<p>I believe I said 16 pi for that one, I’m not sure if it’s right though. What was the last one with the ratio of the area? I said 1/26 but I kept getting 1/11 and 1/23 which weren’t choices.</p>

22

<p>What about the one for x-y</p>

23

<p>Yeah what was the (x-y) question?</p>

24

<p>for the x-y question i got 2X and for the shaded cirlce question i just guessed 16pi. What about the question where it was f-1(f(x))?</p>

25

<p>I think I got that as well. I’m not too sure about the f-1(f(x)). I got 9 for the log5(125) x log2(8)/log… Anyone else?</p>

26

<p>ya it was 9</p>

27

<p>I hope the curve is generous though, because I made a few simple mistakes.</p>

28

<p>what did you guys get for the question that said something like the 100 cubic centimers. anwser choices were 28, 129??</p>

29

<p>I think it was 28…but I don’t really remember. Anyone get 184.7 for the triangle question(law of sines)?</p>

30

<p>f-1(f(x)) is x. The 100 cubic centimeters one was 129. ((cubed root 100)^2)*6</p>

31

<p>so the anwser to the f(x) question wasnt f(x-2)?</p>

32

<p>that was a different one, but the answer was f(x+2) because it said it was shifted two to the left</p>

33

<p>I have a few questions:

  1. the zero of the equation that started with 2x^4<br>
  2. Number 49 - the ratio of the areas of the right circular cylinders
  3. number 50 - forgot what it was but what letter choice was right?</p>
34

<p>does anyone remember the question like: if 2x+2y=0 what is x-y? also how about the one where they give coordinates of a point on like a triangle thing and u had to solve for the coordinates of one of the points?</p>

35

<p>I got that x-y was 0</p>

36

<p>i got that too… but mainly because i just took an educated guess haha i’m not sure why it’d be only 0… cuz i thought of ways of possibly getting the other options as well</p>

37

<p>I thought the test was hard :/</p>
