Question

A quantity x varies inversely as the square of y . Obtain that x =4 when y =3, the value of x when y =6 is ...........

Answer 1

Answer:

x = 1

Step-by-step explanation:

x varies inversely as the square of y

x = k/y²

When x = 4, y = 3

4 = k/3²

4 = k/9

k = 36

The equation is:

x = 36/y²

When y = 6

x = 36/6²

x = 36/36

x = 1

Answer: x = 1
