Height of a ball. If a ball is thrown straight upward at
\n" ); document.write( "40 feet per second from a rooftop 24 feet above the
\n" ); document.write( "ground, then its height in feet above the ground t seconds
\n" ); document.write( "after it is thrown is given by
\n" ); document.write( "h(t)= 16t^2 + 40t + 24.
\n" ); document.write( "a) Find
\n" ); document.write( " h(0) = 24
\n" ); document.write( " h(1) = -16 + 40 + 24 = 48
\n" ); document.write( " h(2) = -64 + 80 + 24 = 60
\n" ); document.write( " h(3) = -144 + 120 + 24 = 0
\n" ); document.write( "------------------------------------
\n" ); document.write( "b) Rewrite the formula with the polynomial factored
\n" ); document.write( "completely.
\n" ); document.write( "h(t) = (-8)(2t^2 - 5t -3)
\n" ); document.write( "h(t) = -8[2t^2 -6t + t - 3]
\n" ); document.write( "h(t) = -8[2t(t-3)+(t-3)]
\n" ); document.write( "h(t) = -8(t-3)(2t+1)
\n" ); document.write( "-------------------------------
\n" ); document.write( "c) Find h(3) using the result of part (b).
\n" ); document.write( "h(3) = -8(0)(7) = 0
