Checking Statement I:

Using the above reference, we get the following arrangement:

Clearly, W is sitting second to the right of U.

Hence data in statement I is sufficient to answer the question.

Checking Statement II:

Using the above references, we get the following arrangement:

Clearly, W is sitting second to the right of U.

Hence data in statement II is sufficient to answer the question.

Here, the data in either Statement I or II alone is sufficient to answer the question.

A dot matrix printer is a type of printer that uses a matrix of small pins to create characters or images on paper. Let's analyze each statement to determine the correct answer:
i) Prints an entire line at a time: This statement is incorrect. A dot matrix printer prints one character at a time by striking an ink-soaked ribbon against the paper. It does not print an entire line at a time.
ii) Is a non-impact printer: This statement is incorrect. A dot matrix printer is an impact printer because it uses physical force to create the characters. The pins strike the ribbon, which transfers ink to the paper, resulting in the printed output.
iii) Allows multiple copies to be taken at a time: This statement is correct. Dot matrix printers have the ability to create multiple copies simultaneously. This is achieved by using carbon paper or carbonless paper, which allows the impact of the pins to transfer the image to multiple layers of paper.
iv) Prints one character at a time: This statement is correct. Dot matrix printers operate by individually striking pins against an ink-soaked ribbon to create characters. Each pin represents one dot, and the combination of dots forms the characters or images on the paper.
Based on the analysis above, the correct answer is C: iii and iv. A dot matrix printer allows multiple copies to be taken at a time and prints one character at a time.

Introduction:
In this question, we are asked to identify the characteristics of a laser printer. We need to choose the correct options from the given choices.
Characteristics of a laser printer:
A laser printer is a type of printer that uses laser technology to produce high-quality prints. Let's analyze each statement given in the question and determine its accuracy:
1. Prints an entire line at a time:
- This statement is true. Laser printers use a process called "electrophotography" or "xerography" to print an entire line at a time. This process involves the use of a laser beam to create an electrostatic image of the entire line on a photosensitive drum.
- Correct
2. Non-impact printer:
- This statement is true. Laser printers are non-impact printers, which means they do not require direct contact between the print head and the paper to create an image. Instead, they use a laser beam to transfer toner onto the paper.
- Correct
3. Allows multiple copies to be taken at a time:
- This statement is false. Laser printers generally do not allow multiple copies to be taken at a time. However, some advanced laser printers may have features like duplex printing or collating, which can produce multiple copies in a single print job.
- Incorrect
4. Prints one character at a time:
- This statement is false. Laser printers do not print one character at a time. As mentioned earlier, they print an entire line at a time using a laser beam and electrostatic imaging.
- Incorrect
Conclusion:
Based on the analysis, we can conclude that the correct characteristics of a laser printer are:
- Prints an entire line at a time
- Non-impact printer
Therefore, the correct answer is (A) i and ii.

The teacher should provide an overview of the main points before launching into the body of the speech. This tunes the mind of the students to capture information, which the teacher is about to provide to the students. The overview helps creating interest in the subject being taught, and the student anticipates things which he is about to learn, along with the combination of his previous knowledge and experience.

In triangle OAB

OA = OB (radius of a circle)

∠OAB = ∠OBA

∠OBA = 40º (angles opposite to equal sides are equal)

Using the angle sum property

∠AOB + ∠OBA + ∠BAO = 180º

Substituting the values

∠AOB + 40º + 40º = 180º

By further calculation

∠AOB + 80º = 180º

∠AOB = 180º - 80º

∠AOB = 100º

As the angle subtended by an arc at the centre is twice the angle subtended by it at the remaining part of the circle

∠AOB = 2 ∠ACB

Substituting the values

100º = 2 ∠ACB

Dividing both sides by 2

∠ACB = 50º

Therefore, ∠ACB is equal to 50º.

