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

How do I solve for y?

vivado [14]

Short Answer: y = 36°
Remark
What an interesting question!! The first thing you have to do is find out what the interior angle of a regular pentagon is. After you have done that, you can calculate y.

Method.
The exterior angles of a regular figure add up to 360°.

Step One
Find out the size of the exterior angles of a regular pentagon.
There are 5 such angles. They add up to 360°

5x = 360 Divide by 5
x = 360 / 5
x = 72°

Step Two
Find out the value of the interior angles of a pentagon.

Method
The interior and exterior angles add up to 180°
Exterior Angle + Interior Angle = 180°
Exterior angle = 72 degrees
72° + Interior Angle = 180° Subtract 72 from both sides.
Interior Angle = 180° - 72°
Interior Angle = 108°

Step Three
Solve for y.

There are 3 tiles each with an angle of 108° that are placed together. So y + 3 interior angles = 360°

y + 3*interior angles = 360°
y + 3*108 = 360
y + 324 = 360 Subtract 324 from both sides.
y = 360 - 324
y = 36°
