The constant of variation, k = 0.57
We are given that z varies jointly as the second power of x (x²), and the third power of y (y³).
For a constant of variation, k, z can be written as
z = x²y³k.
We are also given
z = 31.5
x = 2
x = 2.4
31.5 = (2²) (2.4) ³k
31.5 = 4*13.824k
31.5 = 55.296k
k = 31.5/55.296
