y varies directly as the cube of x and inversely as the square of z.

If y is 30 when x is 2 and z is 4:

b) Find the equation that models this data.



c) Find the value of y when x is 3 and z is 2.

  • Intermediate Algebra -

    y = kx^3/z^2 -->y varies directly as the cube of x and inversely as the square of z.
