The quantity q varies inversely with the square of m and directly with the product of r and x. when q is 2.5, mis 4 and the
product of r and x is 8. what is the constant of variation?

The constant of proportionality is 5.

Step-by-step explanation:

If the quantity q varies inversely with the square of m and directly with the product of r and x, then the variation equation is

When q=2.5, m= 4 and the

product of rx = 8.

We plug in this values to get;

Multiply both sides by 2

The constant of proportionality is 5.
