Answer:
x = 12
Explanation:
The statement
The value of y varies inversely as the square of x is written as

where k is the constant of proportionality
To find the value of x when y = 1 first find the formula for the variation
y = 16 x = 3
k = yx²
k = 16(3)²
k = 16 × 9
k = 144
The formula for the variation is

when y = 1
We have

Cross multiply
x² = 144
Find the square root of both sides
We have the final answer as
x = 12
