- A dirty bowl on your counter starts to grow bacteria that doubles every 10 minutes. Assuming youstarted with one single bacteria cell, how much bacteria would be present on your bowl at the end of180 minutes?A ball is dropped from a height of 128 feet. After each bounce it will rebound to a height that is 3/4 of the previous height. Theoretically, what is the total distance the ball will travel when it has stopped bouncing?Please work in summation notation
- express using sum notationDefine the concept of bounded summation. How does it differ from regular summation?Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said estimates vary between 2 and 3 for the average number of people who could be infected by a person carrying the virus. a. Assuming the worst-case scenario, 3 people are infected by one person, using proper notation create a sequence or series that represents the number of people infected by 1 person carrying the virus over a finite number of days. b. Explain why you chose what you did and what each variable represents. c. If each new “infection” occurred on successive days, how many people would be infected by the 10th day? You may use a calculator for calculations only. Show all of your work. d. Given the above scenario, how long could it potentially take to infect 80% of the population of New York City, which is 8,400,000.
