This exercise uses the population growth model. A certain culture of the bacterium Streptococcus A initially has 9 bacteria and is observed to double every 1.5 hours. (a) Find an exponential model n(t) no2/a for the number of bacteria in the culture after t hours. - n(t)- (b) Estimate the number of bacteria after 35 hours. (Round your answer to the nearest whole number). bacteria (c) After how many hours will the bacteria count reach 10,000? (Round your answer to one decimal place.)
