Acommon inhabitant of human intestines is the bacterium escherichia coli. a cell of this bacterium in a nutrient-broth medium divides into two cells every 20 minutes. the initial population of a culture is 66 cells.(a) find the relative growth rate. (assume t is measured in hours.) k = (b) find an expression for the number of cells after t hours. p(t) = (c) find the number of cells after 8 hours. cells (d) find the rate of growth after 8 hours. (round your answer to three decimal places.) billion cells per hour (e) when will the population reach 20,000 cells? (round your answer to two decimal places.) hr

Multiple-choice questions have a special grading rule determined by your instructor. assume that your instructor has decided to grade these questions in the following way: if you submit an incorrect answer to a multiple-choice question with n options, you will lose 1/(nâ’1) of the credit for that question. just like the similar multiple-choice penalty on most standardized tests, this rule is necessary to prevent random guessing.if a multiple-choice question has five answer choices and you submit one wrong answer before getting the question correct, how much credit will you lose for that part of the question? multiple-choice questions have a special grading rule determined by your instructor. assume that your instructor has decided to grade these questions in the following way: if you submit an incorrect answer to a multiple-choice question with options, you will lose of the credit for that question. just like the similar multiple-choice penalty on most standardized tests, this rule is necessary to prevent random guessing.if a multiple-choice question has five answer choices and you submit one wrong answer before getting the question correct, how much credit will you lose for that part of the question? 100% 50% 33% 25% 20%
