1

<p>Same as the title.</p>

<p>Time to discuss.</p>

2

<p>Matrix one?
The about about the milk, and making it cheaper, I think I got that
y(1/x) - what can't be true?
Very last problem.</p>

3

<p>for the y(1/x) problem, wasnt the one that couldnt be true be the last answer choicde (X^5 + Y^5= 1)?</p>

4

<p>Yep! I put the same as dumbstruck.</p>

5

<p>yeah it was E.</p>

6

<p>last one answer was pie.</p>

7

<p>Def. didn't get that =(</p>

8

<p>does anyone remember any other questions? hmm...what about where it asked to find the central angle??? I got 20 for that....it had to do with a pie chart...</p>

9

<p>these are some of the answers i remember, dunno if they're right</p>

<p>matrix k=-3
last answer pie
degrees 75
lowest sine E, on the furthest right
weird looking shape, ask for area 23
Gallon fuel question .05 gallon used per mile
something about percent 53(1/3)%
44....something soda sold, i think thats the first question
weird X-B>4 answer.....i put A
large gallon vs small gallon......5/6</p>

<p>So whats the name of that weird Cos looking graph? and whats the shape when y=X??</p>

10

<p>how were you supposed to do that one that asked for the smallest sine and had like 4 or 5 angles coming off the same line going up to the same point forming a bunch of triangles. i guessed and said it was the triangle with the biggest angle in its bottom right corner... </p>

<p>is that right?</p>

11

<p>if you plugged in random numbers you would find that it decreases. answer was E the farthest right!</p>

12

<p>for the matrix one, which letter choice was k=-3?</p>

13

<p>i think A or B</p>

14

<p>for the matriz one i jus put in -4 ??
what was it ....so random a guess
it was so easy though</p>

15

<p>I got all the same answers as betterday55 IIRC</p>

16

<p>"weird looking shape, ask for area 23"...why was it 23...wasnt it 24</p>

17

<p>24 wasnt an answer choice</p>

<p>" large gallon vs small gallon......5/6"</p>

<p>which one was that?</p>

18

<p>did any one else get 51 2/3 instead of 53 1/3 degrees?</p>

<p>I marked 53 1/3 because it was closest but my math didn't come out exactly as the answer</p>

19

<p>I put 51 2/3 too.</p>

20

<p>^ Which question was that?</p>
