The population of Columbus in 2015 was 840,000 people. In 2018 (three years later), The population grew to 972,405 people. Write

ra1l [238]

Answer:

N = I ( 1 + 50% )^t

Step-by-step explanation:

Given that The population of Columbus in 2015 was 840,000 people. In 2018 (three years later), The population grew to 972,405 people.

Write an exponential equations that models this situation.

From the question, the following parameters are given :

Initial number of population = 840,000

The new number of population = 972,405

The number of years = 3

Let the initial population = I

The new population = N

And the number of years = t

Since the population is increasing, the exponential equation can be written as

N = I ( 1 + R% )^t

Where R% is the percentage increase.

Solve for R

972405 = 840,000 ( 1 + R% )^3

972405/840000 = ( 1 + R% )^3

1.157625 = ( 1 + R% )^3

( 1 + R% ) = 1.05

Make R% the subject of formula

R% = 1.05 - 1

R% = 0.5

R = 0.5 × 100

R = 50%

Therefore, the exponential equations that models this situation can be expressed as:

N = I ( 1 + 50% )^t

Check the picture below.

recall that OM is an angle bisector, so those two "green" angles are equal, the same goes for ON which is also an angle bisector, those two "red" angles are also equal.

Ok so suppose the theory that if you add two sides of a triangle together it will be more than the remaining side but it has to work for all three sides so the two sides 10+8=18 so the number has to be less than 18 but the number also has to be more than 3 because 8+3=11 and 11 is larger than ten. the answer is
$3 \leqslant x \leqslant 17$
