Question

Which equation shows that z is directly proportion to the cube of x and inversely

proportional to the square of y?

Answer 1

z =
`(kx^3)/(y^2)`

Explanation:

Given that z is directly proportional to x³ and inversely proportional to y²

Then the equation relating them is

z =
`(kx^3)/(y^2)` ← k is the constant of proportionality
