The statement  on the absolute minimum value is False.

Absolute Minima and Maxima:

We occasionally encounter operations with hills and valleys. Hill and valley points in polynomial functions typically have many locations. We are aware that these places, which can be categorized as maxima or minima, are the function's crucial points. The valley points are referred to as minimas and the hill points as maxima. We must determine the locations of the function's global maxima and global minima, which are known as the minimum and maximum values, respectively, due to the fact that there are several maxima and minima.

Critical Points:

When the derivative of a function f(x), for example, reaches 0, those locations are said to be its crucial points. Both maxima and minima are possible for these places. The second derivative test determines if a crucial point is a minima or maximum. Since the derivative of the function might occur more than once, several minima or maxima are possible.

Extrema Value Theorem:

Under specific circumstances, the extrema value theorem ensures that a function has both a maximum and a minimum. Although this theorem just states that the extreme points will occur, it does not specify where they will be. The theorem asserts,

If a function f(x) is continuous on a closed interval [a, b], then f(x) has both at least one maximum and minimum value on [a, b].

A surplus in a balance of payments is usually beneficial.

The correct answer to the given question is option B.

A surplus in a country's balance of payments occurs when its exports exceed its imports, resulting in a positive net inflow of foreign exchange. This surplus can bring several benefits to the country's economy. Firstly, it indicates that the country is competitive in international trade, as it is able to export more goods and services than it imports. This can boost domestic industries, create jobs, and enhance economic growth.

Secondly, a surplus in the balance of payments can contribute to increased foreign exchange reserves. These reserves can be used to stabilize the country's currency, provide a buffer against external shocks, and facilitate international transactions. Higher foreign exchange reserves can also enhance investor confidence and attract foreign direct investment.

However, it is important to note that while a surplus is usually beneficial, excessive surpluses can have some drawbacks. A persistent surplus can lead to an accumulation of foreign reserves beyond what is necessary, potentially causing imbalances and inefficiencies in the economy. It can also create trade tensions with other countries and contribute to global imbalances.

In summary, a surplus in the balance of payments is generally beneficial for a country's economy, but it should be managed and monitored to ensure sustainable economic growth and stability.

It uses primary keys and foreign keys as a means to provide efficient access to data and is supported directly in the database rather than maintained in the application code.

Explanation: Relational databases use an expressive query language, make efficient use of indexes within the database, ensure strong consistency, and fit well within an enterprise management system. Non-relational databases have a flexible data model, have high scalability, and performance, and have always-on global deployments.

The statement which describes a key feature of a relational database is that it uses primary keys and foreign keys as a means to provide efficient access to data and is supported directly in the database rather than maintained in the application code. Thus, the correct option for this question is D.

A relational database may be defined as a collection of information that organizes data in predefined relationships where data is stored in one or more tables or relations of columns and rows, making it easy to see and understand how different data structures relate to each other.

The key features of a relational database may include atomicity, consistency, isolation, durability, data consistency, flexibility, togetherness, data sharing, independence, etc. Each relation (table) must have a unique field that describes each record. This unique field is called a primary key.

The iterations that are performed in each algorithm for the function is 5.

Binary search algorithms run faster because of their searching way is based on divide and conquer technique

An algorithm is a limited set of precise instructions that are usually applied to carry out a computation or solve a group of related problems. Calculations and data processing are done according to specifications called algorithms.

Case 1:  Linear Search

The number of Iterations is 5, and the returned index value will be 4,  that is the after 4th Iteration(that is at 5th) the array element will be matched with the searching element

Case 2: Binary Search

The number of Iterations is 3, and the returned index value will be 4,  that is the after 2nd Iteration (that is at 3rd )the array element will be matched with the searching element.

Because there are fewer iterations in the Binary Search algorithm than there are in the Linear Search algorithm, it operates more quickly.
