You can put this solution on YOUR website!
I think you meant (please check)
\n" ); document.write( " $\"h=-16t%5E2%2B30t%2B6\"$
\n" ); document.write( ".
\n" ); document.write( "If so, finding the vertex gives you your solution.
\n" ); document.write( "Axis of symmetry = -b/2a
\n" ); document.write( "Axis of symmetry = -30/2(-16)
\n" ); document.write( "Axis of symmetry = -30/-32
\n" ); document.write( "Axis of symmetry = 15/16
\n" ); document.write( ".
\n" ); document.write( "Height, then when t = 15/16:
\n" ); document.write( " $\"h=-16%2815%2F16%29%5E2%2B30%2815%2F16%29%2B6\"$
\n" ); document.write( "h = 20.06 feet\r
\n" ); document.write( "
