A culture of bacteria doubles every hour. If there are 500 bacteria at the beginning, how many bacteria will there be after 9 hours?
Assumptions and givens;
B(h) = B(0) * 2^h
We want h = 9, so we have:
B(9) = 500 * 2^9
B(9) = 500 * 512
B(9) = 256,000
Assumptions and givens;
- h is the number of hours.
- B(h) is the number of bacteria at time h
- B(0) is the starting bacteria amount
- Doubling means multiplying by 2, so we have:
B(h) = B(0) * 2^h
We want h = 9, so we have:
B(9) = 500 * 2^9
B(9) = 500 * 512
B(9) = 256,000
