The value of y varies inversely as the square of x, and y = 16, when x = 3.
irina [24]

Answer:

The answer is

<h2>12</h2>

Step-by-step explanation:

The above variation is written as

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

where k is the constant of variation

when y = 16

x = 3

k = yx²

k = 16(3)²

k = 16 × 9

k = 144

The formula for the variation is

y =  \frac{144}{ {x}^{2} }

when y = 1

We have

1 =  \frac{144}{ {x}^{2} }

Cross multiply

x² = 144

Find the square root of both sides

x = √144

x = 12

Hope this helps you
