<p>Im pretty sure the matrix was just adding up all 3 individually...ex. all the top left corners, all the top right corners....</p>
<p>What was the bobsleding one?
And was the last one like 15sin6 or something?
And the matix one was the bottom one, like [a+b+1/a+b c+d+1/c+d]ect ect</p>
<p>bobsled: 24.</p>
<p>why is it 24?</p>
<h2>4x3x2x1</h2>
<p>permutations</p>
<p>If it varies directly, then wouldn't there be no y-intercept because 0 can't vary with anything?</p>
<p>was the last one 15sin65???</p>
<p>h(x) varies directly with x =====> h(x) = kx
y = h(x) =====> y = kx</p>
<p>Yea that was the answer although i think it was 62 deegrees.</p>
<p>(k+h)^2+k+h+2</p>
<p>crap...for the bobsled one i said 4x4x4x4 haha...i def. didnt get a perfect score.</p>
<p>Do you guys remember the Fahrenheit and Celsius question? It's 57F outside and outside is 20F warmer than inside, what the the temp inside in C?</p>
<p>bbyy - wasn't it like 33 or somewhere around it?</p>
<p>That's the one that confused me the most. When I convert 37F to C, the answer wasn't even on there! Or am I completely missing something here o_o</p>
<p>The question said that it was 20 degrees warmer inside than outside, not the other way around. Hence the answer was actually 25C and that was on there.</p>
<p>height of rectangular box that's 20*30 and corners cut out?
i got 5, but im not sure</p>
<p>Ohh, wow I'm so mad at myself right now.</p>
<p>(77-32)x5/9=25
something like that</p>
<p>Can someone please explain the rectangular box with corners cut problem please. I had to guess on it.</p>
<p>well what i did is i drew a box and cut out 4 squares at the corners to visualize it...which led me to see that the that the area of the bottom is
(20-2x)*(30-2x)=450. i got x to be the height</p>
