At a resort, tourists watch swimmers dive from a cliff to the water 144 feet below.
\n" ); document.write( " A diver's height h above the water t seconds after diving is given by
\n" ); document.write( "h = −16t2 + 144.
\n" ); document.write( " How long does a dive last?
\n" ); document.write( "height of the water is 0
\n" ); document.write( " $\"-16t%5E2+%2B+144+=+0\"$
\n" ); document.write( " $\"-16t%5E2+=+-144+\"$
\n" ); document.write( " $\"t%5E2+=+%28-144%29%2F%28-16%29\"$
\n" ); document.write( " $\"t%5E2+=+%2B9\"$
\n" ); document.write( "t = $\"sqrt%289%29\"$
\n" ); document.write( "t = 3 seconds \n" ); document.write( "
