Question

The cube root of rvaries inversely with the square of s. Which two equations model this relationship

Answer 1

3√r = k/s²

s²r^1/3 = k

Explanation:

Cube root of r = 3√r

Square of s = s²

cube root of r varies inversely with the square of s

3√r = k/s²

Cross product

3√r * s² = k

s²r^1/3 = k

Note:

r^1/3

= 3√r
