Final answer:
The growth in the number of Internet users in a certain country between 1990 and 2019 can be approximated by a logistic function with a growth rate of 0.0017.
Step-by-step explanation:
The growth in the number of Internet users in a certain country between 1990 and 2019 can be approximated by a logistic function with a growth rate of 0.0017. A logistic function is a mathematical function that models growth that starts off slow, then accelerates and eventually levels off.
For example, let's say that in 1990, there were 10 million Internet users in the country. Using the logistic function, we can calculate the number of Internet users in any given year. To find the number of Internet users in 2019, we can substitute t = 29 into the logistic function:
N(t) = K / (1 + e^(-kt))
N(29) = K / (1 + e^(-0.0017 * 29))
Where N(t) is the number of Internet users at time t and K is the maximum number of Internet users that the country can support. By solving this equation, we can find the growth in the number of Internet users between 1990 and 2019.
