In a lab experiment, 10 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 29 hours. How many bacteria would there be after 21 hours, to the nearest whole number?
Added by Elijah J.
Step 1
Since the bacteria doubles every 29 hours, in 21 hours, it would have doubled approximately 21/29 = 0.724 times. The number of bacteria after doubling is found by multiplying the initial number by 2 raised to the number of times it doubles. So, the number of Show more…

At the beginning of an experiment, a culture contains 200 H. pylori bacteria. An hour later there are 205 bacteria. Assuming that the $H$. pylori bacteria grow exponentially, how many will there be after 10 hours? After 2 days?
