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:
Explanation:
1. The answer is No, interface cannot have constructors. ... In order to call any method we need an object since there is no need to have object of interface, there is no need of having constructor in interface (Constructor is being called during creation of object).
2.A final class is considered complete and can not be subclassed (It's methods can not be overridden ). In case of abstract class, we have to proved implementation to abstract methods in subclasses. A final class can not have abstract methods and an abstract class can not be declared final.
3.private constructors are acceptable, however the class should be marked final instead, as doing so means the class is to be extended.
4.Yes! Abstract classes can have constructors! Yes, when we define a class to be an Abstract Class it cannot be instantiated(i.e an object cannot be created) but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.
I'm not sure on what you mean by this however lets say that it may contain a device, when entering DO NOT TOUCH ANYTHING, there are different methods on how a device could be triggered either from light switches or by trip wire which its best to leave the facility over all however lets say you cannot then stop listen for any ticking if not then have a flash light, if the room lights are turned off leave them off use a flash light but be careful where you shine it there could be light sensors on the device that trigger when a light hits it hence why the lights are off. when having a flash light you could be able to see a glare of a wire which could be a trip wire. there are many possibilities in how the device was made from timers, trip wire, sound,light,pressure, switches, electronic waves from phones may effect the device and could activate it as well. But anyways this is all a factor and its best to be careful and if able evacuate if the device is in a weird location at a odd time you know its not suppose to be there, and or items moved that are never moved and if it is never moved then there is dust that could have a odd shape like a hand print. Anyways im not sure if your looking for this type of answer but its good to know!
