<p>i thought 9 blank would be more like a 750 or +</p>
<p>9 blank is DEFINITELY not a 670. You must have gotten around 5 additional questions wrong.</p>

Barum, </p>
<p>cos^2x= -sq (1-sin^2x)
what is x located?

</p>
<p>It's the 4th quadrant. Damn, I just realized my mistake. I accidently plugged in 90 and regarded it as the 2nd quadrant.</p>
<p>Oh well, 4 omit and 4 wrong. 41 raw score, I think that's about a 790 or 770. I'm more than happy.</p>
<p>About the problem right above ^^</p>
<p>Isn't it for every angle??</p>
<p>From what i remember the cos was not squared.
So I squared both sides, and i got cos^2 x + sin^2 x = 1.</p>
<p>(I'm not entirely sure though)</p>
<p>It's not the 4th quad...It's 2nd and 3rd.</p>
<p>Nbach, </p>
<p>I dont think it could have been the 4th quad.</p>
<p>I remember the answer choices pretty clearly (though not in order)</p>
<p>a) 2, 3rd quadrant
b) 1, 2nd quadrant
c) 0 degrees
d) All values x
e) No values x</p>
<p>Does anyone have an answer to the last problem? I put 0.52</p>
<p>0.6<em>(1 - 0.4) + 0.4</em>(1 - 0.6)=0.52 is this right?</p>
<p>"From what i remember the cos was not squared.
So I squared both sides, and i got cos^2 x + sin^2 x = 1."</p>
<p>sorry you're right. the cos wasn't squared.</p>
<p>Goldfish, for the probability problem, i did 1-(1-0.6)(1-0.4), because it said they are independent events, so complement of non of them happening is when at least one of them happens, thus the equation above.</p>
<p>^+1</p>
<p>The answer was 1-.24 = .76</p>
<p>the last problem was E...
i think i got 48 right 2 wrong...
omg so worried.. should i cancel? LOL</p>
<p>what do you think the curve will be like??? I'm really scared that I did bad... thinking of canceling it - ahhhh</p>
<p>I don't get it...why cancel? Who cares, really? They aren't going to look at a single "bad" score and throw your application into the defer/rejection pile...so what, you may have not gotten the exact score you wanted, but you just want through waking up early on a Saturday morning, probably studying leading up to it and now you aren't even going to see how you do?</p>
<p>does anyone know the answer to the question that went like f(x)= 4x-1 and solve for f(2x) for all values x..?</p>
<p>Yeah, I probably did get others wrong. It was the first time taking a collegeboard test, so I probably made some stupid mistakes.</p>
<p>bumppp, my question?</p>
<p>Goldfish, it said F(g(x)) = 2x-1, and g(x)=4x, so f(x) must equal x/2 - 1 (just plug in 4x for x).</p>
<p>whats 15 omit</p>
<p>Darn that's 5 I missed. 0 omitted. So what's my score now?</p>
<p>800 according to Princeton Review.</p>
