Answer:
1.4% is the maximum acceptable annual rate of growth such that the population must stay below 24 billion during the next 100 years.
Step-by-step explanation:
We are given the following in the question:
The exponential growth model is given by:

where k is the growth rate, t is time in years and
is constant.
The world population is 5.9 billion in 2006.
Thus, t = 0 for 2006

We have to find the maximum acceptable annual rate of growth such that the population must stay below 24 billion during the next 100 years.
Putting these values in the growth model, we have,

1.4% is the maximum acceptable annual rate of growth such that the population must stay below 24 billion during the next 100 years.
The answer is 45 because supplement means the sum of 180 so 180 divided by 4 is 45 and t=45
27
Step by step explanation This is how I got the answer to your question and I gave you the solution I hope this helps you out
4×11+1=45
A+B+C=180 60+75+C=180 180_130=c c=45
