A certain culture of the bacterium Streptococcus A initially has 5 bacteria and is observed to double every 1.5 hours. (a) Find an exponential model  n(t) = n02t/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.) t =  h

A certain drug is eliminated from the bloodstream exponentially with a half-life of 36 hours. Consider a patient that receives an initial dose of 20 mg of the drug at midnight. (i) How much of the drug is in the patient's blood at 1 pm the next day? Show your answer to 1 decimal place. (ii) If growth of the bacteria which is causing the infection is inhibited at a concentration of 11500 ug of the drug. How many hours after the initial dose should the patient receive the next dose of drug or risk the infection worsening? Give your answer to the nearest whole number.
