    How many marks was the part where you had to show the minimus cost. I think that's the only mark I'll lose out

    Same. Just that I didn't take 3 put of the bracket. Feeling regret a little bit now
    I put (2x+1)(3x-24)(x+6) or something to that effect

    God I hate factorising polynomials like that.

    Hi there, I got to the point of forming the quadratic using the identities but then I didnt solve it correctly, do you think I would get 2/3 or only 1/3 for forming the quadratic (I completed the square instead of formula lol)
    you'd get 2/3 if you got to the quadratic stage

    checked with my friends and decide to put these down before I forget... :llama:

    - a= -48, b = -96 (might have mixed them up, can't remember)
    - Factorise f(x) = 3(2x+1)(x-4)(x+4)
    - common ratio: 8/9, first term = 18, n = 28
    - Area of graph = 226 sq. units
    - Perimeter = 40.9 cm; Area = 96.7 cm^2
    - the minimum cost for the cylinder is 483 pounds
    - Angles from tan: pi/9, 4pi/9, 7pi/9; angles from cos: 0. 139, 221 (3 s.f.)

    Hope they are correct! Waiting for Arsey's unofficial mark scheme though hahahaaa

    No
    If you arent sure you can substitute 27 or 28 in and only 28 gave a value greater than 290

    How do you do that sequences question??
    Eek sorry didn't answer yor question properly.
    Calculate S2 and S infinity and divide them and you get r^2=64/81.
    The second one is quite complicated so I will probably write it down later for you.
    Do you remember the exact question?

    I wrote (6X+3) so pretty much the same
    Some one just told that it would cost only 1 mark so don't worry.
    But it is correct so we shouldn't lose any marks.
