Complete the square,
\n" ); document.write( " $\"x%5E2-14x%2By%5E2-150y=-49\"$
\n" ); document.write( " $\"%28x%5E2-14x%2B49%29%2B%28y%5E2-150%2B5625%29=-49%2B49%2B5625\"$
\n" ); document.write( " $\"%28x-7%29%5E2%2B%28y-75%29%5E2=5625\"$
\n" ); document.write( "So the circle is centered at ( $\"7\"$ , $\"75\"$ ) and has a radius of $\"R=sqrt%285625%29=75\"$ .
\n" ); document.write( "The assumption is that $\"y=0\"$ is the ground.
\n" ); document.write( "THe maximum height is then $\"y%5Bmax%5D=2R=150\"$ $\"ft\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
