Question

Find the constant variation and the variation equation if y varies jointly as x and w and inversely as the square of z, and y =150 when w=9, x=15, and z =0.3.

Answer 1

AHHHHHH!!!!!

Answer 2

\[\Large y=\frac{k*x*w}{z}\]

Answer 3

y= (a)xw/z^2
when y =150 w=9, x=15, and z =0.3.
a= 10

Answer 4

k= ???
