Solve for the value of the consant of variation k, and then find the missing value.

1.)z varies jointly as the square root of the product of x and y, if z=3 when x=3 and y=12, find x when z=6 and y=64

2.)d varies jointly as h and g. if d=15 when h=14 and g=5, find g when h=21 and h=8.

3) q varies jointly as r and s. if q=2.4, when r=0.6 and s=0.8, find q when r=1.6 and s=.01
