The bacteria Streptococcus pneumoniae (S. pneumoniae) is the cause of many human diseases, the most common being pneumonia. A culture of these bacteria initially has 10 bacteria and increases at a rate of 25% per hour. (a) Find the hourly growth factor a. a = Find an exponential model f(t) = Cat for the bacteria count in the sample, where t is measured in hours. f(t) = (b) Use the model you found to predict the number of bacteria in the sample after 4 hours.
