Under ideal conditions, a population of E. coli bacteria can double every 20 minutes. This behavior can be modeled by the exponential function N(t) = No (20.05t) where t is the time in minutes and No is the initial number of E. coli bacteria. Answer the following questions. a) If the initial number of E. coli bacteria is 2, how many bacteria will be present in 3 hours? 3 (Round to the nearest whole number as needed.) 2
