If we have the expression $\frac{b}{7}$ , substitute 14 for b to simplify.

$\frac{b}{7}$ → $\frac{14}{7}$ → 2

The complete simplified expression is 2.

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

Elis [28]

Answer:

f(10) or the power generated by the wind turbine at the wind speed of 10 m/s is 190.26 kW

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

URGENT PLEASE HELP 45 POINTS! Complete this activity. Given: f(x) = x + 2 [f(x)] 2 =

ivanzaharov [21]

We are told that f(x) = x + 2. We want to find $(f(x))^{2}$ .

Squaring f(x) on one side means we square x + 2 on the other.

So,

f(x) = x + 2

(f(x))² = (x + 2)²

= (x + 2)(x + 2)

We can use FOIL to square x + 2. The first terms multiply to x², the outside terms to 2x, the inside terms to 2x and the last terms to 4.

= x² + 2x + 2x + 4

= x² + 4x + 4

So [f(x)]² = x² + 4x + 4
