<p>im pretty sure the answer was the one posted.</p>
<p>Yeah i did that one. I am almost positive that the answer was D. I worked on it for quite some time.</p>
<p>i think the answer was (x-2)^2+(y+2)^2=4</p>
<p>I think I had what mitpropect has, but both of these answers work, I think, so they werent both choices. I think the one with the two 2s (mit’s) was the answer, but I’m not positive.</p>
<p>I am sorry. I am not entirely sure if the 2 was there. Now that I think about it, it may have been a 1. All I remember was that it was the fourth choice, letter D.</p>
<p>Do you remember what letter you put?</p>
<p>I remember there were a couple of f(g(x)) questions but they were pretty simple, all you had to do was use your calculator.</p>
<p>No, but I do know that (x-anything)^2 + (y+2)^2 = 4
wouldn’t go into Quadrant I at all, and therefore (1, 2) or (2, 1) or whatever definitely would be outside of it.</p>
<p>Yeah. Well whatever the answer was it was letter D. Do you remember the question with the answer 6!</p>
<p>Yep. 8 colors… one has to be in front, one has to be in back. How many permutations?</p>
<p>Craziness. I went to sleep after I started this thread and now it grew to 26 pages…lol. I hope I don’t miss more than 4 (I have 2 confirmed due to careless mistakes). I didn’t omit any because I was really looking for an 800, I’m going to retake it again in the fall if I don’t make 800. I kind of panicked in the test because the pacing to this test kind of threw me off…I thought we would have more time but I nearly ran out of time. I did Calculus BC as a sophomore this year, and I am frankly quite confident of my mathematical abilities…but I just hate making careless mistakes…GRR!</p>
<p>Great. I am pretty sure that I put that. The only other answers were like 8! I sure hope I put 6!</p>
<p>Nice. If you are only a 10th grader you have plently of time to take it. What math are you taking next year? Where do you want to go to college?</p>
<p>Do you really live in Taiwan?</p>
<p>yeah he does, read the very first post of this thread, he says he from taiwan</p>
<p>This is the first time ive taken the math 2c, so i cant compare how hard or easy it was to other tests.</p>
<p>What do you guys think the curve will be?
I am thinking about 43</p>
<p>Yes I am from Taiwan. I am taking Multivariable Calculus from EPGY over the summer, and I might do that next year as well through distance-learning (I already exhausted my school’s math courses). As for colleges, hmm I’m still not sure yet…but not MIT (that’s super-super-super reach) hahaha.</p>
<p>I seriously hope the curve will be 43…I’d hate it if I got 790 -_- that kills (well I’m a math-perfectionist…so…). This is also my first time taking IIC.</p>

<p>^^^^^^^^32 so far
here’s another question that was mentioned in the thread but was never given an answer, I think.
tan(x) = something and tan(y) = something else, what is whatever?</p>
<p>Any clarifications of, challenges to, or additions to the list?</p>
<p>number 1.) ((2)^.5+2)^.5= 1.82</p>
<p>bog what do u think the curve will be lol</p>
<p>Dang…that’s 4 wrong (i think already) @@" Praying that the curve will be 43!!</p>
