A culture of bacteria in a petri dish is doubling every hour. If there are 100 bacteria at time t=0, how many bacteria will there be in 12 hours?

409600

a culture started with 2000 bacteria. after 2 hour , it grew to 2,400 bacteria. predict how many bacteria will be present after 10 hours. round your answer to the nearest whole number.

4,000

Putting this information into the exponential growth formula gets you the equation y=100(2^x) where x equals the number of hours. Plugging in 12 for x, you get 409600.

. A lab is growing bacteria in a culture dish. The amount of bacteria in the dish doubles every 4 hours. Initially, there are 900 bacteria in the dish. How many are in the dish after 12 hours?
