Answer:the output for a wind speed of 40 miles per hour is 810.8 kilowatts.
Step-by-step explanation:
The power P produced by a wind turbine is directly proportional to the cube of the wind speed S. This means that
P is directly proportional to S
Introducing a constant of proportionality, k, it becomes
P = kS
A wind speed of 37 miles per hour produces a power output of 750 kilowatts. This means that
750 = k × 37
k = 750/37 = 20.27
The expression becomes
P = 20.27S
Therefore, the output for a wind speed of 40 miles per hour would be
P = 20.27 × 40
P = 810.8

Answer:
78.4 is your answer, if you dont round it
Step-by-step explanation:
take 98 and multiply it by .80. And you can also subtract 98 from 78 if you want
The answer is 65. Because if you use the discriminant formula which is b^2 - 4(a)(c)
