Question

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

ş, when x is
?

Answer 1

y =
`(27)/(x^2)`

Explanation:

Assuming you require the equation of proportion.

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

y =
`(k)/(x^2)`

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

3 =
`(k)/(3^2)` =
`(k)/(9)` ( multiply both sides by 9 )

27 = k

y =
`(27)/(x^2)` ← equation of proportion

Answer 2

It will be same the value of second Y
