Assume you are throwing a baseball up from the top of a building. The equation for the height of the ball, h, at time, t, is represented by the equation: h=-16t^2+64t+512
\n" ); document.write( " After how many seconds does the ball reach 432 feet?
\n" ); document.write( "Solve:
\n" ); document.write( "-16t^2 + 64t + 512 = 432
\n" ); document.write( "------
\n" ); document.write( "16t^2 - 64t -80 = 0
\n" ); document.write( "------------------------
\n" ); document.write( "t^2 - 4t - 5 = 0
\n" ); document.write( "-----
\n" ); document.write( "(t-5)(t+1) = 0
\n" ); document.write( "Ans:: t = 5 seconds
\n" ); document.write( "----------------------
