Question

население страны ежегодно увеличивается на 5%.на сколько процентов увеличится население за 5 лет?

Answer 1

100% изначально населения

100+5%=105% будет через год

105+5%=110.25% будет через два года

110.25+5%=115.7625% будет через три года

115.7625+5%=121.550625% будет через четыре года

121.550625+5%=127.62815625% будет через пять лет

127.62815625-100=27.62815625% =27.6% приблизительно увеличится население через пять лет

Answer 2

Calculation of Population Increase

To calculate the percentage increase in population over a period of 5 years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where: - A is the final population after 5 years - P is the initial population - r is the annual growth rate (expressed as a decimal) - n is the number of times the growth is compounded per year - t is the number of years

In this case, the annual growth rate is 5% (0.05), and the population is compounded annually (n = 1). We want to calculate the increase in population after 5 years (t = 5).

Let's assume the initial population is 100.

A = 100(1 + 0.05/1)^(1*5)

Simplifying the equation:

A = 100(1.05)^5

Calculating the result:

A ≈ 128.04

Therefore, the population will increase by approximately 28.04% over a period of 5 years.

Please note that the actual population increase may vary depending on various factors and assumptions.
