There are 70,000 bacteria present in a culture. An antibiotic is introduced to the culture and the number of bacteria is reduced by half every 4 hours. Which of the following statements are true? Select all that apply.
two hours after the antibiotic is introduced, there are 35,000 bacteria present in the culture.
24 hours after the antibiotic is introduced, the number of bacteria in the culture is reduced to 1093.
The amount of bacteria present in the culture during the 24 hours after the antibiotic is introduced is an example of exponential decay.
The half-life of the bacteria after the antibiotic is introduced is 2 hours.
The function B (x) = 70,000(0.5)*, where x is the number of 4 hour periods, represents the
amount of bacteria present after the antibiotic is introduced.
- Two hours after the antibiotic is introduced, there are 35,000 bacteria present in the culture.
- The amount of bacteria present in the culture during the 24 hours after the antibiotic is introduced is an example of exponential decay.
- The function B(x) = 70,000(0.5)^x, where x is the number of 4 hour periods, represents the amount of bacteria present after the antibiotic is introduced.
