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

____ [38]

Answer:

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:

$\displaystyle P(t)=\frac{3000}{1+3e^{-0.34t}}$

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:

$\displaystyle P(0)=\frac{2000}{1+3e^{-0.34*0}}$

$\displaystyle P(0)=\frac{2000}{1+3*1}$

$\displaystyle P(0)=\frac{2000}{4}$

P(0)=500

The initial population size is 500 fish

The population size after t=9 years is:

$\displaystyle P(9)=\frac{2000}{1+3e^{-0.34*9}}$

$\displaystyle P(9)=\frac{2000}{1+3e^{-3.06}}$

$\displaystyle P(9)=\frac{2000}{1.047}$

$P(9)\approx 1910$

Population size after 9 years: 1910 fish
