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

ANSWER :

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 :

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