    4. Equation of circle : (x+1)^2 + (y-3)^2 =50
    Centre = (-1,3)
    Radius = rt50
    K = (-2,8)
    Shortest distance (C to QR) = 7
    In this question didnt it ask for two possible values of the y coordinate for k? I had to use the quadratic equation and got something like 3 plus or minus root33

    Cylinder question I messed up the first 5 marks. But the second part of it was okay.

    Did anyone get k = 8 or -8 for the last question on solving inequalities?
    You needed to use critical values

    was 62 for an a last year and with the majority of people not getting the cylinder volume question right wouldn't imagine it would be any higher than 60 for an A

    anyone know how we were supposed to sketch the graph?
    I sketched a cubic with points at x-intercepts at -3, 0, 3

    for question x+2 (x^2+bx+c)

    i for c as 10 but b as -1 so -x
    did u have to expand brackets?

    I also got -4/9 as the factorised quadratic inequality was (9k+4)(k-4)<0

    There was a double '0' root. so it started under the x axis and to the left of the y axis, the went up to the origin, touched it, went back down, then went back up to '3' on the a axis and passed above to x axis to the right of the y axis.

    The formula for the area of a cylinder was in the formulae booklet...guessing no one thought of looking in there, during a core 1 paper 😂

    Can you write the general topic of each question?) might jog people's memory

    i don't understand what you mean! i did it so that the curve touched the 3 on x axis and went up and down towards 0
