A petri dish originally contains 200 bacteria. Their population grows exponentially. The number of bacteria is given by F(t) = 200(1.20)^t, where t is time in hours. You need to find out when the number of bacteria is more than triple the original number. Which inequality should you use?
Question:
A petri dish originally contains 200 bacteria. Their population grows exponentially. The number of bacteria is given by F(t) = 200(1.20)^t, where t is time in hours. You need to find out when the number of bacteria is more than triple the original number. Which inequality should you use?
Choices:
- 600 > 200(1.20)^t
- 200(1.20)^t > 600
- 200(1.20)^t > 600
- 600(1.20)^t > 200
Answer:
200(1.20)^t > 600
