Answer:

Concept:

Define Joint variation

Joint variation describes a situation where one variable depends on two (or more) other variables , and varies directly as each of them when the others are held constant. We say z varies jointly as x and y if. z=kxy. for some constant k.

Question:

Write the equation for the following: v varies jointly with x and the square of z.

This will be represented below as


\begin{gathered} v\propto xz^2 \\ v=kxz^2 \end{gathered}

Hence,

The final asnwer is


\Rightarrow v=kxz^2
