(a)
\The logistic growth model of bacterium after
hours is
eagles.
Substitute
in logistic growth model to find the carrying capacity of the environment.

Therefore.the carrying capacity of the environment is
eagles.
(b)
\The standard logistic growth model of population after
years is
.
The logistic growth model of eagle after
years is
eagles.
Compare the logistic model with standard logistic model
,
and
.
The growth rate is for standard logistic model is
.
Therefore, the growth rate of the eagle is
per year.
The growth rate of the eagle is
per year.
(c)
\Find the population after
years.
The equation is
.
Substitute 
.

Therefore,the size of population after
years is
eagles.
(d)
\Find the time when the size of population is
eagles.
The equation is
.


Therefore, the population reaches
eagles after
years.
(e)
\The function is
.
The carrying capacity of the environment is
grams.
One-half the carrying capacity is
grams.
The time when population size reaches
grams .
Substituting
.


Therefore, the population size of bacteria reaches one-half the carrying capacity after
years.
(a) The carrying capacity of the environment is
eagles.
(b) The growth rate of the eagle is
per year.
(c) The size of population after
years is
eagles.
(d) The populationreaches
eagles after
years.
(e) The population size of bacteria reaches one-half the carrying capacity after
years.
