You can put this solution on YOUR website!
a) how high does the ball get
\n" ); document.write( "What is the largest or biggest h(t) and for what value of t?\r
\n" ); document.write( "\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( "b) when does it reach that height?
\n" ); document.write( "For what value of t is h(t) the largest?\r
\n" ); document.write( "\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( "c) how high is the ball after 4 seconds?
\n" ); document.write( "What is h(4)?\r
\n" ); document.write( "\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( "d) when will the ball hit the ground?
\n" ); document.write( "One of the roots or zeros of h.\r
\n" ); document.write( "\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( "e) when does the ball reach 100 ft?
\n" ); document.write( "Let h(t)=100 and solve for t.
\n" ); document.write( "
\n" );
