Answer:
:
Function f(t) is given as:
\boxed{ \bf{f(t) = 500.e^{0.05\:t}}}
f(t)=500.e
0.05t
here, 't' is the time and is measured in minutes.
We are required to find the population of bacteria after 4 hours.
Hence in 4 hours, we have 4 × 60 = 240 minutes. Hence the value of 't' is 240 minutes.
Substituting the values we get:
\begin{gathered}f(240) = 500.e^{(0.05 \times 240)}\\\\f(240) = 500 \times e^{(12)}\\\\f(240) = 500 \times 1.62 \times 10^5\\\\\boxed{ \bf{f(240) = 8.13 \times 10^7}}\end{gathered}
f(240)=500.e
(0.05×240)
f(240)=500×e
(12)
f(240)=500×1.62×10
5
f(240)=8.13×10
7
Hence the amount of bacteria present after 4 hours is 8.13 × 10⁷ (approx).
