Answer:
z = 0.9778x^2 / y.
Step-by-step explanation:
When z varies with the square of x the equation is z = kx^2 where k = a constant.
If it also varies inversely with y the equation is z = kx^2/y.
When z = 4.4 , x = 3 and y = 2 we have:-
4.4 = k * 3^2 / 2
Multiplying by 2:
8.8 = 9k
k = 8.8 / 9
= 0.9778.
So the required formula is z = 0.9778x^2 / y.
