Question 968394: Find an equation of variation where y varies jointly as x and the square of z and inversely as w, and y=100 when x=0.1, z=10 and w=5. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Find an equation of variation where y varies jointly as x and the square of z and inversely as w, and y=100 when x=0.1, z=10 and w=5.
-----------------
y = k*x*z^2/w
-------
Solve for "y"::
100 = k*0.1*100/5
-----
500 = 10k
k = 50
--------
Equation:
y = 50*x*z^2/w
