You can put this solution on YOUR website!
x varies directly as the square of s and inversely as t.
\n" ); document.write( "---
\n" ); document.write( "x = k[s^2/t]
\n" ); document.write( "--------------------\r
\n" ); document.write( "\n" ); document.write( "How does x change when s is doubled?
\n" ); document.write( "Change from s to 2s to get:\r
\n" ); document.write( "\n" ); document.write( "x = k[(2s)^2/t] = k[4s^2/t] = 4[k[s^2/t]]
\n" ); document.write( "From this you can see that the value of x is multiplied by 4.
\n" ); document.write( "--------------------------------------------------------------------\r
\n" ); document.write( "\n" ); document.write( "When both s and t are doubled?)))
\n" ); document.write( "Change s to 2s and change t to 2t to get:\r
\n" ); document.write( "\n" ); document.write( "x = k[(2s)^2/(2t)] = k[4s^2/2t] = k[2s^2/t] = 2[k[s^2/t]]
\n" ); document.write( "From this you can see that the value of x is multiplied by 2.\r
