Healthcare associated or nosocomial pneumonia are acquired by non-hospitalized patients in hospitals or other health care facilities. Pneumonia are poly-microbial in origin and the causative agents are viruses, bacteria and fungi. In nosocomial pneumonia, bacteria enter the lower respiratory tract due to mechanical ventilation. Meanwhile, persons in general population experience community-acquired pneumonia.

In an experiment, a certain colony of bacteria initially has a population of 50,000. A reading is taken every 2 hours, and at th
Iteru [2.4K]

Answer:

1) Recursive definition: p_n = (50,000)3^n

2) At the beginning of the 4th interval

Explanation:

1)

The initial population of the bacteria at time zero is

p_0 = 50,000

Here we are told that the reading is taken every two hours; we call this time interval "n", so

n=2 h

And also, after every time interval n, the number of bacteria has tripled.

This means that when n = 1,

p_1 = 3 p_0

And when n=2,

p_2 = 3 p_1 = 3(3p_0)=9 p_0

Applied recursively, we get

p_n = 3^n p_0

And substituting p0,

p_n = (50,000)3^n (1)

2)

Here we want to find at the beginning of which interval there are

p=1,350,000

bacteria.

This means that we can rewrite eq.(1) as

1,350,000=(50,000)3^n

By simplifying,

27=3^n

Which means that

n=3

However, this means that the number of bacteria is 1,350,000 after 3 time intervals; therefore, at the beginning of the 4th interval.
