Given that p is inversely proportional to the square of q that implies:
[tex]p\propto\frac{1}{q^2}[/tex]Remove the sign of proportionality and put a proportionality constant k such that:
[tex]p=\frac{k}{q^2}[/tex]Given that when q is 8 then p is 22. So,
[tex]22=\frac{k}{8^2}\Rightarrow k=22\times64=1408[/tex]Put k = 1408 and q = 4 in the equation to find the value of p:
[tex]p=\frac{1408}{4^2}=\frac{1408}{16}=88[/tex]Thus, the answer is 88.
