Answer :
Sure! Let's walk through the steps to find the population of bacteria after 13 hours.
1. Understand the formula:
- The formula we are using is: [tex]\( P_t = P_0 \cdot 2^{\frac{t}{d}} \)[/tex].
- Here, [tex]\( P_t \)[/tex] is the population after [tex]\( t \)[/tex] hours.
- [tex]\( P_0 \)[/tex] is the initial population, which is 400 bacteria.
- [tex]\( t \)[/tex] is the time in hours, which is 13.
- [tex]\( d \)[/tex] is the doubling time, which is 2 hours (the population doubles every 2 hours).
2. Plug in the values:
- [tex]\( P_0 = 400 \)[/tex]
- [tex]\( t = 13 \)[/tex]
- [tex]\( d = 2 \)[/tex]
3. Calculate the exponent:
- Find [tex]\(\frac{t}{d} = \frac{13}{2}\)[/tex].
4. Compute the power of 2:
- Calculate [tex]\(2^{\frac{13}{2}}\)[/tex].
5. Calculate [tex]\( P_t \)[/tex]:
- Multiply the initial population by the result from step 4: [tex]\( P_t = 400 \times 2^{6.5} \)[/tex].
6. Round to the nearest whole number:
- After computing, round the solution to the nearest whole number to get the final population.
Following these steps, the population of bacteria in the culture after 13 hours is 36,204.
