Answer:
.173 seconds or a negataive
Step-by-step explanation:
Your formula would be
h = -16t^2 - 55t + 10
when it hits the ground h = 0
16t^2 + 55t - 10 = 0
t = (-55 ± √3665)/32 = .173 seconds or a negataive
Step-by-step explanation:
h(x)=5-7x²
h(-1)=5-7×(-1)²

Answer:
38.2842 m
Step-by-step explanation:
The acceleration is given by ...
a = ∆v/∆t
and the distance traveled is given by ...
d = 1/2at^2
So the distance we're looking for is ...
d = (1/2)(21.0366 m/s)/(8.06 s)(5.41632 s)^2 = 32.2842 m
Answer:
65
Step-by-step explanation:
35+40+27+42+45+50=249 249+65=315 315/7=45
