Suppose the polynomial function below represents the power generated by a wind turbine, where x represents the wind speed in met
Elis [28]

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,

f(x) = 0.08x^3 + x^2 + x + 0.26

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,

=f(10)

= 0.08(10)^3 + (10)^2 + (10) + 0.26

= 0.08(1000) + (100) + (10) + 0.26

= 80 + 100 + 10 + 0.26

=190.26

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

Find the inverse of the relation. Use proper notation. {(8,−1),(−8,−1),(−2,−8),(2,8)} please help!!
tiny-mole [99]

Answer: The inverse relation is { (-1, -8), (-1, -8), (-8, -2), (8, 2) }

The inverse is effectively the opposite of the original relation. It undoes what the original relation does. So we'll swap the x and y values for each given point in the form (x,y). Something like (8,-1) becomes (-1,8). The other points follow the same pattern as well.
