Answer: 
Step-by-step explanation:
1. You have the following information given in the problem:
- The distance to the nearest exit door is no more than 150 feet.
-
represents the distance to the nearest exit door, in feet.
2. Therefore, keeping the information above on mind, you know that the distance to the nearest exit door (
) must be less than or equal to 150 feet, then, you can express this as following:

Center: (-5,-6)
Radius: 39

This is the form of a circle. Use this form to determine the center and radius of the circle.
Consecutive terms in an arithmetic sequence differ by a constant

. So



Denote the

-th term in the sequence by

. Now that

, we have

which means
Ten thousand I believe let me know if wrong that’s what my math got
Pretty sure it’s y= 5 + 1.95x
I don’t think that the number of people matters because the cost doesn’t vary based on the number of people
