You can put this solution on YOUR website!
Basic model can be chosen \"y=ab%5Ex\"\r
\n" ); document.write( "\n" ); document.write( "Points (15,300) and (35,1600).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Not doing the entire solution but if you substitute into the model,....
\n" ); document.write( "\"b=%2816%2F3%29%5E%281%2F20%29\"
\n" ); document.write( "which is about \"b=1.0873\".
\n" ); document.write( "
