Answer:
D. Flash the BIOS
Explanation:
The function of the BIOS is to test all computer hardware that is attached to a machine before loading the operating system. Since the bios contains firmware that enables the configuration of computer hardware. when the 2 TB hard drive is connected the technician should update the program stored on the BIOS chip in other words flash the bios for it to be able to read the new hard drive. Reinstalling the drive will not make a difference as long as the BIOS still detects the 250 GB hard drive.
Answer:
temperature
Explanation:
Temperature is one of the three factors known to have remarkable influence on the effectiveness of chemical sanitizers. These sanitizers generally perform best at temperature range of 13 – 49 degrees centigrade.
Also, contact time is one of the factors that is needed for the sanitizers to effectively kill the microorganisms. The item to be cleaned should come in contact with the chemical for the recommended period of time.
Answer:
Positive media attention can transform communities in unexpected ways.
Explanation:
According to the given excerpt, it is narrated that Kathleen wrote about a town called Abbston that was recently overwhelmed by tourists as a result of the news article by a TV travel editor who wrote about the town.
Therefore, the best concluding sentence for the paragraph would be that positive media attention can transform communities in unexpected ways.
Answer:
The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.
![rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)](https://tex.z-dn.net/?f=rank%28A%29%3Drank%5Cleft%20%28%20%5Cleft%20%5B%20A%7CB%20%5Cright%20%5D%20%5Cright%20%29%5C%3Aand%5C%3An%3Drank%28A%29)
Then satisfying this theorem the system is consistent and has one single solution.
Explanation:
1) To answer that, you should have to know The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.
![rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)](https://tex.z-dn.net/?f=rank%28A%29%3Drank%5Cleft%20%28%20%5Cleft%20%5B%20A%7CB%20%5Cright%20%5D%20%5Cright%20%29%5C%3Aand%5C%3An%3Drank%28A%29)

Then the system is consistent and has a unique solution.
<em>E.g.</em>

2) Writing it as Linear system


3) The Rank (A) is 3 found through Gauss elimination


4) The rank of (A|B) is also equal to 3, found through Gauss elimination:
So this linear system is consistent and has a unique solution.
