Answer:

[tex]M^{2}=3.2[/tex]

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form [tex]y*x=k[/tex] or [tex]y=k/x[/tex]

In this problem we have

[tex]P*M^{2}=k[/tex]

step 1

Find the value of k

For P=8, M=2

substitute

[tex]k=(8)(2)^{2}=32[/tex]

The equation is equal to

[tex]P*M^{2}=32[/tex]

step 2

Find the value of M²

when P=10

substitute the value of P in the equation

[tex]10*M^{2}=32[/tex]

[tex]M^{2}=3.2[/tex]
