A 2x3 matrix is **shaped much differently, like matrix B**. Matrix B has 2 rows and 3 columns. We call numbers or values within the matrix 'elements. ' There are six elements in both matrix A and matrix B.

The determinant is a special number that can be calculated from a matrix.**Summary**

- For a 2×2 matrix the determinant is ad - bc.
- For a 3×3 matrix multiply a by the determinant of the 2×2 matrix that is not in a's row or column, likewise for b and c, but remember that b has a negative sign!

The answer is that, if A is a square matrix of order n×n, **det(cA) = c ^{n}det(A)**. To prove this, remember that multiplying any row or column of a square matrix by a constant c will change the determinant by a factor of c.

A 2x3 matrix is **shaped much differently, like matrix B**. Matrix B has 2 rows and 3 columns. We call numbers or values within the matrix 'elements. ' There are six elements in both matrix A and matrix B.

To find determinant of 3x3 matrix, you first take the first element of the first row and multiply it by a secondary 2x2 matrix which comes from the elements remaining in the 3x3 matrix that do not belong to the row or column to which your first selected element belongs.

det(2A) = **360 = (8)(45) = 2 ^{3}det(A)** Hence the property is verified. Example 2: Let A be an n × n matrix. (a) det(A) = det(A

**det(AB) = det(A) det(B)**. Proof: If A is not invertible, then AB is not invertible, then the theorem holds, because 0 = det(AB) = det(A) det(B)=0.

The main purpose behind communicative language teaching methods is **to prepare students to be confident communicators for different real-life contexts, through repetitive oral practices and student-student cooperation**. In CLT, communication is the end and the means of the teaching method.

This means Tina started her preparation in **11 ^{th} standard** which would last for up to eight years. This was not a single year of preparation. When you start preparing for civil services you are told about NCERT books.

General subjects are suited to students who are interested in going to university. They tend to be more 'academic' than Applied subjects. Applied subjects are suited to students who are interested in vocational education and training, or work. They tend to have a more 'real world' focus.

A cladogram is **an evolutionary tree that diagrams the ancestral relationships among organisms**. In the past, cladograms were drawn based on similarities in phenotypes or physical traits among organisms.

Depending on the type of data, the data collection method is divided into two categories namely, **Primary Data Collection methods**. **Secondary Data Collection methods**.

The syllabus of MHT CET includes four subjects - **Physics, Chemistry, Mathematics and Biology**. Candidates applying for engineering courses have to appear in the Mathematics part while those applying for pharmacy courses need to appear in the Biology part.

Graphs **help students organize and analyze information in well-structured formats, making it easier to interpret data**. Visual learners respond especially well to graphs and often understand the information better without pages of text.

A learning area is now referred to as **a subject**.

In Maths, there are **three major types of fractions**. They are proper fractions, improper fractions and mixed fractions. Fractions are those terms which have numerator and denominator. Based on these two terms we define its types.

They make four key assumptions: **ontological, epistemological, axiological, and methodological assumptions**.

**Causes of crime**

- Poverty. Poverty is one of the main reasons for crime.
- Peer Pressure. It is an established fact that peer pressure plays a significant role in the lives of all teenagers and young adults.
- Drugs. Crime and drug abuse are closely related.
- Politics.
- Religion.
- Background.
- Society.
- Unemployment.

To prepare a 20 mM solution **take 2.05 ml of your 30% solution and fill to 1 L with water (20 mM x 1000 ml / 9.79 M)**. If, however, the concentration of your stock solution is given as v/v = volume per volume, then Arvind is correct in calculating the molarity of the stock solution as 12.7 M.

**Monomers join together to make polymer chains by forming covalent bonds—that is, by sharing electrons.** **Other bonds then hold the groups of chains together to form a polymer material.**

An ideal first meal when weaning, soft scrambled egg is not only easy for baby to eat but also provides high quality protein and many important vitamins and minerals, including folate, vitamins B2 (riboflavin), B12, A and D, iodine, selenium, choline and long-chain omega-3 fatty acids. **Suitable from six months**.
