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:
t = (m / g) * p
Step-by-step explanation:
Since we are given a variable for every part of the equation that we need we can go ahead and create the following equation where t equals the total cost
t = (m / g) * p
In this equation, we need to first divide the total number of miles by the number of miles that the car gets per gallon. This would give us the total number of gallons that the car would use during the entire trip. We then multiply the number of gallons by the price per gallon to get the final cost of the entire trip.
Answer:d=0.8x+1
Step-by-step explanation:
To solve 0.5(2d-6)=0.2(4x-10)
Open the brackets
We get
d-3=0.8x-2
To make d the subject of formular
d=0.8x-2+3
d=0.8x+1
I think that the length's area is 6075
