    Anybody wanna scan in this paper and number answers?
    I can help you out for most of the answers but I havent got the paper anymore....


    1) y = 1.5x + 0.5

    2a) 17 - 12 root 2
    b) 0.5 + 0.25 root 2

    3a) x^2 graph and line with negative gradient
    b) Meets axis at (-2,0), (2,0) & (0,-4)
    c) Points of Intersection (1,-3) & (-4,12)

    4a) X< 65
    b) x^2 + 20x - 4800 > 0
    c) 60 < X < 65

    5a) Tan x = 8/3
    b) x = 69.4 & 249.4
    c) x = 70.5 & 289.5

    6)prove by taking second derivative is > 0

    7a) Prove AP by writing it out, multiplying by r, subtracting, factorising and rearranging
    b) 87.8
    c) 100
    d) 10/11

    8) Q(3,12) & P(1,12)
    Line PQ is parallel to x axis => gradient of PQ = 0
    Area = 4/3

    I think these are correct anyway, I have about 10 seconds to redo the paper before my friend needed it returning so I scribbled my lil' ass off.
