Well, £2 is 200p, so it's like saying what fraction of 200 is 20, which is 1/10. So the answer is 1/10, hope this helped!
d.
Given : p(x) = x⁵
p(-x) = (-x)⁵
p(-x) = (-1)⁵(x)⁵
p(-x) = -(x)⁵
0.5p(-x) = -0.5(x)⁵
0.5p(-x) + 4 = -0.5(x)⁵ + 4
m(x) = -0.5(x)⁵ + 4
e.
Given : p(x) = x⁴
p(0.5x) = (0.5x)⁴
p(0.5x) = (0.5)⁴(x)⁴
-p(0.5x) = -(0.5)⁴(x)⁴
-p(0.5x) + 2 = -(0.5)⁴(x)⁴ + 2
m(x) = -(0.5)⁴(x)⁴ + 2
First we need to see the pythagorean formula which is

Substituting the given values of a,b , we will get




And

So we have

So the given triangle is a right triangle .
I would say a line graph because it is visually easiest to see any dips or rises in income for each month of the year.
