The population of a city in 2000 was 18,500 people. Since then the population has increased 4.8% every year. Determine the correct equation that would represent what the population would be in the year 2028.

Answers

Answer:

see below

Step-by-step explanation:

Consider the year 2000 to be year 0. This would make year 2028 year 8.

Population growth or decay function: [tex]A = Pe^{rt}[/tex]

where A is the final amount, P is the principal amount, r is the rate, and t is time.

[tex]A = 18,500e^{(0.048)(8)}[/tex]

This can be simplified to

[tex]A = 18,500e^{0.384}[/tex]

Hopefully this is what the question is asking!

The angles are adjacent because they are next to each other adding to 90 degrees.

How do we find x?

Angle 1 + Angle 2 = 90°

31° + (10x - 1)° = 90°

10x + 30 = 90°

10x = 90° - 30

10x = 60°

x = 60°/10

x = 6

Answer: Adjacent and x = 6.
