Question and answer
Q: 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). If a
turbine generates 700kW in a 12 m/s wind, how much power does it generate in a 6 m/s wind? A. 1050kW B. 175kW C. 175kW D. 88kW
A: it generates B. 175kW in a 6 m/s wind.

User: The table shows the annual consumption of cheese per person in the United States for selected years in the 20th century. Let x = number of years since 1900, and y = pounds per person. What cubic model best fits this data? Year Pounds Consumed 1902 1.959 1924 6.373 1946 7.29 1982 15.817 A. y = 0.00989x3 - 0.0000872x2 + 1.192x + 0.403 B. y = -0.0000872x3 + 0.00989x2 - 0.403x - 1.192 C. y = -0.0000872x3 - 0.00989x2 - 0.403x + 1.192 D. y = 0.0000872x3 - 0.00989x2 + 0.403x + 1.192

Weegy: D. y = 0.0000872x3 - 0.00989x2 + 0.403x + 1.192 is the answer.
