The speed of the jet stream is 4.55 miles per hour
Step-by-step explanation:
Distance of one way trip= 3000 miles
The total distance of the round trip= 6000 miles
Total time = 11 hrs
Speed of the plane = 550 miles per hr
Speed = distance/time
= 6000/11
= 545.45 miles per hour
Speed of the plane = 545.45 + speed of the jet stream
550 = 545.45 + speed of jet stream
Speed of jet stream = 4.55 miles per hour
The speed of the jet stream is 4.55 miles per hour

Answer:
a. 0.81
b. v = 28000(0.81^n)
c. 2757.36
Step-by-step explanation:
a. The growth factor is 1 more than the growth rate. Here, the growth rate is -19% (per year), so the growth factor, the multiplier, is ...
1 -0.19 = 0.81
__
b. The equation sets value equal to the original value multiplied by the growth factor to the power of the number of years:
value = (original value) × (growth factor)^n
v = 28000(0.81^n)
__
c. For n=11, this is ...
v = 28000(0.81^11) ≈ 2757.36
The value of the truck after 11 years is about $2757.
