Answer:
Step-by-step explanation:
If two quantities are inversely proportional, it means that an increase in the value of one variable would cause a corresponding decrease in the other variable and vice versa.
Given that M varies inversely as the square of P, if we introduce a constant of proportionality, k, the expression becomes
M = k/P²
If M = 9 when P = 2, then
9 = k/2² = k/4
k = 9 × 4 = 36
Therefore, the inverse variation equation is
M = 36/P²
When P = 3,
M = 36/3² = 36/9
M = 4
