Modeling Exponential Growth and Decay A research student is working with a culture of bacteria that doubles in size every 26 minutes. The initial population count was 1425 bacteria. a. Rounding to four decimal places, write an exponential equation representing this situation. B(t) = (Let t be time measured in minutes.) b. Rounding to the nearest whole number, use B(t) to determine the population size after 5 hours. The population is about bacteria after 5 hours. (Recall that t is...

This exercise uses the population growth model. The count in a culture of bacteria was 400 after 2 hours and 25,600 after 6 hours. (a) What is the relative rate of growth of the bacteria population? Express your answer as a percentage. (Round your answer to the nearest whole number.) 104 % (b) What was the initial size of the culture? (Round your answer to the nearest whole number.) 200 x bacteria (c) Find a function that models the number...
