Answer:
<em>f(10) or the power generated by the wind turbine at the wind speed of 10 m/s is </em><em>190.26 kW</em>
Step-by-step explanation:
The given polynomial function is,

where,
x represents the wind speed in meters per second,
y represents the kilowatts generated.
Putting x=10, we can get the value of f(10).
So,





Therefore,at x=10 or when the wind speed is 10 m/s, then y or the power generated by the wind turbine will be 190.26 kW

Answer:
10,38,43
Step-by-step explanation:
n+4n-2+5n-7=91
10n=91+2+7
10n=100
n=10
4(10)-2=38
5(10)-7=43
