Answer:
a)
b) 334,858 bacteria
c) 4.67 hours
d) 2 hours
Step-by-step explanation:
a) Initial number of bacteria is the coefficient, that is, 250. And the growth rate is the coefficient besides “t”: 0.15. It’s rate of growth because of its positive sign; when it’s negative, it’s taken as rate of decay.
Another way to see that is the following:
Initial number of bacteria is N(0), which implies
. And
. The process is:
b) After 2 days means
. So, we just replace and operate:
c)
d)
The limit of the expression as x approaches -3 is -24
<h3>How to determine the limit of the expression?</h3>
The expression is given as:

As x approaches -3.
The limit expression becomes

Substitute -3 for x in the expression

Evaluate the expression

Hence, the limit of the expression as x approaches -3 is -24
