If you fold the paper in upward direction from dotted line, the upper line of the figure will be near to middle line. So it will make s triangle. Please take a transparent paper and draw a similar figure and fold it.

As short form of 'Mountain' is 'Hill' similarly 'Tank' is short form of 'River'.

All are the parts of tree.

Here, Area of circle (A) = πr² and Circumference of circle (C) = 2πr
 
Putting value of C in A = πr², we get

In Δ PSR and ΔPQR

► PR = PR
► ∠ 1 = ∠ 2 
► ∠ 3 = ∠ 4

Δ PSR ≅ Δ PQR  [ASA]

► PS = PQ   [CPCT]
► QR = RS  [CPCT]

The correct option is Option A

Use tanθ formula in both the triangles ABC and ABD.

Let AB be the tree and AP be the shadow.
Let AB = x meters. Then AP = x√3 meters
Also ∠APB = θ
In right angled triangle ABP 

Therfore the angle of elevation of the Sun is 30°.

we know sin(90 - a) = cos(a) 

cos(90 - a) = sin(a)

sin(a) = 1/cosec(a)

sec(a) = 1/cos(a)

cos40 = cos(90-50) = sin50

cosec40 = cosec(90-50) = sec50

so our expression becomes

sin50/sin50 + sec50/sec50 - 4cos50 / sin40

= 1 + 1 - 4(1)   since cos50 = sin40

= -2

The correct answer is Performance Evaluation.

Key PointsThe activity of evaluating whether tasks are completed and goals are achieved is commonly termed as "Performance Evaluation" or "Performance Management." This process involves assessing the performance of individuals, teams, or organizations against predetermined objectives, standards, or benchmarks. Performance evaluation typically includes reviewing progress, identifying areas of strength and areas needing improvement, providing feedback, and making adjustments as necessary to ensure that goals are met effectively and efficiently. Performance evaluation is a fundamental aspect of management and organizational effectiveness, helping to drive continuous improvement and accountability within the organization.

Additional Information

• Purpose: The primary purpose of performance evaluation is to assess the performance of individuals, teams, or entire organizations to determine how effectively they are meeting their goals and objectives. Performance evaluation provides valuable feedback that can be used to improve performance, identify areas for development, and make informed decisions about resource allocation and strategic planning.
• Process: Performance evaluation typically involves a systematic process of setting performance objectives, monitoring progress, evaluating performance against predetermined criteria or standards, providing feedback, and making adjustments as necessary. This process may include various tools and methods such as performance appraisals, self-assessments, peer evaluations, and 360-degree feedback.
• Criteria: Performance evaluation criteria may vary depending on the nature of the work and the goals of the organization. Common criteria include productivity, quality of work, adherence to deadlines, teamwork, communication skills, customer satisfaction, and adherence to organizational values or ethics.
• Feedback: Effective performance evaluation provides timely and constructive feedback to individuals or teams about their performance. Feedback should be specific, objective, and focused on behaviors or outcomes that can be improved. Positive feedback can reinforce desired behaviors, while constructive criticism can help individuals identify areas for growth and development.
• Performance Improvement: Performance evaluation is not only about assessing past performance but also about driving future improvement. It serves as a basis for setting goals, identifying training or development needs, and implementing strategies to enhance performance. By regularly evaluating performance and providing feedback, organizations can foster a culture of continuous improvement and accountability.
• Legal and Ethical Considerations: Performance evaluation processes must be conducted in a fair, unbiased, and transparent manner to ensure legal compliance and protect the rights of employees. Evaluations should be based on job-related criteria and conducted without discrimination or favoritism. Confidentiality and privacy should also be maintained throughout the process.

Overall, performance evaluation is a vital management process that helps organizations assess, manage, and improve performance to achieve their goals and objectives effectively. It provides a mechanism for accountability, feedback, and continuous improvement, contributing to the success and sustainability of the organization

a₂₁ -a₇ = {a + (21 - 1)d}

- {a + (7 - 1)d} = 84

a + 20d- a - 6d = 84

14d = 84

d = 18/14 = 6

d = 6

So, A is incorrect but R is correct

Concentric circles are circles with a common center. The region between two concentric circles of different radii is called an annulus.
Any two circles can be made concentric by inversion by picking the inversion center as one of the limiting points.

Product of Zeroes

⇒ k² – 4k + 4 = 0

⇒ (k – 2)² = 0 ⇒ k = 2

l = 2 x 5 = 10 cm , b = 5 cm

and h = 5 cm

Total surface area = 2(lb + bh + lh)

= 2(10 x 5 + 5 + 5 x 10 x 5)

= 2 x 125 = 250 cm²

The expansion of (2a - 3b + 5c)² -: (2a)² + (- 3b)² + (5c)² + 2× 2a × (-3b) + 2× (-3b)× 5c + 2× 5c + 2a. = 4a² + 9b² + 25c² - 12ab - 30bc + 20ac

Let the radius of the circle be r and side of the square be a.
Then, according to question,
2πr = 4a

Now, ratio of their areas,

Therefore, Area of the circle > Area of the square
