In the year 2019, the population of a city is 20,612 people. The population increases at a rate of 1.8% per year. Based on this rate, during what year would the population of the city exceed 25,000 people?
2027
2029
2031
2032

B: 2029

Step-by-step explanation:

Interest Formula

A= amount

P= initial amount

r= rate/percentage

n= years

All we have to do is plug in the numbers from the word problem to get:

From here we solve for n:

Get the natural log (ln) of both sides:

n is approximately 10.823

n is the number of years it will take for the population to reach 25,000 people.

2019+10

=2029

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
