<p>some of these were impossible ffs I skipped 7 8)</p>

<p>Does anyone remember the sin u + cos alpha question and which one it couldn’t be?</p>

<p>^150</p>

<p>10char</p>

<p>What was the one with a cosine function and something else modeling populations asking how many times they intersect</p>

<p>I said 150 (I think) for that, WannabeActuary.</p>

<p>@njman94 I WANT TO KNOW THAT TOO</p>

<p>^ njman94</p>

<p>I think they intersected 6 times.</p>

<p>they intersected 6 times</p>

<p>NINJA’D :o</p>

<p>I also put 6 intersections</p>

<p>was the conic centered at (-2,5)?</p>

<p>how generous do you guys think the curve will be?</p>

<p>Violinplayer: </p>

<p>I think so…but since all of the answers had twos and fives I might be getting it mixed up.</p>

<p>I’m pretty sure the answer was 150. There were 14 rectangles of 2 x 5 cm, and then one that was partially a rectangle, making the area roughly 150.</p>

<p>it was like ((x+2)^2) / 9 - (y -5)^2 / 4 = 1
i got -2,5</p>

<p>I agree with the center of (-2,5)</p>

<p>I thought that was pretty hard D:
Also got -2,5</p>

<p>The last question -1, right?</p>

<p>What was the last question? I can’t remember it haha</p>

<p>^ Yeah. </p>

<p>10char</p>

<p>Given the period of 3, a-1, a, a+1</p>

<p>Yes. The last question was -1</p>

<p>What was the volume answer?</p>
