Question

Y is inversely proportional to the square of x. If Y = 3 when x = 3, then Y =

Answer 1

Answer:

It will be same the value of second Y

Answer 2

Answer:

y = $\frac{27}{x^2}$

Step-by-step explanation:

Assuming you require the equation of proportion.

Given y is inversely proportional to x² , then the equation relating them is

y = $\frac{k}{x^2}$

To find k use the condition if y = 3, then x = 3, that is

3 = $\frac{k}{3^2}$ = $\frac{k}{9}$ ( multiply both sides by 9 )

27 = k

y = $\frac{27}{x^2}$ ← equation of proportion
