<p>Box and Whiskers I essentially rounded up and used the quartiles to get ~50%.</p>

82

<p>x^2 < 2^x @ x= 5
x^2 > 2^x @ x= 3
x^2 = 2^x @ x=4</p>

83

<p>dam…is the curve going to be 44 or 43. Fingers crossed for 43.</p>

84

<p>I got fifteen as well (:</p>

<p>How does a 4 wrong and 2 omit sound? Would it be a solid 790-800?</p>

85

<p>what was the Sin of that obtuse angle opposite to the side radical37</p>

86

<p>This image essentially explains it all for the x^2 and 2^x problem:

</a></p>

87

<p>whats -2 omit 5?</p>

88

<p>Worst case: RAW score of a 40…what’s that equal to? :P</p>

89

<p>Philsophydude: if x=4, then x^2=2^x (both are 16)</p>

90

<p>@mathisfun</p>

<p>hopefully 760 or 770 (hopefully the latter)</p>

91

<p>What did you guys get for the which one of these functions is not the same as the others ones.
It was like -b=(-a)^2 and some other options. I put E b=(-a)^2</p>

92

<p>anyone remember the y-k= a(h-k) graph?</p>

93

<p>@Yulesh yup!</p>

94

<p>I put that as well Yulesh (:</p>

95

<p>@yulesh, yeah E</p>

96

<p>what about the one that had the sin A=2, find cos A. I just plugged into the trig identity using radian mode, idt that’s right though</p>

97

<p>@jackson radical 3 is what i got</p>

98

<p>One more question :P. What the answer to the one with the two graphs of domain 2<x<2 and it asked what was the transformation to the first graph. I put -f(-x)</p>

99

<p>@Yulesh. As did I. It was about the origin so -f(-x)</p>

100

<p>What did you guys get for the closest to y=15 for the elipse? 12? </p>

<p>Oh and the last one.</p>
