๐ฌ Population Growth - Secondary Level
Applying algebra to understand population dynamics
๐ Understanding Exponential Growth
Key Concept: Population grows exponentially when there are no limits.
Exponential Growth Formula
P(t) = Pโ ร e^(kt)
P(t) = Population at time t
Pโ = Initial population
k = Growth rate
t = Time

Population: 16,912,800
Year: 2022
๐ Graphing Growth
Plotting population over time helps visualize growth patterns.
๐๏ธ Provincial Comparison
Calculate growth rates for different provinces.
2010 Population: 2,191,225
2022 Population: 3,078,542
Growth Rate: 3.4%
2030 Projection: 4,032,456
๐ Practice Problems
Problem 1
A city has 500,000 people and grows at 3% per year. What will be the population after 10 years?
Problem 2
Zambia's population doubled from 2.32M (1950) to 4.64M. How many years did it take?
Problem 3
If a population grows from 1M to 2M in 20 years, what is the growth rate?