Solution: From equation (i) x = 14 - 4y ....(iii)

Substitute the value of x in equation (ii)

⇒ 7 (14 - 4y) - 3y = 5

⇒ 98 - 28y - 3y = 5

⇒ 98 - 31y = 5

⇒ 93 = 31y

⇒ y = 93/31

⇒ y = 3

Now substitute value of y in equation (iii)

⇒ 7x - 3 (3) = 5

⇒ 7x - 3 (3) = 5

⇒ 7x = 14

⇒ x = 14/7 = 2

So the solution is x = 2 and y = 3

Since if a circle inscribed a square. then the radius of the circle is half of to side of square.
∴  Radius = 10/2 = 5 cm
∴ Area of the circle = πr² = π(5)² = 25π sq. cm 

Ignoring a leap year, both Ram and Shyam can have any day of the year as their birthday. 
∴ Total number of possible ways in which their birthday can fall = 
Also they can share the same birthday falls on same date = 365
∴ Required Probability 

Let AB be the broken part of the tree.

Therefore, the length of the broken part of the tree is 20/√3 meters.

A sector is region which lies between an arc and two radii joining the extremities of the arc and the centre.

The shaded region denotes the sector of a circle. The unshaded part is also a sector.

Notice that it is enclosed by two radii and an arc.

tan 1.tan 2.tan 3...tan (90 - 3 ).tan ( 90 - 2 ).tan ( 90 - 1)

=tan 1.cot 1.tan 2.cot 2.tan 3.cot 3 ... tan 89.cot 89 
1 x 1 x 1 x 1 x ... x 1 =1

 

⇒ p(x) = x²−3x−10
But we know that, if we multiply or divide any polynomial by any arbitrary constant. Then, the zeroes of the polynomial never change.
Therefore,

p(x)=kx²−3kx−10

 Where,k is a real number

Hence, the required number of polynomials having zeros −2 and 5 are infinite i.e. more than 3.

On Y-axis, x-co-ordinate is zero.

Formula for finding the roots of a quadratic equation is

So since 
b² - 4ac = 0, putting this value in the equation

So there are repeated roots

2x² + 3 + 2√6x + x² = 3x² - 5x
3 + 2√6x + 5x= 0

Which is not a quadratic equation.

Learning disability refers to a neurological disorder that causes cognitive impairment. Dyslexia, dysgraphia, dyscalculia, etc are the most common learning disability.

'Dyscalculia' is a type of mathematics-related learning disability which:

• hinders learner's basic understanding of numbers.

• affects learner's ability to perform mathematical calculations.

• makes learners unable in identifying mathematical symbols like +, ×,>, etc.

Key Points

Learning disabilities related to mathematics:

• It is intrinsic and due to central nervous system dysfunction.
• It is a variable state which can be addressed by appropriate comprehensible input.
• It can't be attributed to cultural deprivation as it can present in children of any culture.

• It can't be attributed to educational deprivation as it can also present in children with average or above-average IQ.
• It is generally found in children whose parental relatives have such problems as it can passed from one generation to another.

Hence it could be concluded that learning disabilities related to mathematics are generally found in those children whose parental relatives have such problems.

⇒ x²+ 5x - 6 = 0

⇒ x²+ 6x -x - 6 = 0

⇒ x(x+6) -1(x+6) = 0

⇒ (x-1) (x+6) = 0

⇒ x = 1, -6

 

The correct answer is a.

From the polynomial we get,

α + β = - b/a = -(-5/15) = 1/3

αβ = c/a = (6/15) = 2/5

To find: (1+1/α) (1+1/β)...... (taking L.C.M) 

= (α+1/α) (β+1/β) ....(simplifying brackets)

= αβ + α + β + 1 / αβ

=( 2/5 + 1/3+ 1)  /  2/5 

=26/15 X 5/2 = 13/3

Synonym of Diatribe: - The correct option is: B: Tirade. Explanation: - Both "diatribe" and "tirade" refer to a long, angry, and critical speech or piece of writing that strongly criticizes someone or something. - The other options are not synonyms of "diatribe" for the following reasons: - A: Debate refers to a formal discussion on a specific topic in which opposing arguments are put forward. - C: Monologue refers to a long speech by one person, especially in a play, movie, or as part of a theatrical performance. - D: Oration refers to a formal, usually ceremonial, speech delivered in public.
