Correct answer would be <span>A) <u>quartz</u></span>. Plastic, nylon, and rubber can all be broken down or heated to make it expand, and be used in common products.
Hope this helped :)
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.
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.
Answer:
The correct option for accessing the value in sarray[3] is : d) *(sptr+3)
Explanation:
a) *sptr[*3] is wrong option because its syntax is not right it will give errors.
b) *sptr+3 is also wrong option because it will add 3 to the value of sarray[0].
c) sptr+3 is wrong option because it will only access the address of sarray[3] not the value it contains.
d) *(sptr +3) is correct syntax for accessing value in sarray[3] by using pointer
Answer:
Physical layer
Explanation:
OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;
1. Physical Layer
2. Data link Layer
3. Network Layer
4. Transport Layer
5. Session Layer
6. Presentation Layer
7. Application Layer
Each layer has its unique functionality which is responsible for the proper functioning of the communication services.
In the OSI model, the physical layer is the first and lowest layer. Just like its name physical, it addresses and provides information about the physical characteristics such as type of connector, cable type, length of cable, etc., of a network.
This ultimately implies that, the physical layer of the network (OSI) model layer provides information about the physical dimensions of a network connector such as a RJ45. A RJ45 is used for connecting a CAT-5 or CAT-6 cable to a networking device.
Risk assessment should cover all the processes and systems included in an organization. This means this includes also the technical support including <span>firewalls, secure operating systems and networks, and antivirus protection. Risk is always present and inevitable in every way so it is important to anticipate and make early detections to counter with actions as soon as one can.</span>
