Question

Please help me, my professor wants us to explain step by step each problem but I cant! This is worth many points so please help me! Thank you!

Writing Assignment 4 The following application and statements a., b., d., e., and f. can be found Sullivan's PreCalculus 9t www wennnnm edition pages 336-337. "A strain of E-coli SC18del-recA718 is placed into a nutrient broth at 30° Celsius and allowed to grow. The data given below are collected where x is for time in hours and y is for population. The theory states that the number of bacteria in the petri dish will initially grow according to the law of uninhibited growth. The population is measured using an optical device in which the amount of light that passes through the petri dish is measured." Time (hours), Population, y 2.5 0.175 3.5 0.38 4.5 0.63 4.75 0.76 5.255 1.20 The data above is credited to Dr. Polly Lavery, Joliet Junior College. a. Insert a scatter diagram or plot of the given data. a'. Select two points from the given data to build an exponential model. Please round your final answer to two decimal places and write your answer in the form of y ab. Note: need to show work and explain the step by step process leading to the answer. Furthermore, don't use a calculator to find the exponential model. b. Use a graphing calculator to build an exponential model from the given data. Note: include all the given data in the calculator not just two points. In addition, please explain how you input the data in the calculator and the steps to compute the exponential function/model. d. Insert a graph of the exponential model found in part b. onto the scatter diagram from part a. e. Predict the population when x 6 using the exponential model found in part b. Please show and explain your step by step solution, and please do not insert a table or a graph to answer this problem. f. Predict the time in hours when the population will reach 2.1 using the exponential model found in part b. Please show and explain your step by step solution, and please do not insert a table or a graph to answer this problem.
