<p>50 had to do with logs somethin like log(1+sinx) + … don’t remember the answer but i plugged and chugged</p>
<p>that was #5 lol</p>
<p>50 was like this (Log sin -1) + (log sin +1) = 2 log cos x</p>
<p>i was just going to say that lol</p>
<p>oh sorry i thought they were in order lol i guess that would be a little difficult to remember every exact question number ha</p>
<p>im not positive, but i remember something easy like if f(2) = 6 then solve for k:
f(x) = 2x - k (i just vaguely remember something similar).</p>
<p>does anyone remember if the answer to (#20 on the CC list) y-3=cos(2(x+5)) was letter C? thanks</p>
<p>oh i remember that one. it was like f(2)+4f(1) = ? if f(x) = something</p>
<p>Thanks upton, that is the exact problem!</p>
<p>If f(2) = 6 then solve for c: f(x) = 2x - c; c = -2</p>
<p>We are down to ONE left folks!</p>
<p>the question
(X-3)^2(X^2+1)=0, (X-4)^2(X^2+1)=?</p>
<p>it was A. -10 right?</p>
<p>does anyone remember how to do the question that asks for area of a feeding plank? and #50</p>
<p>bojangles</p>
<p>i did the same thing, but then i gave up and ran outta time
162 right?</p>
<p>I remember something like </p>
<p>If f(2) = 4f(1), what is f(x)?</p>
<p>That’s this
30. f(x) = x + k/x. If f(2)=4f(1), what is k? k = -4/7</p>
<p>Ya I just saw that. The last problem really doesn’t matter unless you’re borderline 800.</p>
<p>does anyone remember what letter 28 was???</p>
<p>the one where the answer was .952 (sin(sinx) = .3 or something, was .954 also an answer choice?
Also does anyone remember what letter choice the 64a one was</p>
<p>.952 .954 .955 were all answer choices.</p>
<p>.954 would be what you get if you only take the sin inverse once.</p>

<p>Xeaqs8, you sir, are a god. Thanks for the effort!</p>
<p>So far I’m 1 wrong, 6 omit. Looks like I’m on the tip of the 800 >.<. Let’s hope that last problem was an easy one that I got right…</p>
<h1>50 might be something like that:</h1>
<p>cos(1.14) = cos (x) for all x EXCEPT 1.14 + pi.</p>
<p>Was there #51?
True for some x
I. (sinx)^2 + (cosx)^2 = 2
II. 2(sinx)^2 + (cosx)^2 = 2
III. (sinx)^2 + 2(cosx)^2 = 1</p>
