Solve this question of matrices in Attachment ​

Answer»

\large\underline{\sf{Given- }}

\rm :\longmapsto\:2A + 2B = \begin{gathered}\sf \left[\begin{array}{ccc}2& - 1&4\\3&2&5\end{array}\right]\end{gathered}

and

\rm :\longmapsto\:A + 2B = \begin{gathered}\sf \left[\begin{array}{ccc}5& 0&3\\1&6&2\end{array}\right]\end{gathered}

\large\underline{\sf{To\:Find - }}

\boxed{ \bf{ \: 2B}}

\large\underline{\sf{Solution-}}

Given that,

\rm :\longmapsto\:2A + 2B = \begin{gathered}\sf \left[\begin{array}{ccc}2& - 1&4\\3&2&5\end{array}\right]\end{gathered} -  -  - (1)

and

\rm :\longmapsto\:A + 2B = \begin{gathered}\sf \left[\begin{array}{ccc}5& 0&3\\1&6&2\end{array}\right]\end{gathered} -  -  - (2)

Now, multiply EQUATION (2) by 2, we get

\rm :\longmapsto\:2A + 4B =2 \begin{gathered}\sf \left[\begin{array}{ccc}5& 0&3\\1&6&2\end{array}\right]\end{gathered}

\rm :\longmapsto\:2A + 4B = \begin{gathered}\sf \left[\begin{array}{ccc}10& 0&6\\2&12&4\end{array}\right]\end{gathered}  -  -  - (3)

Now, Subtracting equation (2) from equation (3), we get

\rm :\longmapsto\:2B = \begin{gathered}\sf \left[\begin{array}{ccc}10& 0&6\\2&12&4\end{array}\right]\end{gathered} - \begin{gathered}\sf \left[\begin{array}{ccc}2& - 1&4\\3&2&5\end{array}\right]\end{gathered}

\rm :\longmapsto\:2B = \begin{gathered}\sf \left[\begin{array}{ccc}10 - 2& 0  + 1&6 - 4\\2 - 3&12 - 2&4 - 5\end{array}\right]\end{gathered}

\rm :\longmapsto\:2B = \begin{gathered}\sf \left[\begin{array}{ccc}8&1&2\\ - 1&10& - 1\end{array}\right]\end{gathered}

Hence,

Additional Information :-

1. Matrix addition is POSSIBLE only when order of matrix are same otherwise its meaningless.

2. Matrix subtraction is possible only when order of matrix are same otherwise its meaningless.

3. Matrix multiplication is defined when number of COLUMNS of pre multiplier is equal to the number of rows of post multiplier.

Builder ‘A’ says that the flat is square shaped and the area is 3853 square feetb) Builder ‘B’ says that the flat is square shaped and the area is 3249 square feet .c) Builder ‘C says that the flat is square shaped and the area is 3844 square feet.A) Without doing calculations, Identify which builder is definitely giving a wrong flat size . Explain, how you derive this conclusion.

Answer»

ANSWER:

Builder A is wrong

Step-by-step explanation:

All of them SAY that the flat is square-shaped. So the area should be the square of sides

Area=SIDE²

So let's see if the area is actually a square of a side

Builder A: Area=3853 square feet

Now, we see the digit at Ones place. By observing, we see that there is no number whose Ones digit when squared, gives 3 at place(Think of square of numbers from 1 to 10 and the Ones digit at the squared number)

Builder B and C: Area=3249 and 3844 square feet respectively

In both of there cases, we can see that there are numbers with there Ones digit squaring to 4 (B's case) and 9 (C's case) as 2 and 4.

THEREFORE, A is wrong

M-3mn+n+9 from 11m-7mn+2n-5

Answer»

ANSWER:

10m - 4MN + n - 14

Step-by-step explanation:

11m - 7MN + 2n - 5  minus m - 3mn + n + 9  

11m - 7mn + 2n - 5  + (-)m - 3mn + n + 9  

*Multiplying the second equation by a NEGATIVE so we can add instead of subtract* (Negative times a negative is a positive; a postive times a negative is a negative)

11m - 7mn + 2n - 5  + -m + 3mn - n - 9

10m - 4mn + n - 14

Step-by-step explanation:

Caste-based trade AMONG the Nakarattars of Tamil Nadu This is not to say that the Nakarattar banking system resembled an economist’s model of Western-style banking systems … the Nakarattars loaned and deposited money with one another in caste-defined social relationships based on business territory, residential location, descent, marriage, and common cult membership. Unlike in modern Western banking systems, it was the reputation, decisions, and reserve deposits shared among exchange spheres defined according to these principles, and not a government-controlled central bank, that … assured public confidence in individual Nakarattars as representatives of the caste as a whole. In other words, the Nakarattar banking system was a caste-based banking system. Individual Nakarattars organised their LIVES around participation in and management of various communal institutions adapted to the task of accumulating and distributing reserves of capital. Source: Rudner

Read the extracts from Caste and Capitalism in Colonial INDIA(Rudner 1994) in the box and ANSWER the following questions.

1.What are the significant differences between the Nakarattar bankingsystem and the modern Western banking system, according to the author?

2.What are the different WAYS in which Nakarattar trading andbanking activities are linked to other social structures?

3.Can you think of examples within the modern capitalist economy whereeconomic activities are similarly ‘embedded’ in social structures?
