document.write( "Question 207888: If a ball is thrown upwards at 40 feet per second from a rooftop 24 feet above the ground, then its height above the ground t seconds after it is thrown is given by h = - 16 t2 + 40 t + 24. \r
\n" ); document.write( "\n" ); document.write( "a. Rewrite the above formula with the polynomial on the right hand side factored completely.

You can put this solution on YOUR website!
\"h+=+-+16+t%5E2+%2B+40+t+%2B+24\"
\n" ); document.write( "\"h+=+-8%2A%282t%5E2+-+5t+-+3%29\"
\n" ); document.write( "\"h+=+-8%2A%282t%2B1%29%28t-3%29\"\r
\n" ); document.write( "\n" ); document.write( "You can see that at t=3, the term (t-3) above would evaluate to 0.
\n" ); document.write( "Since 0* anything = 0, then h(3) = 0.
\n" ); document.write( "
