Answer:
The expression for the number of bacteria after t hours is
Step-by-step explanation:
When introduced into a nutrient broth, the culture grows at a rate proportional to its size.
This means that the size of the population, after t hours, is modeled by the following differential equation:
In which R is the growth rate.
The solution of this differential equation is:
In which P(0) is the initial population.
A culture of the bacterium Salmonella enteritidis initially contains 50 cells.
This means that , and so:
After 1.5 hours, the population has increased to 775.
This means that . We use this to find r. So
The expression is:
The expression for the number of bacteria after t hours is
Answer: we should have that:
Step-by-step explanation:
We know that f(x) is an odd function, this means that f(-x) = -f(x)
We know that:
this means that wen we aproximate to zero for the right (the positive side) we have that the value is.
First, this tell us that f(x) can not be a continue function, because of the fact that is odd we will have that when we aproximate the same lim but from the negative side, we will have that:
