Question: Answer b only This exercise uses the population growth model. A certain culture of the bacterium Streptococcus A initially has 7 bacteria and is observed

Answer b only

This exercise uses the population growth model. A certain culture of the bacterium Streptococcus A initially has 7 bacteria and is observed to double every 1.5 hours. (a ) Find an exponential model n(t) = no2t/a for the number of bacteria in the culture after t hours. n(t) = 7. 2 1.5 (b) Estimate the number of bacteria after 28 hours. (Round your answer to the nearest whole number. ) 728223 Ibacteria (c) After how many hours will the bacteria count reach 10,000? (Round your answer to one decimal place.) t = 15.7 Need Help?
