Answer
Constant of variation is
k = 1.35
We can write the variation equation by inserting k = 1.35
y = (k/x²)
y = (1.35/x²)
Step-by-step explanation
We are told that y varies inversely as the square of x, which can be written as
y ∝ (1/x²)
Introducing the constant of variation, k, we have
y ∝ (1/x²)
y = k(1/x²)
y = (k/x²)
We can then solve for k knowing that
y = 0.054 when x = 5
y = (k/x²)
0.054 = (k/5²)
(k/25) = 0.054
Multiply both sides by 25
(k/25) × 25 = 0.054 × 25
k = 1.35
Hope this Helps!!!
