Find an equation of variation where y varies inversely as the square of x, and where y = 0.35 when x = 0.1.

**Solution:-**

Since y = varies inversely as the square of x, use the form

y = .

To find the variation constant, substitute 0.1 for x and 0.35 for y.

y = .

0.35 = y = .

Simplify the exponential expression.

.035 =

Solve for k.

0.0035 = k

The variation constant is 0.0035.

The equation of variation is y = .
