Q7 b
Q11 - Can anyone explain how to get the answer  ???
q18 b

Thx

-Cornea:
listen when u do f(x) u remove the X and replace it by the number given
now it's f^-1(x) so replace the y by 1 instead of replacing x because it's inverse
so it will be:
1=10^x
Anything to the power of zero =1
so x =0

listen u just need to find the perimeter of the shape
4*4 i.e(4+4+4+4) +2*pie*1.2 i.e(4*0.25*2*pie*1.2)
i guess the answer will be 23.5 approximatly it's 24 ppl (or if u want to add this half person :P)
