a) Determine the growth rate of the bacteria population at each of the following times.

i>3h

ii>8h

Ans: find the 1st derivative which is 20-2t, substitute the times given and it yield a negative number and that in thousands is the answer.

b)What are the implications of the growth rates in part a)

Ans: since the answer are negative they suggest that the population of the bacteria is decreasing.

c)When does the bacteria population stop growing? What is the population at this time.

Ans: set the original equation to zero it will give a time in hours and substitute that time into the first derivative.
