Country a and country b currently have the same population but the population of country a is growing at a rate of 5% per year but the population of country b is growing at a rate of 21.551% per year. what expression represents the ratio, when converted to a decimal, of country a's population to country b's population after x years? (1.05^4=1.21551)

Step-by-step explanation:

Let the initial  population of country A represented by and the population of country B is represented by ,

Then, According to the question,

----------(1)

Since, the population of country A is increasing at a rate of 5% per year,

Hence, the population of A after x years

Similarly,  the population of country B is increasing at a rate of 21.551 % per year,

Hence, the population of B after x years

Thus, the ratio of the population of A and that of B is,

By equation (1),

Which is the required function.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
