A small country in Europe has been experiencing population growth that can be modeled by the equation
\[ y = 120,000(1.042)^x \]
where \( y \) is the population of the country and \( x \) is the number of years since 2010. What is the percent change in the population of the country each year?
Answer (2)
The percentage searched is 4.2%
If you multiply some value to 1.042 this means that you are adding 4.2 %
See in the expression of formula that appears just the cited figure: "1.042"
The percent change in the population of the country each year is 4.2%. This is derived from the growth factor in the population model, which is 1.042. This indicates an annual increase of 4.2% from the original population.
