bacteria culture starts with 400 bacteria and grows at a rate proportional to its size. After 4 hours, there are 9000 bacteria.
yawa3891 [41]

Answer:

A) P = P_0 e^{rt}

B) 19564

C) 5.5 or 6 hours

Explanation:

A) The formula that can be used for bacteria after "t" hours is

P = P_0 e^{rt}

Where ,

P represents the population after "t" hours

P_0 represents the initial population.

r represents the rate of growth of population

t represents the time taken by the population to grow

B) Here let us first find the rate of population growth.

9000 = 400 * e^{r*4}\\3.11 = r* 4\\r = 0.778

Thus, the population of bacteria after 5 hours

P = 400 * e^{0.778 * 5} \\P = 400* 48.91\\P =  19564\\

C)

30000 = 400 * e^{0.778 * t) \\\\4.317 = 0.778 * t\\t = 5.549\\or t= 5.5 or 6

How could you use what you learned to change salt water into a source of drinking water?
KengaRu [80]
You can try this simple experiment to change salt water into freshwater. This is a process called "desalination." The water evaporates and leaves the salt behind, so the water you collect in your collection glass is clean drinking water. ... Add a few spoonfuls of salt to the water. Make the water as salty as you like.
