Question 747361: Find an equation of variation where y varies jointly as w and the square of x and inversely as z, and y=16 when w=5, x=4, and z=10 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Find an equation of variation where y varies jointly as w and the square of x and inversely as z, and y=16 when w=5, x=4, and z=10
--------
y = k*w*x^2/z
------
16 = k*5*16/10
160 = 80k
k = 2
------
Equation:
y = [2wx^2]/z
