Suppose z varies directly with x and inversely with the square of y.
\n" ); document.write( "---
\n" ); document.write( "z = kx/y^2
\n" ); document.write( "----
\n" ); document.write( "Find \"k\": using the following information.
\n" ); document.write( "When x=5 and Y= 9,z= 900.
\n" ); document.write( "---
\n" ); document.write( "900 = k*5/9^2
\n" ); document.write( "k= 900*81/5 = 14580
\n" ); document.write( "------------------------
\n" ); document.write( "Find the equation of variation.
\n" ); document.write( "Equation:
\n" ); document.write( "y = 14580x/y^2
