PLEASE HELP!!!!!! MEDAL TO RIGHT ANSWER! Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. A rocket is launched from atop a 76-foot cliff with an initial velocity of 135 ft/s. A.) Substitute the values into the vertical motion formula h=-16t^2+vt+c. Let h=0 B.) Use the quadratic formula find out how long the rocket will take to hit the ground after it is launched. Round to the nearest tenth of a second. 1.)0= -16t^2 + 135t + 76; 0.5 s 2.)0= -16t^2 + 135t + 76; 9 s

okay i can do this quickly h=0 v=135 and c=76
and b just wants you to slove for t
I think its answer #1 i just want someone to check it
okay 1sec
actually its 2
you should get two answers -0.5 and 8.9 but time cant be negative so it must be 8.9
true thanks!
no prob bye!
