Wind-Generated Power Wind farms are a source of renewable energy found around the world. The power P (in kilowatts) generated by a wind turbine varies directly as the cube of the wind speed v (in meters per second). The picture shows the power output of one turbine at one wind speed. To the nearest kilowatt, how much power does this turbine generate in a 10 m/s wind?
How is this problem like the direct variation you studied in Chapter 2?
With the direct variation,
The formula for P as a power function of v is
This turbine generates about 1172 kW of power in a 10 m/s wind.
Find all the real zeros of each function.
