y varies directly as x and inversely as the square of z.
\n" ); document.write( "---
\n" ); document.write( "y = kx/z^2
\n" ); document.write( "Solve for \"k\" using the following:\r
\n" ); document.write( "\n" ); document.write( "y=96 when x=64 and z=4.
\n" ); document.write( "96 = k*64/4^2
\n" ); document.write( "96 = 4k
\n" ); document.write( "k = 24
\n" ); document.write( "---
\n" ); document.write( "Equation for this Problem:
\n" ); document.write( "y = 24*x/z^2
\n" ); document.write( "----\r
\n" ); document.write( "\n" ); document.write( "Find y when x=75 and z=5.
\n" ); document.write( "y = 24*75/5^2
\n" ); document.write( "y = 24*3
\n" ); document.write( "y = 72
