vfiekz [6]

Answer:the output for a wind speed of 40 miles per hour is 810.8 kilowatts.

Step-by-step explanation:

The power P produced by a wind turbine is directly proportional to the cube of the wind speed S. This means that

P is directly proportional to S

Introducing a constant of proportionality, k, it becomes

P = kS

A wind speed of 37 miles per hour produces a power output of 750 kilowatts. This means that

750 = k × 37

k = 750/37 = 20.27

The expression becomes

P = 20.27S

Therefore, the output for a wind speed of 40 miles per hour would be

P = 20.27 × 40

P = 810.8

Answer:

y² + 8y + 16

Step-by-step explanation:

Given

(y + 4)²

= (y + 4)(y + 4)

Each term in the second parenthesis is multiplied by each term in the first parenthesis, that is

y(y + 4) + 4(y + 4) ← distribute both parenthesis

= y² + 4y + 4y + 16 ← collect like terms

= y² + 8y + 16
