Question

if y varies inversely as the square of x, and when y = 4/63 find y when y varies inversely as the square of x = 3, and when find y when x=5

Answer 1

Explanation:

In order to solve this, we'll set up a proportion.

Since y is inversely related to the square of x, therefore:

y=4/63 ----->9 (square of x)

y=? ---------->25 (square of x)

According to the inverse relation:

y=4/63------->25

y=?------------->9 and y=4/175
