Answer:

x = 437.3 ft

Step-by-step explanation:

The angle at the top of the triangle = 90° - 29° = 61°

Using the sine ratio in the right triangle

sin61° = \frac{opposite}{hypotenuse} = \frac{x}{500}

Multiply both sides by 500

500 × sin61° = x, hence

x ≈ 437.3

Sedaia [141]

Answer:

y(x) = 0.0732x + 17.32

Step-by-step explanation:

The equation for the monthly charge has the following format

y(x) = ax + b

In which y(x) is the cost in function of the number of kilowatt-hours used(x), a is the price of each killowatt hour and b is the fixed(base) charge.

Base charge of $17.32 per month.

This means that b = 17.32

charge of 7.32 cents per kilowatt-hour

Our answer is in dollars. Each dollar is 100 cents. So 7.32 cents is a = 0.0732

Write an equation for the monthly charge y in terms of x, the number of kilowatt-hours used.

y(x) = ax + b

y(x) = 0.0732x + 17.32
