The variation equation in the scenario is y = 25/√x
How to determine the variation equation?
The variation statement is given as:
y varies inversely with x sqr(x)
Inverse variations are represented as:
y = k/√x
Where k represents the constant of variation/proportionality
When y = 5, x = 25
So, we have:
5 = k/√25
Evaluate the exponent
5 = k/5
Multiply by 5
k = 25
Substitute k = 25 in y = k/√x
y = 25/√x
Hence, the variation equation is y = 25/√x
