Answer:
4
Step-by-step explanation:
When M varies inversely P squared rhen this is represented as
[tex]M=\frac {k}{P^{2}}[/tex]
Here, k is a constant of proportionality
Now when M is 9 and P is 2, P squared will be 4. Now substituting the value of P squared and M into the equation we can find the xonstant of proportionality as
K=9*4=36
Now that we have k, when P is 3 then we substitute the value of P as 3 and k as 36 into the first equation hence
[tex]M=\frac {36}{3^{2}}=4[/tex]
Therefore, M=4
