Question

The square of y varies directly as the cube of x. when x = 4, y = 2. which equation can be used to find other combinations of x and y?

Answer 1

The equation can be used to find other combinations of x and y is  y^2 = (1/16)x^3

How to determine the equation?

The direct variation from the square of y to the cube of x is represented as:

y^2 = kx^3

Where k represents the variation constant.

When x = 4, y = 2.

So, we have:

2^2 = k * 4^3

This gives

4 = 64k

Divide both sides by 64

k = 1/16

Substitute k = 1/16 in y^2 = kx^3

y^2 = (1/16)x^3

Hence, the equation can be used to find other combinations of x and y is  y^2 = (1/16)x^3
