A supermarket offers a delivery service. If a customer pays $9 per month, each delivery costs just $2. Write an equation that sh
1 answer:
The linear function that models the total cost for x deliveries is:
-------------------
A linear function has the following format:
In which
- m is the slope, that is, the rate of change.
- b is the y-intercept, that is, the value of y when x = 0.
In this problem:
- Fixed cost of $9 per month,
.
- Cost of $2 for each delivery, thus
.
The function for the <u>total cost for x deliveries is:</u>

Answer:
108°
Step-by-step explanation:
Suppose that circle with center A is a circular arena. Points B, C, D, E and F are 5 lights. These 5 points form regular pentagon (because these 5 lights are equally spaced around the perimeter of the arena).
The sum of all interior angles of pentagon can be calculated using following formula
All interior angles in regular pentagon are of equal measure, so
Thus, the measure of each angle formed by the lights on the perimeter is 108°.
