Why is the cost of a software project not directly related to the cost of development?

1 answer:

8 0

Answer:On average, the cost of a robust custom software project will range between $50,000 and $250,000, although some sources say the price of a hypothetical mobile app built by a large development company may reach $1,000,000.

Using Matlab programming I need to rotate the line defined by x,y by 45 degrees around 2,2

belka [17]

Answer:

% here x and y is given which we can take as

x = 2:2:10;

y = 2:2:10;

% creating a matrix of the points

point_matrix = [x;y];

% center point of rotation which is 2,2 here

x_center_pt = x(2);

y_center_pt = y(2);

% creating a matrix of the center point

center_matrix = repmat([x_center_pt; y_center_pt], 1, length(x));

% rotation matrix with rotation degree which is 45 degree

rot_degree = pi/4;

Rotate_matrix = [cos(rot_degree) -sin(rot_degree); sin(rot_degree) cos(rot_degree)];

% shifting points for the center of rotation to be at the origin

new_matrix = point_matrix - center_matrix;

% appling rotation

new_matrix1 = Rotate_matrix*new_matrix;

Explanation:

We start the program by taking vector of the point given to us and create a matrix by adding a scaler to each units with repmat at te center point which is (2,2). Then we find the rotation matrix by taking the roatational degree which is 45 given to us. After that we shift the points to the origin and then apply rotation ans store it in a new matrix called new_matrix1.

Why do software developers prefer to use high-level language to author programs?

Charra [1.4K]

Answer:

The answer to this question is given below in the explanation section

Explanation:

The correct answer to this question is: it used a more English-like syntax.

The software developer use high-level language to develop or author the program because it is more likely to English syntax and it would be easy for a software developer to author a program easily instead of using low level language and remembering ones and zeros.

Other options are not correct because:

It can be used on computers without microprocessors: Each computer has a microprocessor either you develop a program using high-level or low-level languages. Changes and modifications are easy in high-level language than in low-level languages. so, the option that prevents anyone from making changes to the software later is wrong. However, high-level languages are less complicated in learning and in authoring the programs but it does not use zeros and ones, it uses English-like syntax. So, the last option is also wrong.

3.1.2 Quiz: What Can Information Technology Do for You? Question 8 of 10 What is one reason why a business may want to move enti

balu736 [363]

Answer:

C. To focus on a global market

Explanation:

Information technology can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.

An information technology interacts with its environment by receiving data in its raw forms and information in a usable format.

Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information technology and systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information technology and systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.

Additionally, an information system or technology comprises of five (5) main components;

1. Hardware.

2. Software.

3. Database.

4. Human resources.

5. Telecommunications.

Hence, information technology or system relies on the data it receives from its environment, processes this data into formats that are usable by the end users.

One reason why a business may want to move entirely online is to focus on a global market through the use of social media platforms and networks to reach out to customers in various geographical location.

“The software crisis is aggravated by the progress in hardware technology?” Explain with examples

exis [7]

Answer:

Basically, dealing with the "software crisis" is what we now call software engineering. We just see the field more clearly now.

What this crisis was all about is that in the early days of the modern technological era -- in the 1950s, say -- there was tremendous optimism about the effect that digital computers could have on society, on their ability to literally solve humanity's problems. We just needed to formalize important questions and let our hulking "digital brains" come up with the answers.

Artificial intelligence, for example, had some early successes in easy to formalize domains like chess and these sorts of successes led to lots of people who should have known better making extremely naive predictions about how soon perfect machine translation would transform human interaction and how soon rote and onerous work would be relegated to the dustbin of history by autonomous intelligent machines.

For a Know Simple query, a Fully Meets rating can be given if the result does not display the answer, but it is at the very top

tekilochka [14]

Answer:

For a Know Simple query, a Fully Meets rating can be given if the result does not display the answer, but it is at the very top of the landing page.

B) False

Explanation:

A know simple query is special form of a know query. The query which are intended to know something like what is the length of pitch of a cricket ground?
A know simple query is such a know query that can be described in very little amount of words.
A know simple query would only get the fully meet ratings if the result shown has the result in a special result block or it is shown upfront. You don't need to open a link to get the answer in such scenario.
