Answer:
y = 208
Step-by-step explanation:
We need to solve this problem, we need to interpret the question
y varies inversely means 1/
y varies inversely with the square of x
That's y varies /x^2
To equate it, we need to add a constant K
y = K * 1/x^2
y = K/x^2
As we've been provided with some information
y = 13
x = 2
Inserting into
y = K/x^2
13 = K/2^2
13 = K/4
K = 13 * 4
K = 52
Our constant is 52
Provided on the another information we are given to find y, x = 0.25
Using the same formula
y = K/x^2
K = 52
x = 0.25
y = 52/0.25
y = 208
The new value of y is 208 when x = 0.25
