Can anyone explain how its 120 for the minimum value of P? I got x to be 16.7 or something close and then put that back in to the original equation to get 65m
EDIT- i think i know now, i divided the coefficient of x by 12 twice.

yeah, you'll only have dropped one mark for that, just put it in wrong possibly

If you put 16.633... Back into the equation you got 120.something

You had to do 1944-1008 or -1008+1944 to get B as 936.
Could've sworn there wasn't any other x^2 terms. That 1944 rings a bell though. Oh well!

1/2(x^2)(120) is wrong because the area of a sector equations only work with radians. I think you have lost BOTH marks if you wrote JUST that. If you had stated the general formula and theta then you may get M1 but we're just speculating

If you multiply (1 + kx) by the x term you get another x^2 term!

That's weird because I got the c1 mark scheme the day of the exam, I don't mean the actual mark scheme I mean one a teacher has done
