You can put this solution on YOUR website!
y=kx^(5/2)
\n" ); document.write( "58.6=k*19.4^(5/2)
\n" ); document.write( "k=58.6/19.4^(5/2)=0.0354
\n" ); document.write( "-----------
\n" ); document.write( "y=(0.0354)x^(5/2)
\n" ); document.write( "when x=26.2, y=124.38; 3 sig digits 124
\n" ); document.write( "when x=83.6, y=2470.57 3 sig digits 2470
\n" ); document.write( "
\n" );
