<p>I got 1.95, several answers could work
Grid ins were easier than usual for sure</p>

62

<p>-4a+19??????</p>

63

<p>yeahh! i got that</p>

64

<p>number one to one of the math sections was:</p>

<p>4 * pi = 4 * pi * x^2</p>

<p>was this a typo? i did not get any answer choice that had -1 or 1, but i did have ".1" which I now suspect is -1. I really hope this is the experimental section. it had a lot of weird questions like the square is divided into 4 regions.</p>

65

<p>i think it was exp</p>

66

<p>i got 1
or maybe -1</p>

<p>the square in 4 regions was 8pi</p>

67

<p>did anyone have that question about k and a parabola?</p>

68

<p>thanks god. i had four math sections. three 25 min and one short one, so I am guessing that the 4 region square one was exp.</p>

69

<p>it wasnt
sorry to say
bc i had it and i only had 3 math sections</p>

70

<p>I had four reading sections, but still recieved that problem</p>

71

<p>yep MD, k was positive 7 or 17 or yeah, the same as the other point</p>

72

<p>i had the square one too an di only had 3, it wasnt exp</p>

73

<p>ahhhhh bugger the one with the knots was experimental? argh too bad i was hoping it would be the one with finding the x intercept of the parabola and finding the gradient of line PR or sth.
Can anyone else confirm that the gradient of PR is 5/4? Its the 2nd last question on i forget which section.</p>

<p>Oh and for the apartment houses thingie, what did you get for total number of apartments? I got 200.</p>

74

<p>the k one was that f(x) is greater than K for any value that x is greater than or equal to 0 or less than 2</p>

<p>i chose 1</p>

<p>are you talking about the parabola one where you had to find the K value of f(-3)</p>

<p>if so, the answer was 17</p>

<p>f(x)=x^2 + b</p>

<p>you find that b=8</p>

75

<p>Did anyone have something about kansis city and like detroit (precipitation). Please tell me your last questions in your math questions guys.</p>

76

<p>i didnt have the rope one
or that parabola one
or that detroit on
or the cube one</p>

77

<p>weird. i had 4 math sections, but no rope</p>

78

<p>what about a graph that was directly proportional....</p>

79

<p>y=4x i believe</p>

80

<p>def 4x. yeah</p>
