<p>No. I don't really remember the question.</p>
<p>|x^3-5| < 8</p>
<p>I got -1.4<x<2.35 (or whatever the decimal number was).</p>
<p>yeah, thats right nervous, i put that too, just split the absolute value</p>
<p>Did you guys get 21.6 for the arithmetic mean one?</p>
<p>I concur with the above 2 posts- I graphed the function</p>
<p>"Did you guys get 21.6 for the arithmetic mean one?"</p>
<p>Yup. :)</p>
<p>sigh... i skipped 2 and got like 3-4 wrong... i hope the curve is a little bit lenient...</p>
<p>:(</p>
<p>How about:
An airplane is at an altitude of 8 km flying towards cities A and B. Angles 37,25... Distace between A and B?
I got 2.3 or 2.5... forgot what the exact decimal was, but it was the only choice close to my calculations.<br>
I used tan to get the base to the left of the first city, then did law of sines to get the answer.</p>
<p>wait, so the plane intersection one was point and line, but not ray...</p>
<h2>I sincerely hope so, i can't afford to lose any more points :(</h2>
<p>nervous, it was like two parallel lines intersected by a transversal, so it was alt. interior angles are congruent theorem thingy</p>
<p>so, taking the tan of both 37 and 25 and subtracting the distances (I think 15.7 -9.9) was the answer</p>
<p>I put ray, line, and point. I wasn't sure though =</p>
<p>And for the one that gives you a table of x and f(x) and says: If f(f(x)) = 6, what is x?
I got x = 2. f(2) was 3 and f(3) was 6.</p>
<p>yeah nervous that was the answer</p>
<p>and im pretty sure it was just line and point, cause a ray terminates at one endpoint, while the planes continue forever...</p>
<p>plus i got this awesomely cool program in my calc that gives me the sides and angles of a triangle that i input answers for... screw memorzing the law of sines and cosines!!!</p>
<p>:D</p>
<p>best case scenario for me is a 42, which would be a 790 per last year's curve...but i'll probably miss a lot more than that, so meh</p>
<p>But if you memorize the laws, it's faster than going to a program and doing all that stuff :P</p>
<p>a 42 was really a 790? wow!</p>
<p>yeah, i know it would be faster, but for questions where it was the triangle split into 2 right triangles with two angles and a side(ASA), i just plugged in the stuff and got 11.0 for the answer...which i hope is right!?</p>
<p>craaaaap. i definitely got the white car/2 door problem wrong (i misread it) and the three plane intersection one wrong. i dunno how many else i missed.</p>
<p>i skipped three, i think...</p>
<p>I can't remember that question for some reason (two triangles)...</p>
<p>How about the question that asked: How many subsets can you get from 3 or 4 out of 5? That was weird. As far as I can remember from what I read in Barrons, 2^x is the subsets I think. So I did 2^3 + 2^4 = 24. So I just went with 25.</p>
<p>How about the question:
Which interval contains solutions to:
(x+3)(x+2)(x-2)(x-4) < 0</p>
<p>I automatically ruled out the positive intervals (since <0) but then I was stuck on two of them. I chose -3>x>-2.</p>
<p>hmmm i dont think you can automatically rule out the positive intervals...just my opinion tho</p>
<p>But the solutions are -3,-2,2,4. If x < 0, then it only leaves -3 and -2, neither of which are in positive intervals.</p>
