Question

A colony of bacteria is growing exponentially according to thefunction below, where t is in hours. What will the approximatenumber of bacteria be after 8 hours?

Answer 1

A. 2407

EXPLANATION :

From the problem, we have the given formula :

`B(t)=4\cdot e^(0.8t)`

where B(t) is the number of bacteria after t hours.

e = Euler's number

After t = 8 hours, the number of bacteria is :

`\begin{gathered} B(t)=4\cdot e^(0.8(8)) \\ \\ B(t)=2407.38\sim2407 \end{gathered}`
