In order to receive full credit, you must not only determine the correct answer, you must clearly present correct relevant work leading to that correct answer and include relevant units when appro- priate. A correct answer with insufficient or incorrect work may receive little or no credit. . The point of the worksheets are to require you to practice your communication skills in mathematics. Providing only an answer, regardless of its accuracy, is not exercising those communication skills and is of little value for the worksheet exercise.5. The number of bacteria in a culture is increasing according to the law of exponential growth. The initial population is 250 bacteria, and the population after 12 hours is double the population after 1 hour. Use this information to answer the following questions. Make sure to dene all variables and identify units. (a) Find an exponential growth model for the number of bacteria at time t. {13) Use the model from part (a) to predict the number of bactieria. after 6 hours. Round your answer to one decimal place. {:3} 'When will the population exceed 950 bacteria? Round your answer to one decimal place
