In a lab, a scientist is growing bacteria for a study. The scientist begins with a bacteria population of b cells. She discovers that after 3 hours, the population of bacteria is
b2 cells. Three hours later, the bacteria population is b3 cells. If the population of the bacteria after these 6 hours is one thousand cells, what was the population at the start? Explain how you found your answer.

Going from point a to point b, the cheetah traveled at an average rate of 70 mph. returning to point a, the cheetah traveled at an average rate of 40 mph. can we say that this cheetah’s average rate was 55 mph? uchet write an equation for the average rate for the trip. remember, the cheetah runs from point a to point b and back to point a. first leg of trip: second leg of trip: ⦁ the following equation represents the average rate for the trip. is this equation equivalent to the one you wrote above? explain why or why not.
