<p>Sorry teriyarki, I completely forgot.</p>

<p>Rainbow, you can get like -16 on your raw score and still be 700 or above ;)</p>

<p>^wow, really? Can you please link that to me? hahaha</p>

<p>Your raw score can be a 33 and still score 700

<p>Hey guys, do you remember the question asking for “What is the value for n” and it gives you f(x) = nx and something about f(f(x))? I put 0 and 1 only, since:</p>

<ol>
<li>For n=1, f(1) = x and f(f(x))= f(x) = x so both equal x</li>
<li>For n=0, f(0) = 0x = 0. f(f(x)) = f(0) = 0.</li>
</ol>

<p>Any number would make f(x) not equal f(f(x)). Do you guys remember the correct answer for this problem?</p>

<p>Wow. That is a very generous curve. The curve isn’t so good in my CB book, though ): I’m really hoping for a 700 or +.</p>

<p>

</p>

<p>I put -1, 1</p>

<p>@mcs735: yeahh me too</p>

<p>Can someone explain why it is f(5)+g(20) instead of 5f(x)+20g(x)?</p>

<ol>
<li>8.246 for the altitude of the triangle (((side/2)^2 + (height)^2)^(1/2))</li>
</ol>

<p>Ehh I have no idea which one this is??</p>

<p>@Jungian, it’s like u substitue x=5, and x=20 into the fuction …</p>

<p>did anyone get 34 or 35 (can’t remember which) for the question with the diagonal of the parallelogram (side lengths 22 and 24)</p>

<p>34 i think…C maybe?</p>

<p>yea i got that too, but for some reason, i remember thinking i was wrong when i put that down</p>

<p>can someone explain that one to me?</p>

<p>I didn’t answer it, but I probably could’ve arrived at 34 through guesswork. You could split the parallelogram into two triangles, and the angle opposite the line you were solving for was 105 degrees. Meaning it had to be quite a bit longer than the other sides, which were 22 and 24. The first three answers were too small, leaving only 34 and 44 (I think). And then the whole a+b>c rule for triangle lengths would have indicated 44 was too large a value, so 34 was the sensible choice.</p>

<p>Damn, I wish I had thought of that during the test.</p>

<p>Arggg. You see I was trying to do something funky with the law of sines >.<</p>

<p>That makes a lot more sense. Thanks.</p>

<p>So was I. Which is why I didn’t get around to answering it.</p>

<p>Heroes of the day: my TI-89 and the Law of Sines.</p>

<p>I used the cos rule to get 34 for that question.</p>

<p>^
Me too!</p>

<p>First, I am kind of new here, so I am sorry for intruding into the thread. ^^</p>

<p>I have just one question regarding the problem with the decay by 25% of the stupid syrup. Did someone get something like 18.3???</p>

<p>PS: By the way, isn’t it sort of illegal to discuss stuff from the test? :smiley: I don’t want to get my scores cancelled…</p>
