<p>For the midpoint one. I believe it was D. As least thats what i put.</p>
<p>Can you teach me why its 3.2?</p>
<p>I just hope I make a 700. That's all I want. After taking chemistry and biology, I was completely fried. I mean I don't think that I dipped below 750, but I wouldn't be surprised if the actual score was lower than that.</p>
<p>I skipped none and I know for sure I got 3 wrong, there are 7 others that I am iffy about so the possbilties go from a low of rs 36(710-730) up to 46(800)</p>
<p>What why was the answer in minutes and not hours!!!! about the circulation one!</p>
<p>Could sb please post the cliff problem . I think the right answer is 4.2 or 42 and not 72 .</p>
<p>There was a cube one where I put 2<em>3</em>(5/root2). Don't have a calculator so I can't calculate it off hand.</p>
<p>The midpoint question was (-4, -6).</p>
<p>grr i omitted 7 :(</p>
<p>Hey - was the last question about matrices - because i feel like i didn't turn the page.</p>
<p>The last question concerned the properties of matrix dimensions.</p>
<p>How could two spheres intersect to make a circle, and why would the spheres be hollow? A sphere is a 3-dimensional object, not the frame of one.</p>
<p>What was the answer to the question about increasing graphs?</p>
<p>it said spherical surface, that's why we assume they were hollow</p>
<p>yeah about the sphere question how can it possibly be a point, dot 2 spheres intersect in 2 points always and also why can it not be a circle and a sphere??</p>
<p>when they are tangent to eachother, they intersect at one point</p>
<p>when they cross over, they make a circle</p>
<p>btw, was there a math comp the day of the Math IIC test? I heard that as a rumor, and this might give me hope in getting a better curve</p>
<p>anyone know what 4 omitted and 8 wrong works out to be?</p>
<p>About the problem concerning the number of real roots, it didn't say that a is not 0. If a were 0, then you could have 0 real roots. So is it 0 the answer? I hope not ;-) However, it didn't sound ok 'at least 0 roots' as the statement would have been, not that it does matter. So what do you guys think?</p>
<p>Nah, even collegeboard wouldnt pull that crap</p>
<p>So, what's 1 wrong and 0 omitted?</p>
<p>[/sarcasm]</p>
<p>an 810. good job :P</p>
<p>When spheres cross over, they form a sphere, technically an ellipse as the interesection.</p>
