The value of y varies inversely as x^2 and when x = 24, y = 15

 

this means    y = k/x^2       where k is proportionality constant

                       or    y x^2  = k        now when x = 24    y = 15

                              15 (24^2)  = 8640

 

 

now when y = 13            13 (x^2) = 8640    solve for 'x'  value(s)
