I think it is -3/4 im pretty sure
Answer:
D)
Step-by-step explanation:
Every tenth person will get it no matter what, every time. The order will not change.
Log(66)
log(6 × 11)
log(6) + log(11)
Initial velocity of the plane is Vo = 0.
acceleration a = 1.3 m/s2
total distance = 2.5 km = 2500m
time taken to reach 2.5 km with 1.3m/s^2 acceleration = t
S = Vo t + 0.5 a t^2
2500 = 0 + (0.5*1.3* t^2)
t^2 = 3846.15
t = 62 s
the maximum velocity plan can reach within 62 s is Vt
Vt = Vo + a t
Vt = 0 + (1.3*62)
Vt = 80.6 m/s
Since 80.6 m/s is greater than 75 m/s, plane can use this runway to takeoff with required speed.
The independent variable (the one they want) is the # of hours worked, since that determines the price.
