<p>Lets Discuss!!!!!!!!!!!!!</p>

<p>what was the answer to that damn question with chored parallel to diameter...</p>

<p>That question was really, really cool. I got it, but im not discussing till tomorrow.</p>

<p>i left the chord anser blank...</p>

<h1>50 was 10.. choice D</h1>

<p>Ah, i left # 35, 41, and 50. #41 was about a ball with radius 1, i should have got that right, i was close.. skipped 3 total. But besides those 3 questions, I think I did well.</p>

<p>the ball w/ radius 1 anser was 16</p>

<p>how you get 16?</p>

<p>chord parallel to diameter you made a triangle with 2 radius's and then the chord .</p>

<p>for the radius ball one, the balls take up 2x2x2 so i dont see how its 16. what were the dimensios of the box?</p>

<p>ok the chord and diamterer one was root3 i figured that out and the ball question was like 4 or something like that i forgot...</p>

<p>yah igot 4 for the ball question, phew i thought i got it wrong ;)</p>

<p>Anybody remembers matrices from #49?</p>

<h1>bump</h1>

<p>root(3) for the chord/diameter
4.42 for the weird triangle problem
4 for the ball with a radius of 1 problem.</p>

<p>matrix problem..</p>

<p>anwser choice A</p>

<p>Haha, was it really A?</p>

<p>what was A?</p>

<p>It was a=0, b=0, c=0.</p>

<p><em>bump</em>, I want to know about the matrix problem as well.</p>

<p>it was a=-b or b=-c or something. something equals negative something else. i took the time in the test to see if it worked with -2 and 2 and it did, as well as with 0 and 0. </p>

<p>pretty sure about this</p>

<p>Dammit. Now I'm down to a 790. </p>

<p>Does anyone remember the triangle-within-a-triangle problem? I got 4.42, but my friend got 8.42 (or something like that). Anyone?</p>
