Question

Which is the quadratic variation equation for the relationship?

y varies directly with x2 and y = 72 when x = 3.

y = 8x 2

y = 24x 2

y = 1/8 x 2

y = 1/24x 2

Answer 1

u already know the equation
so replace x and y then solve or k

Answer 2

for*

Answer 3

72 = k3 squared

K=8

Did i do that right?

If so i think it would be the first one.

Answer 4

yes right square of 3 is 9
then divide both side by 9
u get 8 which is right and yes it is A :)
