The population of a particular country was 23 million in 1982; in 1995, it was 33 million. Theexponential growth function A =23ekt describes the population of this country t years after 1982.Use the fact that 13 years after 1982 the population increased by 10 million to find k to threedecimal places.

The value of k is 0.448.

Step-by-step explanation:

Given the exponential growth function is

A= The population of the country

k= growth rate.

The population of the country increased by 10 million in 13 years after 1982.

Then the population is =(23+13)million = 36 million.

Here,

A= 36 million, t= 13

Taking ln function both sides

The value of k is 0.448.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
