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].

Incremental development is a method of writing function codes that avoids lengthy debugging sessions by writing each line of complete code and executing it so that before moving on to the next stage of development, the previous stage has been successfully executed.

The process methodology of incremental development in software engineering emphasizes the benefits of moving slowly toward a goal.

In contrast to the waterfall model of software development, where a functioning system is made available only during the final stages of the project, incremental development starts with a small, functional system that is gradually enhanced and expanded.

The Python function hypotenuse() is provided below:

Stage 1:Creating the skeleton of the function and testing the function code

def hypotenuse(base, per):

  return 0.0

print(hypotenuse(3, 4))

Output:

0.0

Stage 2:Insert the hypotenuse calculation expression and output the result to the console.

import math

def hypotenuse(base, per):

h=math.sqrt(base ** 2 + per ** 2)

print(h)

hypotenuse(3, 4)

Output:

5

Stage 3:Finally, finish the function by adding the return expression.

import math

def hypotenuse(base, per):

h=math.sqrt(base ** 2 + per ** 2)

return h

print(hypotenuse(3, 4))

Output:

5

Stage 4:The function is called with the additional two arguments:

import math

def hypotenuse(base, per):

   h=math.sqrt(base ** 2 + per ** 2)

   return h

print("The hypotaneous is: "+str(hypotenuse(3, 4)))

print("The hypotaneous is: "+str(hypotenuse(12, 5)))

print("The hypotaneous is: "+str(hypotenuse(6, 8)))

Output:

The hypotaneous is: 5.0

The hypotaneous is: 13.0

The hypotaneous is: 10.0

3 collections like HashMap, ArrayList and Vector to insert the key values are=

HashMap: A HashMap is an unordered collection that stores key-value pairs, where each key is unique. It provides

constant-time complexity for insertion of key-value pairs, which is O(1).

ArrayList: An ArrayList is an ordered collection that stores values. It has constant-time complexity for insertion of

values, which is O(1). However, if the key needs to be associated with the value, then two ArrayLists must be used in

order to store the key and value separately. This means that the insertion of a key-value pair would take O(2).

Vector: A Vector is an ordered collection that stores values. It has constant-time complexity for insertion of

values, which is O(1). However, if the key needs to be associated with the value, then two Vectors must be used in

order to store the key and value separately. This means that the insertion of a key-value pair would take O(2).

What is collection?

Collection is a term used to describe a group of items or objects that have been gathered together. It is a term that is commonly used in many different areas such as art, literature, music, fashion and even biology.

The integrity of a program's output heavily depends on its input's integrity. The program may produce incorrect or unexpected results if the input is invalid or incorrect. Therefore, it is often important for a program to validate its input and discard invalid data. This can help ensure that the program produces reliable and accurate output.

However, there may be situations where it is not practical or necessary to validate all input or where the consequences of invalid input are not significant. In these cases, discarding invalid input may not be necessary and prompt the user to enter the correct data. It is important to consider the specific requirements and constraints of the program and the potential impact of invalid input on the program's output.

It is often easier to maintain data in a datasheet using a form because all changes for a Single Record are the focus at one time.

Records. A Tuple, Record, or Row is a single entry in a table. In a table, a tuple represents a collection of connected data. As a result, Option 1 is right. A record is a horizontal collection of information in a database; the content of those fields is unique to that row.

The most frequent technique to utilize sub-forms is that the main form only displays one record at a time – in a “form” view, not a datasheet view. The sub-forms exhibit all the records on the many side of a one-to-many connection with the main form’s single record.

Explanation:

If I had to buy, let’s say an iPad, I would visit the official store. First of all, I would take a closer look at the product, revising it carefully, if it feels right and if it meets my needs. Then I would ask for the price if they have a discount or any sale upcoming or payment plan. If everything meets my requirements I would buy the item. On the other hand, if there weren’t any official stores around the place I live in, I would visit three different department stores, preferably where they have the product of my interest displayed, also I would ask about the price and/or payment plan or discounts and availability. I must mention that cost is an important aspect to make a decision on where to buy the item. All of this process would take about 1 or 2 days at most.

Advantages

-You can see, feel, check the product to dissipate any doubts, there are people willing to answer any question and help to make a better choice.  

Get the product at the same moment you are paying for it and if you want to you can use/wear it immediately.

Disadvantages

If they are out of stock of the item of your interest, there is a chance you will have to wait a long time for it, although it could happen the store won’t have the product available again.  

The offers are not as wide as on the web sites.

Shopping on the web or via a mobile app

It is almost the same as shopping in a traditional manner, the greater differences are that there are more virtual places/shops online to compare prices and availability and sometimes they have great offers, because of the competition. Generally, the items are cheaper than a department store.

This process could take about a week, especially if you are waiting for a specific offer.

Advantages

There are lots of options, lots of different online stores, that increase the chances to get a good offer or an item with better characteristics at the same price; if you don’t find availability in one web you can find it in another in no time.

There is no need to leave your house or put on pause your busy schedule, as you will receive the item at your door.

Disadvantages

You can’t check the product given they only display a few pictures of it and a brief description, there is no one to answer your doubts about the item, basically, the decision relies on your research and recommendations of the product.

After making your purchase, you will have to wait a few days to receive your item at home or the workplace. Sometimes happens the store confuses your order sending a different product or other with different characteristics, resulting in having to return the item and wait days to get what you order in the first place.

Explanation:

Which did I prefer and why?

Considering the advances in technology, I prefer to shop online, there I can find what I'm looking for and of course, they have a great offers, too. Besides, with day to day occupations I barely have time to go to a department store, so is easier to access using a computer or an app on the smartphone.
