    Sometimes, you may be given a doubling or tripling rate rather than a growth rate in percent. For example, if you are told that the number of cells in a bacterial culture doubles every hour, then the equation to model the situation would be: y = C β‹… 2 t with t in hours.

    similar). The starting amount of bacteria is 1000, so 𝐴=1000. To find 𝑏, plug in 3 for 𝑑 and 2000 for 𝑦 (since the population doubles in 3 hours): 2000=1000𝑏3, divide both sides by 1000 to get 2=𝑏3. ⁄Raise both sides to the 13 power to get 21⁄3=(𝑏3)1⁄3, so 𝑏=21⁄3. Thus, the function is 𝑦=1000(21⁄3) 𝑑, orFile Size: 201KB

    2 hours comprise of 4 doubling periods. Therefore, after 2 hours, the bacteria population is N = = = 24000. ANSWER Problem 2 A bacteria culture initially contains 1500 bacteria and doubles every half an hour. Find the size of the bacterial population after 100 minutes. Solution I will solve this problem using a double period model, again. The formula for the currecnt population is N = 1500*2^(t/0.5) = …

    Answer: Since t hours is the same as 2t half-hours, the culture will have doubled 2t times. Therefore, there will be 500·22t bacteria. (c) How many bacteria are there after 40 minutes? Answer: There are two possible answers depending on how you interpret the set-up to the problem. If each bacterium in the culture doubles once every half-hour on the half-hour, then each one will double after exactly 30 …
