T varies directly as the square root of p and inversely as the square of g. This joint variation can be written as

• $T\propto pg$

• $T\propto\frac{p}{\sqrt{g}}$

• $T\propto\frac{p}{g}$

• $T\propto\frac{\sqrt{p}}{g^2}$

P varies directly to the cube root of X and inversely as Y. Given that the constant is k, find the relation between P, X and Y.

• $P=\frac{kX^3}{Y}$

• $P=\frac{kX^{\frac{1}{3}}}{Y}$

• $P=kX^{\frac{1}{3}}Y$

• $P=\frac{kY^3}{X}$

State what type of variation the equation represents.

• Direct

• Inverse

• Joint

• None
