but that was a weird test....i breezed through most of it....i had 35 done with 20 min to go.....easy? NO....i skipped 5 in those last 15 questions....time was an issue....each of the last set of problems looked like it would take soo long, so i decided to omit them and jus make sure i did the others at the end correctly.....i omitted 5 and probably got 14 stupid ones wrong (carelessness)....do you think thats enough for an 800?

Would a 41.5 raw (that's my estimate) have any chance at being an 800 if the curve is large? Would that round up to 42 raw?

By Modestmouse (Modestmouse) on Sunday, June 06, 2004  12:16 pm: Edit 
Npatrick6, yup that's an 800... 42 in 22 Reals is an 800.
Okay, Missgrapes. 8 omits... 2 wrong.
40(2/4)= 39.5, or a raw of 40...
In 22 Reals that is a 770... You're pretty much set for 750+, don't sweat it...

I really hope they have a differnet test (Not differnet because they're LD, but differnet because you're all talking about the answers!!!) Can someone explain this???? Or is this a (do I dare say) ILLEGAL discussion...
By Cmu86 (Cmu86) on Sunday, June 06, 2004  12:28 pm: Edit 
intersection between two spheres can be a point and a sphere
When smaller sphere is inside the larger sphere, intersection is sphere
When two spheres are tangent, a point is intersection.
When two spheres cross each other, the shape of intersection is like... a football(?)
point and circle will be right if they are talking about empty spheres... but i don't think they were talking about empty spheres
Everyone agree?
By Madd87 (Madd87) on Sunday, June 06, 2004  01:14 pm: Edit 
No, I'm pretty sure it is a point and a circle. When one is inside the other it's not an intersection.
By Sirhcv (Sirhcv) on Sunday, June 06, 2004  01:19 pm: Edit 
A sphere is "empty" as you say... A sphere is defined is a 3dimensional surface, all points of which are equidistant from a fixed point. So the intersection will either be a point OR circle, they cannot intersect to form a point AND a circle, it must be one or the other... Now that thats cleared up, can someone answer my question?!?! =)
By Satchamp (Satchamp) on Sunday, June 06, 2004  01:54 pm: Edit 
i put POINT OR A SPHERE,.......i used my hands as spheres and made them cross into each other.....
u get a 3D intersection if u do that.......
how can 3D objects inbtersect to form a 2D shape.....
By Sirhcv (Sirhcv) on Sunday, June 06, 2004  02:04 pm: Edit 
arg!!! its quite simple, think of a sphere as "hollow", its infinitly thin. And even if you did think of a sphere as solid, intersecting them would give you a flying saucer looking thing (I'm not sure of the name) not a sphere. Its a 2D shape but in 3 dimensions, if you dont believe me thats fine...
Now can someone that knows clarify why its ok to talk about this when some people havent taken the exam?
By Lahlahlah (Lahlahlah) on Sunday, June 06, 2004  02:06 pm: Edit 
how do you get a circle anyone?
By Pyro (Pyro) on Sunday, June 06, 2004  02:13 pm: Edit 
damn question about m^91 + 2m^90... solution is blindingly obvious now but i completely blanked during the test.
By Pyro (Pyro) on Sunday, June 06, 2004  02:29 pm: Edit 
some people asked above how you get the angle between the lines passing through (2,5) and (3,5). Treat them as the vectors and , then use the formula cosA = u.v/uv, and take the arcosine
also, about the m^91 problem:
m^91 + 2m^90 = m^90( m + 2), so sqrt(m^90( m + 2)) = m^45*sqrt(m + 2). Then you just find the value given that makes m+2 a perfect square.
and about the problem where f(x) = (x1)f(x1) (IIRC). They want you to find f(1.4), and f(0.4) is given, so it's pretty easy if you keep that in mind.
By Shaka (Shaka) on Sunday, June 06, 2004  02:39 pm: Edit 
CIRCLE AND POINT IS RIGHT
CIRCLE is WHERE the 2 SPHEREs intersect, NOT what they MAKE!
By Npatrick6 (Npatrick6) on Sunday, June 06, 2004  03:06 pm: Edit 
Thanks Modestmouse.
And yeah, what Shaka said. No more need to argue. Circle and point IS the answer. I'd bet a hundred bucks on it.

ya well a sphere within a sphere is an intersection despite what many of you are saying...
its just like a small line segment coinciding with a larger line segment...
By Shaka (Shaka) on Sunday, June 06, 2004  08:32 pm: Edit 
that's a union, not an intersection
By Madd87 (Madd87) on Sunday, June 06, 2004  08:37 pm: Edit

