Answer:
Step-by-step explanation:
In this problem we have a exponential function of the form
where
x is the time in hours
y is the numbers of bacteria
a is the initial value
b is the base
r is the rate of growth
b=(1+r)
we have that
For x=8, y=3,300
substitute in the exponential function
solve for b
Find the value of r
The equation is equal to
For x=12 hours
substitute the value of x in the equation
