Dear Gunner,
Answer for
17(a)(i)
Answer for 17
(a)(ii)
y =kx^n -----------------------
(1) y
=kx^n ----------------------- (1)
A = (pi)
r^2
Time = Distance/Speed
Since are A = y, radius r =
x
Since Time = y and Distance = x
So, y = (pi) x^2 --------------
(2)
So, y = x^1/Speed ------------ (2)
By comparison eqns (1) &
(2)
By comparison eqns (1) & (2)
n =
2
n = 1
