x varies directly as the square of s and inversely as t.
\n" ); document.write( "x = k(s^2/t)
\n" ); document.write( "--------
\n" ); document.write( "How does x change when s is doubled?
\n" ); document.write( "If s is doubled you get:
\n" ); document.write( "x = k[(2s)^2/t]
\n" ); document.write( "x = k[4s^2/t]
\n" ); document.write( "x = 4k[s^2/t]
\n" ); document.write( "So, x is multiplied by 4 if s is toubled.
\n" ); document.write( "--------------\r
\n" ); document.write( "\n" ); document.write( "When both s and t are doubled?
\n" ); document.write( "x= k[(2s)^2/(2t)]
\n" ); document.write( "x=k[4s^2/2t]
\n" ); document.write( "x=k[2s^2/t]
\n" ); document.write( "x=2k[s^2/t]
\n" ); document.write( "So, s is multiplied by 2 if s and t are doubled.
\n" ); document.write( "=============
