South Korea (population 50 million) fears that its native population may be extinct by the year 2750. What is the best estimate

Anvisha [2.4K]

Answer:

b)-2.4% year

Explanation:

The population growth can be calculated by the following equation.

$P(t) = P(0)e^{rt}$

In which $P(t)$ is the population in t years from now, $P(0)$ is the population in the current year and r(decimal) is the growth rate. $e = 2.71$ is the Euler number.

The current population of South Korea is 50 million, so $P(0) = 50,000,000$

2750 is 2750 - 2019 is 731 years from now. So we have that $t = 731$ . The population is going to be extinct, so $P(731) = 0$ .

So, we can replace the values of $P(0)$ and t in the equation, and see for which growth rate $P(731) = 0$ .

a) 0.012 % year

This is a positive growth rate, which means that the population will not be going extinct. So this is not the alternative

b)-2.4% year

$r = -0.024$

$P(t) = P(0)e^{rt}$

$P(731) = 50,000,000e^{-0.024*731} = 1.20$

Population of 1 person, basically extinct. This is the correct answer

c)-0.01% year'

$r = -0.001$

$P(t) = P(0)e^{rt}$

$P(731) = 50,000,000e^{-0.001*731} = 24,071,366$

Population still at 24 million, it does not goes extinct.

d)-0.012% year

$r = -0.0012$

$P(t) = P(0)e^{rt}$

$P(731) = 50,000,000e^{-0.0012*731} = 20,797,296$

Population still at almost 21 million, it does not goes extinct.
