<p>What was the pyramid question? Were there two versions?</p>
<p>It was just the one with the dot structures...not really a pyramid, more of a triangle on top of a square. 2-dimensional.</p>
<p>what about the probability of getting a 1 and a 2 on the cubes with something like 1, 1,1,2,2,2 and 1,2,2,2,2,2?</p>
<p>It was 1,1,2,2,2,2 and 1,2,2,2,2,2</p>
<p>And you just do (1/3)(5/6) + (2/3)(1/6) = 14/36</p>
<p>There's only two ways to get a one and a two, so you find the probability of getting it each way and add them.</p>
<p>it was 1,1,2,2,2,2, and 1,2,2,2,2,2</p>
<p>I got 14/36</p>
<p>Just curious, but what math classes are you guys in?</p>
<p>1) what about the triangle on the xy plane with hypotenuse (length=8) and angle aob of 23 degrees? the question asked us to find the x coordinate for point A. I think I put -3.13 something like that.</p>
<p>2) the population in 2.3 hours? there were 5 members at t=0 and doubles every 23 minutes.</p>
<p>3) the sequence question that asked for a equation equivalent to it?</p>
<p>1) I put -3.13
2) I put 320
3)Which one?</p>
<p>Did you edit or something? I put 2^k-1</p>
<p>im in ap calc bc but the first time i took math iic in june i got 680. this time had better be better.</p>
<p>I'm in AP Calc AB</p>
<p>Goldfish, I'm in Calc II/III...we kind of finish up CalcI/II early in the year and then move on to multivariable calc and differential equations. We pretty much have just finished covering everything that the Calc BC exam covers, so our next unit will deal with differential equations/MV calc, which is really just for our own good since pretty much everyone has to take Calc III in college anyway.</p>
<p>What about you?</p>
<p>Also - I got all those same answers...that 2^(k-1) one took me like 5 minutes for some reason though, lol.</p>
<p>For the angle (3.13), all you had to do was -8sin(23) since it was a right triangle.</p>
<p>If you multiply 2.3 hours by 60, and divide by 23, you see it doubles 6 times.</p>
<p>5 > 10 > 20 > 40 > 80 > 160 > 320</p>
<p>I finished AP calc junior yr, my school created a special class called "Advanced Calculus" for all the kids who took ap calc junior yr, and got a 4+.</p>
<p>It teaches you post-BC stuff, vector clac, partial derivs, multiple integrals, quadric surfaces, differential eq's (2nd order), and eigenvectors and stuff like that.</p>
<p>Yeah, it doubles 6 times..So it was um...60 right?</p>
<p>I think I got about 5-10 wrong. What will I probably get?</p>
<p>You will get a score in the range of 750-800.</p>
<p>Not bad...</p>
<p>how do you do the question about Sk=k or somethin like that
and how do you change (.5, -sqr3/2) to its polar form</p>
<p>I'm taking AP calc AB too. (Too bad our school doesn't offer any more advanced course)</p>
<p>I actually was nervous about this test, because I skipped precalc, and just studied it over the summer by myself. (Long story behind how that happened)</p>
<p>So far, I don't think I got any question wrong so yay~</p>
