Final answer:
The population of bacteria in the culture after 5 hours, given an initial population of 92000 bacteria and a doubling time of 7 hours, is approximately 417,371.
Step-by-step explanation:
The given population growth formula is Pₜ = P₀· 2ᵗ/ᵈ , where Pₜ is the population after t hours, Po is the initial population, t is the time in hours, and d is the doubling time.
Using this formula, we can find the population of bacteria in the culture after 5 hours, given an initial population of 92000 bacteria and a doubling time of 7 hours:
Pₜ = 92000· 2ᵗ/ᵈ
P₅ = 92000· 2⁵/⁷
P₅ = 92000· 32/7
P₅ ≈ 417,371
Therefore, the population of bacteria in the culture after 5 hours is approximately 417,371.
