Suppose that z varies jointly with x and y.
Find the constant of proportionality k if z = 455 when y = 5 and x = 14.
k=
Using the k from above write the variation equation in terms of x and y.
z=
Using the k from above find z given that y = 26 and x = 38.
z=
If needed, round answer to 3 decimal places.
