f(x)=x^2+20x+40
Answers
f(x)=x²+20x+40
To complete the square, the same value needs to be added to both sides.
f(x)+?=x²+20x+?+40
Now i make the same thing in different forms ok
To complete the square x²+20x+100=(x+10)² add 100 to the expression

Final answer:
To rewrite the function f(x) = x² + 20x + 40 by completing the square, we find half the coefficient of the x term, square it, subtract the constant term in the original equation from this squared result, then rewrite the function as (x+10)^2 - 60.
Explanation:
When you're asked to rewrite the function by completing the square, there are certain steps to follow. We start with the function f(x) = x² + 20x + 40.
- First, take the coefficient of the x term (in our case, 20) and divide it by 2. This would yield 10.
- Next, square the result from step 1. That is 10² = 100.
- Subtract the constant term in the original equation from the squared result i.e. 100 - 40 = 60.
- Finally, the equation takes this form: f(x) = (x+10)² - 60.

Job A - Job D - Job E - Job B - Job C
Step-by-step explanation:
Job A = 2
Job B = 10
Job C = 15
Job D = 6
Job E = 8
SJN (Shortest Job Next) is also known as Shortest Job First. In Shortest Job Next, the job with the shortest time among the available jobs is executed first then followed by the next job having the shortest time till all the jobs are finally executed.
Since all the five jobs are already in the queue: they will be processed based on the job having the shortest CPU time among the available job.
Job A will be processed first since it has smallest time of 2, followed by Job D with a time of 6, followed by Job E with a time of 8, followed by Job B with a time of 10 and finally Job C which is processed last.
