Algebra.Com's Answer #261482 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! The height (t) in feet above the ground, of a ball thrown into the air from the top of a building is given by the function of h(t)= -16(t-2)^2+264, where t is the number of seconds the ball has been in the air. \n" ); document.write( "a. From what height was the ball thrown? \n" ); document.write( "b. what height does the ball reach? \n" ); document.write( "c. when does the ball strike the ground? \n" ); document.write( "e. for what values of t does the function have meaning? \n" ); document.write( "------------ \n" ); document.write( "I think h is the height, not t. \n" ); document.write( "h(t)= -16(t-2)^2+264 \n" ); document.write( "h(t) = -16t^2 + 64t + 200 \n" ); document.write( "--------------------- \n" ); document.write( "a. From what height was the ball thrown? \n" ); document.write( "200 feet \n" ); document.write( "b. what height does the ball reach? \n" ); document.write( "264 feet \n" ); document.write( "c. when does the ball strike the ground? \n" ); document.write( "When h = 0 \n" ); document.write( "-16t^2 + 64t + 200 = 0 \n" ); document.write( "t = 6.062 seconds \n" ); document.write( "e. for what values of t does the function have meaning? \n" ); document.write( "From launch to impact, t = 0 to t = 6.062 seconds \n" ); document.write( "Later than impact, the ball is stationary, h = 0. The meaning is a matter of opinion. \n" ); document.write( " \n" ); document.write( " |
