A culture contains 25,000 bacteria, with the population increasing exponentially. The culture contains 35,000 bacteria after 6 hours. a. Write a function in the form y = yo e" giving the number of bacteria after t hours. b. Write the function from part a in the form y = yoa'. c. How long will it be until there are 65,000 bacteria? a. The exponential equation is (Round to three decimal places as needed.) b. The function from part a in the form y = ya' is (Round to three decimal places as needed.) c. There will be 65,000 bacteria in about hours. (Round to one decimal place as needed.)
