If y varies jointly with x cubed and the square root of z,
\n" ); document.write( "------------------
\n" ); document.write( "y = kx^3*sqrt(z)
\n" ); document.write( "---------
\n" ); document.write( "find the constant of variation if y=12 when x=4 and z=49
\n" ); document.write( "Solve for \"k\":
\n" ); document.write( "12 = k*4^3*sqrt(49)
\n" ); document.write( "----
\n" ); document.write( "12 = k*64*7
\n" ); document.write( "----
\n" ); document.write( "k = 0.0268
