slega [8]

A Python library is a collection of modules and packages.

A Python library contains bundles of code that can be used repeatedly in different programs. Through this Python Programming becomes simpler and convenient for the programmer. As we don't need to write the same code again and again for different programs.

As Python is developed under an OSI-approved open source license which makes it freely usable and distributable, even for commercial use.

Python is an open source programming language that was made to be easy to read and powerful. In Python, a program called an interpreter runs Python code on almost any kind of computer.

Hence, the answer was given and explained above.

Show that the set of vectors {(−4,1,3),(5,1,6),(6,0,2)} does not span R 3 , but that it does span the subspace of R 3 consisting

Alika [10]

Answer:

The vectors does not span R3 and only span a subspace of R3 which satisfies x+13y-3z=0

Explanation:

The vectors are given as

$v_1=\left[\begin{array}{c}-4&1&3\end{array}\right] \\v_2=\left[\begin{array}{c}-5&1&6\end{array}\right] \\v_3=\left[\begin{array}{c}6&0&2\end{array}\right]$

Now if the vectors would span the $R^3$ , the rank of the consolidated matrix will be 3 if it is not 3 this indicates that the vectors does not span the $R^3$ .

So the matrix is given as

$M=\left[\begin{array}{ccc}v_1&v_2&v_3\end{array}\right] \\M=\left[\begin{array}{ccc}-4&5&6\\1&1&0\\3&6&2\end{array}\right]\\$

In order to calculate the rank, the matrix is reduced to the Row Echelon form as

$\approx \left[\begin{array}{ccc}-4&5&6\\ 0&\frac{9}{4}&\frac{3}{2}\\ 3&6&2\end{array}\right] R_2 \rightarrow R_2+\frac{R_1}{4}$

$\approx \left[\begin{array}{ccc}-4&5&6\\ 0&\frac{9}{4}&\frac{3}{2}\\ 0&\frac{39}{4}&\frac{13}{2}\end{array}\right] R_3 \rightarrow R_3+\frac{3R_1}{4}\\$

$\approx \left[\begin{array}{ccc}-4&5&6\\ 0&\frac{39}{4}&\frac{13}{2\\ 0&\frac{9}{4}&\frac{3}{2}}\end{array}\right] R_2\:\leftrightarrow \:R_3$

$\approx \left[\begin{array}{ccc}-4&5&6\\ 0&\frac{39}{4}&\frac{13}{2}\\ 0&0&0\end{array}\right] R_3 \rightarrow R_3-\frac{3R_2}{13}\\$

As the Rank is given as number of non-zero rows in the Row echelon form which are 2 so the rank is 2.

Thus this indicates that the vectors does not span $R^3$

<em>Now for any vector the corresponding equation is formulated by using the combined matrix which is given as for any arbitrary vector and the coordinate as </em>

<em /> $v=\left[\begin{array}{c}x&y&z\end{array}\right]$ <em />

<em /> $c=\left[\begin{array}{c}c_1&c_2&c_3\end{array}\right]$ <em />

<em /> $Mc=v$ <em />

<em /> $\left[\begin{array}{ccc}-4&5&6\\1&1&0\\3&6&2\end{array}\right]\left[\begin{array}{c}c_1&c_2&c_3\end{array}\right]=\left[\begin{array}{c}x&y&z\end{array}\right]$ <em />

<em /> $M=\left[\begin{array}{ccccc}v_1&v_2&v_3& | &v\end{array}\right] \\M=\left[\begin{array}{ccccc}-4&5&6&|&x\\1&1&0&|&y\\3&6&2&|&z\end{array}\right]\\$ <em />

Now converting the combined matrix as

$\approx \left[\begin{array}{ccccc}-4&5&6&|&x\\ 0&\frac{9}{4}&\frac{3}{2}&|&\frac{4y+x}{4}\\ 3&6&2&|&z\end{array}\right] R_2 \rightarrow R_2+\frac{R_1}{4}\\$

$\approx \left[\begin{array}{ccccc}-4&5&6&|&x\\ 0&\frac{9}{4}&\frac{3}{2}&|&\frac{4y+x}{4}\\ 0&\frac{39}{4}&\frac{13}{2}&|&\frac{4z+3x}{4}\end{array}\right] R_3 \rightarrow R_3+\frac{3R_1}{4}\\$

$\approx \left[\begin{array}{ccccc}-4&5&6&|&x\\ 0&\frac{39}{4}&\frac{13}{2}&|&\frac{4z+3x}{4}\\ 0&\frac{9}{4}&\frac{3}{2}&|&\frac{4y+x}{4}\end{array}\right] R_3 \leftrightarrow R_2\\$

$\approx \left[\begin{array}{ccccc}-4&5&6&|&x\\ 0&\frac{39}{4}&\frac{13}{2}&|&\frac{4z+3x}{4}\\ 0&0&0&|&\frac{13y+x-3z}{13}\end{array}\right] R_3 \rightarrow R_3-\frac{3R_2}{13}\\$

From this it is seen that whatever the values of the coordinates does not effect the value of the plane with equation as

$\frac{13y+x-3z}{13}=0\\or\\13y+x-3z=0\\$

So it is verified that the subspace of R3 such that it satisfies x+13y-3z=0 consists of all vectors.

Target profit a.are when sales and costs are exactly equal. b.can be calculated by modifying the break-even equation. c.equals d

Irina-Kira [14]

Answer:

b. can be calculated by modifying the break-even equation.

Explanation:

As the name implies, target profit can be explained to be the certain amount a business enterprise or a business organisation targets to hit at the end of its sales or at the end of her business dealings.

It can be easily seen in a cash flow planning as it is once modified to approximate cash flow, and also used for revealing expected results to investors and lenders. In all that it is been used for, in the scenario above, it also can be calculated by modifying the break-even equation, and deriving more conservative budgeting packages in business development too.

Adjust the contribution margin per unit and units sold based on an expected sales promotion.

Alter the fixed cost total and the contribution margin per unit for the effects of outsourcing production.

Alter the contribution margin for the effects of changing to a just-in-time production system.

If there is continually a large unfavorable variance between the target and actual profit, it may be necessary to examine the system used to derive the target profit,

Orlov [11]

Answer:

overcome the challenge of deciding about further enlargement

Explanation:

The World Trade Organization main goal is to eliminate both tariff and non-tarrif barriers in world trade. It has 164 members states, and has been largely successful in this goal.

These achievements, as well as the achievements of other multilateral trade agreements help the European Union overcome debates about further enlargement and integration because not only do they lay the foundation for future economic integration, but also they represent empirical evidence that proves that economic integration is largely benefitial to signing countries.
