Answer 1

Answer:

A

Step-by-step explanation:

Answer 2

Solving this problem requires the supplement of the actual expression. However I believe you forgot to include it with the question.

However I believe that the expression is in the form of:

y = A e^(-k t)

where,

y is the number of bacteria after time t

A is a constant and represents the initial number of bacteria

k is the growth rate in decimal form

t is time

 

So whatever is located in A is the initial number of bacteria, while k times 100% is the growth rate.
