What would you have to know about the pivot columns in an augmented matrix in order to know that the linear system is consistent
Scrat [10]

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)

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)

rank(A)

Then the system is consistent and has a unique solution.

<em>E.g.</em>

\left\{\begin{matrix}x-3y-2z=6 \\ 2x-4y-3z=8 \\ -3x+6y+8z=-5  \end{matrix}\right.

2) Writing it as Linear system

A=\begin{pmatrix}1 & -3 &-2 \\  2& -4 &-3 \\ -3 &6  &8 \end{pmatrix} B=\begin{pmatrix}6\\ 8\\ 5\end{pmatrix}

rank(A) =\left(\begin{matrix}7 & 0 & 0 \\0 & 7 & 0 \\0 & 0 & 7\end{matrix}\right)=3

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

(A|B)=\begin{pmatrix}1 & -3 &-2  &6 \\  2& -4 &-3  &8 \\  -3&6  &8  &-5 \end{pmatrix}

rank(A|B)=\left(\begin{matrix}1 & -3 & -2 \\0 & 2 & 1 \\0 & 0 & \frac{7}{2}\end{matrix}\right)=3

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.

A data in database can be presented in _____ format​
Serggg [28]

Answer:

Data is stored in tables, where each row is an item in a collection, and each column represents a particular attribute of the items. Well-designed relational databases conventionally follow third normal form (3NF), in which no data is duplicated in the system. ... With a homogenous data set, it is highly space efficient

The following pseudocode describes how a bookstore computes the price of an order from the total price and the number of the boo
ICE Princess25 [194]

Answer:

float bookExamplePrice = 15.25;

float bookTax = 7.5;

float bookShippingPrice = 2.0;

float Test = bookExamplePrice / 100;

float Tax = Test * bookTax;

float FullPrice = Tax + bookExamplePrice + bookShippingPrice;

// I don't know how to remove the numbers after the first two decimals.

// I tested this program. It works!

// The text after the two slashes don't run when you compile them.

printf("Price: $%.6f\n",FullPrice);
