Does a triangle with sides of lengths 1.5 ft, 2.5 ft, and 2 ft form a right triangle? How do you know?

timama [110]

Answer:

Yes, the side lengths of 1.5, 2.5, and 2 ft form a right triangle.

Explanation:

Before we solve this problem, we need to know a couple of things.

In a right triangle, you have two legs and a diagonal line that goes from one leg to the other or from one side to the other. This line is called the hypotenuse. It is the longest side of a right triangle. This length can be calculated by using a special formula that is over a thousand years old.

The formula is called the Pythagorean Theorem.

The formula states that if you square one leg and the other leg and add it up. You get the side of hypotenuse which is squared as well.

Here it is in simple terms: $a^{2} +b^{2} =c^{2}$ .

a and b are your two legs.

C is your hypotenuse.

In this case 1.5 and 2 are your legs and 2.5 is your hypotenuse since it is the longest side.

Before we calculate, there is a converse to the Pythagorean Theorem.

If $a^{2} +b^{2} \neq c^{2}$ , then it is not a right triangle.

Lets make 1.5 for a

and 2 for b.

We know 2.5 is for c.

Here it is.

$1.5^{2} +2^{2} =2.5^{2}$ . The / means it is a fraction.

1.5 squared is 9/4 and 2 squared is 4. Add 4 and 9/4 and you get 25/4 squared. Take the square root of 25/4 and you get 5/2.

5/2 is equal to 2.5, so the Pythagorean Theorem applies to this triangle. Therefore, these side lengths do form a right triangle.

Hope this helps!

Write the application of computer in education and communication

daser333 [38]

Answer:

Technology has profoundly changed education in many ways. Technology has greatly expanded access to education. In medieval times, books were rare and only an elite few had access to educational opportunities. Individuals had to travel to centers of learning to get an education. Today, massive amounts of information (books, audio, images, videos) are available at one’s fingertips through the Internet, and opportunities for formal learning are available online worldwide through online learning, podcasts, traditional online degree programs, and more. Access to learning opportunities today is unprecedented in scope thanks to technology.

Technology is a gift of God. After the gift of life, it is perhaps the greatest of God's gifts. It is the mother of civilizations, of arts, and sciences. Technology has certainly changed the way we live. It has impacted different facets of life and redefined living. Undoubtedly, technology plays an important role in every sphere of life. Several manual tasks can be automated, thanks to technology. Also, many complex and critical processes can be carried out with ease and greater efficiency with the help of modern technology. Thanks to the application of technology, living has changed and it has changed for the better. Technology has revolutionized the field of education. The importance of technology in schools cannot be ignored. In fact, with the onset of computers in education, it has become easier for teachers to impart knowledge and for students to acquire it. The use of technology has made the process of teaching and learning all the more enjoyable.

Technology has also begun to change the roles of teachers and learners. In the traditional classroom, the teacher is the primary source of information, and the learners passively receive it. This model of the teacher as the “sage on the stage” has been in education for a long time, and it is still very much in evidence today. However, because of the access to information and educational opportunity that technology has enabled, in many classrooms today we see the teacher’s role shifting to the “guide on the side” as students take more responsibility for their learning using technology to gather relevant information. Schools and universities across the country are beginning to redesign learning spaces to enable this new model of education, foster more interaction and small group work, and use technology as an enabler.

Computers have drastically changed society over the last 20 years. How have computers affected communication in the business wor

iren2701 [21]

<u>Drastic change of over society Computers:</u>

In society computer has drastically changed and it has been used to for varies purpose to do analysis or storing data, as decisions making tools. Purpose computer been found is to do huge calculation. “Compute” word has been derived to computer. Computer later stage it diverted is purpose from calculation to information store device.

Computers have heavy effect the communication in normal word and business world. Especially social media took over the control of computers. In today’s world four type of ethical issue are known in computer mainstream in the workplace they are.

1. Crime (computer)

2. failure of responsibility in the computer.

3. Protection of software records and documents etc.

4. End user data protection and privacy.

99% of computers are protected with firewalls and antivirus. But still hackers can hack the computer and steal the data.

toThePowerOf is a function that accepts two int parameters and returns the value of the first parameter raised to the power of t

zlopas [31]

Answer:

cubeVolume = toThePowerOf(cubeSide, 3);

Explanation:

The line above accomplishes the task of calling the function toThePowerOf(). We are told in the question that the method accepts two int parameters these integer parameters are given as cubeSide and 3. They are passed as arguments when the method is called. The result of the function's computation is then assigned/stored to the the variable cubeVolume.
