<p>i thought the k one was 7</p>
<p>Does anyone remember what they got for the last one?
It was about a plane and 10 non parallell lines.
It's asked how many points touched all lines (or something).
I believe I put 100 (a guess).</p>
<p>45 points</p>
<p>what was 49 with f(t) = 1
i put t = 2 (A)</p>
<p>the k one was the cuboidal equation with a factor of (x-1)
i put k=2
any confirm?</p>
<p>Several of my answers (tell me if I'm wrong):
10 different subcomittees (you do 3nCr2 in your calculator, i think?)
4 spheres can fit in the rectangular box
E? for the only solution thing
1080 for the SUM of the angles in an octagon
1.53 was the GREATEST zero
2 and 4 for cos of the angle
sum of 43 number must be 7
All real numbers for 16+x^2</p>
<p>AlexMartin: 2 pi for semicircle area? I thought it was 19?/something...or some kind of fraction? I wasn't too sure though
By the way, what kind of pattern did you use for the points and lines thing (the last question)? I didn't understand how to do that one.</p>
<p>primeminister, you're right.
there goes my 800.
im cancelling.
bye.</p>
<p>are you sure the answers 2 for 49?</p>
<p>yea i had 2 for no.49 as well</p>

<p>Cud anyone plz confirm if this is correct?????</p>
<p>just to be clear, the (6, m) and (m-1, 3) problem was -.46</p>
<p>its just asking for the slope...which would be:</p>
<p>(3-m)/(m-1-6)=m....if u have a TI 89 like me, u could just type that equation and get the answer...m=-.46 and 6.46</p>
<p>guys...this was the same test as IC from october 9th 2004. Check old threads from CC!!!</p>
<p>krishna...ur right. it is -.46</p>
<p>whoa...they actually reuse tests!!!!!!!!!!!!thats **<strong><em>...i wouldve just studied old tests then!!!! *</em></strong>! the practice tests i took did not contain that one. *!</p>
<p>hey AlexMartin, i think number 49 was 7.
it said f(2x+3)=4x-7, by inspection one may figure out the original function to be f(x)=2x-13;
set this equal to 1 because they ask for value of x is f(t)=1
1=2x-13
2x=14
x=7</p>
<p>by the way i think the only solution problem was B? A and E were the exact same line as the problem (infinite solutions), C and D were parallel to the line in the problem (no solution). B had a different slope than the problem so it crossed at one point. </p>
<p>come to think of it, i can't remember if the line with a different slope was B, but i'm almost positive it wasn't E</p>
<p>Yeah..i thought problem 49 was 7</p>
<p>exactly what was the question asking?</p>
<p>Also..whatd you guys get for the area of the semi-circle one?</p>
<p>i think i put 17/4 pi</p>
<p>You guys are strange. Why didn't you all just take the IIC?</p>
<p>because IIC is cake.</p>
<p>Also..whatd you guys get for the area of the semi-circle one?</p>
<p>i think i put 17/4 pi</p>
<p>i had 17/4 pi also</p>
<p>Crap....no no I had 2pie (:)) I want some pumpkin pie now....</p>
<p>For the cosine problem, that everyone said was 2 and 4, do you remember what <em>letter</em> answer that was, A-E? I think I guessed last minute, but I can't remember waht the letter corresponded to.</p>
