Use an annual growth rate of 1.6% in a 40 year period for a certain population to find the approximate doubling time and then predict the population in 2050, based on a 2000 population of 6.0 billion. What is the approximate doubling time? What will be the approximate population in 2050?

- the approximate doubling time is 43.3216 ≈ 43

- the approximate population in 2050 is 13.353 billions

Step-by-step explanation:

Given that;

growth rate r = 1.6% = 0.016

so,

Doubling time = In2 / 0.016 = 43.3216

Hence, the approximate doubling time is 43.3216 ≈ 43

Population in 2050;

t = 2050 - 2000 = 50

po = 6 billion

r = 0.016

so

p = po

we substitute

p = 6

p = 6

p = 6( 2.2255 )

p = 13.353 billions

Therefore, the approximate population in 2050 is 13.353 billions

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

the correct answer is the second option