I got a new question. What is the point of taking SAT II (Im not saying this sarcastically) if you are not going to do math? I am confused, cause lots of my friends who want to go into writing/lib arts are taking only History, Writing, and then some easier thing. I want to go into business/polsci/law and am better at history. Was it stupid for me to take the IIC or will it look better to admit Gods than a History? I dont think i crashed and burned on it (by what u guyz are saying, skipped one, missed one), but am debating whether to take more tests in October to show I can be half decent at other stuff as well.
Thanks, you guys really seem intelligent (once again, said with sincerity).

bummer, imma get like 700 on this test. I omitted three but got many many wrong...oh by the way, can someone explain why the next smallest int prob (after 1000) is 1001. I got 1004 because the formula is a(n)=4+(n1)5. If you plug in n=200, the answer is 999. Then you would add five to the net term, 1004. Anyone agree?
And about the vector problem some you say the answer is (4,6) in the fourth quad. But guys isn't (4,6) in the third quad??
By Foundnemo (Foundnemo) on Sunday, June 06, 2004  11:15 pm: Edit 
I took writing and math yesterday. I thought I did pretty well in writing, but math owned me (I should've taken it last year @#@#^$&^# after precal, instead of this year after calc, and I didn't review, yada yada, a lot of excuses which ends in me being stupid and horrible at math in the first place) and I omitted 9. I canceled my both of my scores, even though I was pretty sure that I got everything else right, because I was scared. Now I kind of regret it.
Does anyone know why college board makes you cancel both, and doesn't let you cancel just one score?
Was the answer to the ice cube question 25 or 24?

By Sandwraith (Sandwraith) on Sunday, June 06, 2004  11:33 pm: Edit 
for the rectangle one: someone keeps asking why not just split it into two congruent triangles. the reason you couldn't do that is they told you the equation of the line to split it was y=x+c. If you had been given y=ax then you could have manipulated the slope to have it pass through the diagonal. As it was, you had to determine the correct yintercept. Here's the noneyeballing it way:

b(6,4) first, choose two
```````/````` points a and b where
``````/`````` they are (a,0) and
`````/``````` (b,4)
a
know that rise over run gives slope, we can deduce:
4
 = 1 so 4 = b  a
(ba)
and the fact that any line cutting a rectangle in half has to pass through the center (3,2) tells us that
(a+b)
 = 3 so a + b = 6
2
now we solve
4 = b  a
b = 4 + a
a + b = 6
a + (4 + a) = 6
2a + 4 = 6
2a = 2
a = 1
so point a is at (1,0)
if y = x + c
0 = 1 + c
c = 1
tada! answer ^.^

if they had the same diameter then they can intersect in a sphere since they can be at the exact same place analogous to 2 lines intersecting in a line

ok...look at a definition of intersection:
The point or locus of points where one line, surface, or solid crosses another.
HMM...a POINT or a SURFACE, or a SOLID...
WE have a POINT...we have a CIRCLE (surface)...and SOLIDS do not intersect since they are diff diameters...
CASE CLOSED

im sorry but why cant solids intersect if they have different diameters?

ok...download a 3D cad program...make 2 diff sized spheres...when you put the smaller one into the big one, do they actually INTERSECT? at anywhere? if so, can you give me a point? you can't because there is none...the spheres NEVER touch...
it's the surface that counts, because that's what the coordinates measure...not the space the sphere occupies

bummer, imma get like 700 on this test. I omitted three but got many many wrong...oh by the way, can someone explain why the next smallest int prob (after 1000) is 1001. I got 1004 because the formula is a(n)=4+(n1)5. If you plug in n=200, the answer is 999. Then you would add five to the net term, 1004. Anyone agree?
And about the vector problem some you say the answer is (4,6) in the fourth quad. But guys isn't (4,6) in the third quad??

hold on, there were two answer choices with circle/point? I thought there was one and it was circle OR point. Wouldn't circle AND point be wrong anyway?
By Shaka (Shaka) on Monday, June 07, 2004  07:41 pm: Edit 
ok...it's circle OR point...typo

Don't get so uppity guys, you did a bad job of exlpaining it anyway.

yo fellows, what is a 40 raw?

Will someone please tell me the question number of the one that asked for the intersection of two lines with slopes 2/5 and 3/5? Thank you.

Yeah what is a 40 raw? That would help a lot, thanks.
