Algebra investigation (GD3: Application of Skill, GD7: Quality) Part A For one strain of bacteria, each bacterium divides into two every minute. The table shows the number of bacteria present in a particular sample for the first 5 minutes. Time (minutes) number of bacteria present 3 12 AWN- 24 48 96 Write down an algebraic rule linking the number of bacteria present at a particular time to the number present one minute previously. ") Write down an expression for the number of bacteria present after t minutes ") Calculate the number of bacteria present after 2 hours. (State any assumptions you make.) iv) Calculate the time for the colony to reach 1 million bacteria
