The equation given that the statement

Expert Solution

Answer to Problem 16E

The equation is A=kxy

Explanation of Solution

Given:

  A is jointly proportional to xy

Concept used:

If the quantities x , y and z are related by an equation

  z=kxy

Where k is nonzero constant

That is z varies jointly as x or z isjointly proportional to xandy

The constant k is called constant proportionality

Calculation:

If the quantities A,x and y are related by an equation

  Aαxy

  A=kxy

For some constant k0

That is A varies jointly as xy or A is jointly proportional to xy

The constant k is called constant proportionality
