<p>I thought I would give this a try... Can someone explain the inverse proportion question?</p>
<p>Well, I got y^2 because since they're inversely proportional (y=1/X), then 1/X62 should be y^2.</p>
<p>I may be wrong =X</p>
<p>they told you x = inverse of y, so x = 1/y or x is directly proportionate to 1/y</p>
<p>then they asked 1/x^2. so you have x = 1/y
take inverse of both sides to get 1/x = y
then square both sides to get 1/x^2 = y^2</p>
<p>I put y^2 too, but it was a complete guess. I hope you guys are right!</p>
<p>how about the question with circles and the area of the shaded region (may have been experimental)</p>
<p>wasn't experimental</p>
<p>i found the area of the entire circle first which is 9pi..then subtracted the white region and added back the smallest circle and got 6pi</p>
<p>the answer to the circle shaded one of 6pi.</p>
<p>Well, for the inverse proportion one...I always remember that as x gets bigger, y gets smaller. Easiest graph for that is x = -y. So then square both sides and x squared equals y squared. Seems like I was right at least!</p>
<p>I could NOT figure out the question with the cube inscribed in the sphere. I got 2 square root of 3 in the last minute and I'm pretty confident with it. Is that what everyone else got?</p>
<p>6pi for that circle problem.</p>
<p>which section was experimental?</p>
<p>I think the one with the rope beach one was experimental, unless that one was with the trippy circle section</p>
<p>was 7pi a possible answer for the circle one? (cuz i think thats what I put)</p>
<p>2 root 3 was correct
i only had 3 math sections, wouldnt there have to be 4 for one to be experimental?
the rope one i got y + 16000/y</p>
<p>"I think the one with the rope beach one was experimental"</p>
<p>Oh man, I actually got that question right, I think. I just used plug in for that one.</p>
<p>"I think the one with the rope beach one was experimental"</p>
<p>Pretty sure it was 6Pi.</p>
<p>why was the cube one not 2
area of cube was 8 so each side of the cube was 2 so diameter of cube has to be 2</p>
<p>I got 7PI at first, and I got ****ed cause it wasnt an answer, but i did it again and it turned out to be 6PI</p>
<p>and as for that rope beach one, did anybody get 90? that one was actualy easy for me</p>
<p>was the one with the cube inscribed in a sphere root 6?</p>
<p>I think I got 4 on the sphere and cube one, I had 2 square root of 3!.</p>
<p>I got the beach one too battle =P</p>
<p>yeah but thats the diagonal of a side...not the whole cube</p>
<p>the rope beach one only involved x and y's. i think you got the problems mixed up.</p>
