A species of fish was added to a lake. The population size P() of this species can be modeled by the following function, where t is the number of years from the
time the species was added to the lake.
P(t)=2000/1+3e^-0.34t
Find the initial population size of the species and the population size after 9 years.
Round your answers to the nearest whole number as necessary.

Ответ:
The initial population size is 500 fish
Population size after 9 years: 1910 fish
Step-by-step explanation:
Mathematical Model
We usually represent real situations as mathematical functions or rules that express the dependency of one variable quantity P with another variable quantity t.
The population size of a species of fish P(x) is modeled by the following function:
Where t is the number of years elapsed since the species was added to the lake.
The initial population size can be found by substituting t for 0:
P(0)=500
The initial population size is 500 fish
The population size after t=9 years is:
Population size after 9 years: 1910 fish
