Answer:
28,130
Step-by-step explanation:
18,942+9188=28,130
So, here we have an exponential function.
Remember that an exponential function has the form:

Where a represents an initial amount, and r is the rate of this amount to change. (Increase, or decrease).
So, given that the population of City A in 2000 was 40 thousand people and the population increased by 13% each year, we can say that

So,

For city B:

But something different happens with city C. This is not an exponential function, this is a linear function.
So,

The formula of a distance between two points:

We have the points (-1, 8) and (5, -2). Substitute:

Answer:
8
Step-by-step explanation:
50 is at rank 8.5, but since its a 53% chance. it would be below the .5 area and round to 8
