    Did anyone get k (in the translation question) as 5.5?

    Arc in triangle question? I got 10.32, everyone I talked to used the same method as me but got different answers 0.o
    I thought I got that one, but apparently its like 13.7 and I don't remember writing that.. Almost forgot to add the arc length on but spotted it with 10 mins to go :P

    for K i got 13.5....
    and the transformation was a stretch in y SF 3?
    I changed stretch s.f. 1/3 in x-direction after writing what you did. I don't think s.f. 3 in y-direction is right because when you expanded both it was y=X+3 changes to y=3X+3 or something

    I got:

    65.6 for the trapezium rule question
    6 for U12 near the end
    and for the sigma question at the end I got 90???

    anyone get any of these

    d) k = 5.5
    4. b) d = -2, a = 28
    c) Sum to 21 - sum to 3. Can't remember exact.
    5. b) area = 19.9
    c) perimeter = 13.8 (something like that)
    6. a) 65.6
    b) i) translation (0,5)
    ii) stretch in X-direction 1/3 sf
    7. b) -1648
    8. b) can't remember! Tan(X) = 1 and tan(X) =-5/4
    c) lowest = 2, when theta = pi
    9. a) c^(m/2 +6n)
    b) X = 5/2

    U12=6 seems familiar. I had a bit of a crisis with the trapezium rule, but I think I should've got it right, although idk if I put 65.6

    Arc in triangle question? I got 10.32, everyone I talked to used the same method as me but got different answers 0.o
    I got like ~3.41 for the arc length for the triangle and something like ~5.86 for r. I think you had to say that 1/2 r^2 x = 19.9(area of triangle)-1/2 r^2 x, therefore r^2 x = 19.9. You already know x, so substitute it in and get r^2 to be ~34 and r = 5.86 ish. Final perimeter should be about 13.7 or 13.8 depending on how you've rounded in the question.

    Of course, I could be completely wrong
