<p>Personally thought it was pretty easy!</p>
<p>I thought most of it was pretty easy. Unfortunately, I got caught up on the table with the wins for a few minutes because of some super stupid mistakes, and I didn’t really get to the last two. I made an very fast guess on the last one, and when I graphed it after the exam, I think I was right [I put that the graph was abs(x^2 - a)].</p>
<p>I don’t think a got the second to last question right (the one with the overlapping circles). I put E, which said there wasn’t enough information, though thinking back I was pretty sure this was wrong and should have probably guessed between the other 4 choices. What did you guys get for this one?</p>
<p>30 I’m pretty sure!</p>
<p>Number 59 (the two congruent circles one) was 30 degrees (B I think?)</p>
<p>The line connecting the centers was equal to the radius, as were the lines that formed the lines that made the diamond/rhombus/parallelogram thing in the middle. Since the short side of the triangle is half of that radius, and the long side (hypotenuse) was the radius, a 30-60-90 special triangle is formed (because the short side was exactly half of the hypotenuse). The angle that was to be found was the 30 degree angle. </p>
<p>Unless I’m wrong, of course.</p>
<p>if points M, N, and B are in a circle, what is the radius?</p>
<p>radius is 5</p>
