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

If f(x) =x-3 then find f^-1 (x)

Pepsi [2]

Answer: x+3

The original function tells us to subtract 3 from the input x.

The inverse function will do the exact opposite: it adds 3 to the input x.

How do I solve this? It says find the value of x, then find the angle measures of the polygon.

Anni [7]

180 = 65 + (x-5) + x
-65 -65

115 = x - 5 + x

115 = 2x - 5

2x = 120

x = 60

The angle measures are 65, 60, and 55 degrees.
