Chapter 4.4, Problem 198E
The following questions consider the Gompertz equation, a modification for logistic growth, which is often used for modeling cancer growth, specifically the number of tumor cells.
198. [T] It is estimated that the world human population reached 3 billion people in 1959 and 6 billion in 1999.
Assuming a carrying capacity of 16 billion humans, write and solve the differential equation for logistic growth. and determine what year the population reached 7 billion.
