H=-16t^2+56t+1, the airplane is shot up from a platform 1 foot above the ground, so 1= - 16t^2+56t+1, we solve this equation
(- 16t+56)t=0, (- 16t+56)=0 or t=o, - 16t+56=0, implies t =3.5s
so the answer is C)3.5 seconds
Answer:
Step-by-step e[xplanation:
[-1.00 (3.99 x 4)] / 2=
3.99 x 4 = 15.96
15.96 - 1.00 = 14.96
14.96 / 2 = $ 7.48
I think answer should be 8 please give me brainlest let me know if it’s correct or not okay thanks bye
