<p>I don’t remember a rectangle inscribed in a circle or a gold cube on my test.</p>

62

<p>A CCer mentioned earlier that the f(x+3) = f(x)*f(3) problem was e^x?</p>

<p>Did anyone else get log(x)? Or something along those lines…QQ</p>

63

<p>i think the cube one was on math 1…and i got 675 too</p>

64

<p>feedback411: the standard dev one was the answer with all the 10s, i believe it was 8 10 10 10 10 12.
edges is 15 right? 5 for each base and 5 to connect them</p>

65

<p>How many edges on the pentagon prism question? I got 10…</p>

66

<p>i got 15 for edges</p>

67

<p>^Oh yeah…you’re right! It is 15…</p>

68

<p>I put 15, not sure though</p>

<p>5 on pentagon+5 on rectangles+ 5 on other pentagon</p>

69

<p>15? o.o blah.</p>

<p>and the question about x^2 and 2^x, was it all three?</p>

70

<p>yea joe :)</p>

71

<p>Edges - I said 15 since there are in addition the 5 edges where the faces meet. </p>

72

<p>iiClickSend: yes, all 3. they can be equal, one can be less than each other (when x is 3), and anything higher than 4 the other one is greater.</p>

73

<p>I don’t think X^2 and 2^x were equal past 2.</p>

74

<p>Yes for the x^2 = 2^x I got all 3 as well.</p>

<p>@Philsophydude Graph it. They have an intersection point around 4.</p>

75

<p>What was the box and whisker plot one?</p>

<p>And the guy who bought n CD’s for a discount of d at x price for previously viewed movies…or something like that? Can anyone explain what on earth was going on in that problem T.T</p>

76

<p>i couldnt prove that x^2 and 2^x were equal past 2, however i WAS able to prove both of the others, and ALL 3 was the only answer choice that had 2 and 3 together as anwers so i believe it is ALL</p>

77

<p>did anyone get 4% for a cone question? D: i forget how it was worded exactly</p>

<p>box & whisker = 50%
CDS - x=n/0.6d (something like that)</p>

78

<p>Laurier: Box and whisker was 50%. I know the second problem you’re talking about but I can’t recall it in its entirety at teh moment.</p>

79

<p>For x^2 and 2^x, I got I only one of the choices…since after the intersection of (2,4) at x=2, x^2 never exceeds 2^x and the two equations do not intersect beyond x=2.</p>

80

<p>I don’t understand why we have to wait 12 days for our scores</p>

<p>I mean it’s a scantron test right?</p>
