1. Trend Analysis (5 Marks)
Trend analysis is a financial tool used to study the direction of business performance over a period of time. It compares financial data (such as sales, profit, expenses, assets) from several years to identify whether they are increasing, decreasing, or remaining stable. It is useful because it highlights long-term patterns rather than one-year changes.
Key features:
Shows growth or decline over time
Helps in planning and forecasting
Makes year-to-year comparison easier
Helps
Work:
The product of force and displacement in the direction of the force.
Important ideas
No displacement → no work
Force perpendicular to motion → no work
W = Fd
Units: Joules (J)
Power:
The rate at which work is done or energy is transferred.
P = \frac{W}{t}
Units: Watts (W)
Energy:
The ability to do work.
Energy can change forms but total energy remains constant (Conservation of Energy).

A bill of exchange is a written instrument containing an unconditional order given by one person to another person directing him to pay a certain sum of money to a specified person or to the bearer of the instrument. It is an important negotiable instrument governed by the Negotiable Instruments Act, 1881.
For a document to be considered a valid bill of exchange, the following essential elements must be present:

A Finite Automaton (FA) is a mathematical model of computation used to recognize regular languages. It consists of a finite number of states and transitions between those states based on input symbols.
Formally,
FA = (Q, Σ, δ, q₀, F)
Where:
Q = finite set of states
Σ = input alphabet
δ = transition function
q₀ = initial state
F = set of final (accepting) states
A Deterministic Finite Automaton (DFA) is a finite automaton in which each state has exactly one transition for each input symbol.
1. Define Strategic Alliance (with example)
A strategic alliance is a partnership between two or more companies where they share resources, skills, or technology to achieve a common goal while remaining independent.
Example: A food delivery app partnering with a payment wallet company to offer cashback to users.
2. Define "Merger" (with example)
A merger is when two companies combine to form one new company for better performance, resources, or market advantage.
Example: If Company A and Company B join
Co-relation
Artificial Intelligence (AI), Machine Learning (ML), and Deep Learning (DL) are interconnected fields, each building upon the other, but they are not synonymous. AI is the broader concept of machines being able to carry out tasks in a way that we would consider "intelligent." ML is a subset of AI that focuses on the development of algorithms that allow computers to learn from and make predictions or decisions based on data. DL is a subfield of ML that focuses on artificial neural
