Help me with a shortcut method of finding matrices using inverse method​

Answers

Answer 1

Answer:

There is no manual shortcut except you're using a program like MATLAB or Mathcad.

Otherwise the process still remains the same:

1. Find the determinant |a|

2. Find the minor, then find the cofactors C

3. Find the adjoint of a which is the transpose of C

4. Find the inverse with

[tex] \frac{1}{ |a | } \: \times adjoint \: of \: a[/tex]

Read the excerpts from “Take the Tortillas Out of Your Poetry” and “Speaking Arabic.”

My friend had concluded that if he took his language and culture out of his poetry, he stood a better chance of receiving a fellowship. He took out his native language, the poetic patois of our reality, the rich mixture of Spanish, English, pachuco and street talk which we know so well. In other words, he took the tortillas out of his poetry, which is to say he took the soul out of his poetry.

At a neighborhood fair in Texas, somewhere between the German Oom-pah Sausage Stand and the Mexican Gorditas booth, I overheard a young man say to his friend, “I wish I had a heritage. Sometimes I feel—so lonely for one.” And the tall American trees were dangling their thick branches right down over his head.

Answers

Answer:

1. A general report on raising children that is not  supported by data  → Faulty reasoning

Faulty reasoning in research refers to a scenario where the conclusion reached by a research is not supported by data which is the case in this scenario so it falls under Faulty reasoning.

2. An article talking only about the benefits of a  vegan diet and not potential drawbacks  → Omission.

In research, omission happens when important information is left out. It is usually done deliberately especially in situations where a certain narrative is being pushed so as to support that narrative.

3. A review about a company by an employee that  was fired from the company  → Bias

Bias has many forms but in this case means that the person interviewed might give a wrong impression of the company in order to spite them or get some sort of revenge for the company having fired them.

She’s lost her credit card. She _______ it somewhere.

Answers

she’s lost her credit card she LEFT it somewhere

She’s lost her credit card. She must have dropped it somewhere. The correct answer is option C.

The sentence suggests that the person has lost their credit card and the speaker is speculating about how it happened. The phrase "must have dropped" indicates a strong possibility or likelihood. It implies that dropping the credit card is the most reasonable explanation for the person losing it. The correct answer is option C.

Option a. "must have been dropping" is grammatically incorrect and does not convey the intended meaning.

Option b. "should have dropped" implies that dropping the credit card was the expected or appropriate action, but it does not express the likelihood that it actually happened.

Option d. "would have dropped" does not fit the context of the sentence and does not make logical sense in relation to losing a credit card.

Dear, Local Newspaper

I don't think this is a very great idea. If you guys would write the paper and express why it shouldn't be done, that would help a lot. If Casinos were built next to a learning environment, that would encourage more and more kids to gamble as adults. This is a bad influence, as they will lead up to terrible lives. Kids are at school to learn, and with a Casino nearby, this would interrupt this. It is highly inappropriate, and completely unnecessary. If the Casino happens to be robbed, what ensures that the students nearby will be safe. These are my biggest concerns.

I signed up for a national obstacle race.

In it there were around 7 km and more than 20 obstacles of all kinds, among which there were rivers to cross, fences to jump, ropes to climb, ramps, weight ...

Anyone would think that I am a running fan, but the reality is that running bores me a lot.

Why did I sign up then?

What called me about this race was the fact that I was able to overcome the different tests that were presented to me along the way. I wanted to test myself, physically and mentally. See how far he was able to go. My challenge was to finish the race without any injury, I was satisfied with that.

For a few months I was preparing myself with specific exercises that I had found on the internet. And it seems that the effort paid off because I did it!

The satisfaction I felt when crossing the finish line was brutal. I was exhausted, but full of adrenaline and energy. I just wanted to lay down on a couch and rest. Recover to… repeat again!

Explanation: I took the quiz.

The correct response is - She wants to give a specific example of how interconnected the various tree, bird, and beetle species are, and show how complicated their interactions become. Therefore option A is the correct response.

What is "The Thirsty Tree"?

Dams offered one solution, halting rivers in their tracks and preventing valuable water resources from disappearing into the sea. The grand sweep of Hoover Dam, completed in 1935, held enough space behind its bulk to store two years’ worth of the Colorado River’s flow.

Aquifers provided another source of water. Deep wells drew up rainwater stored between soil pores sometime in the Pleistocene era when mammoths still roamed the savannah-like plains of the Southwest. One option was the construction of dams, which would stop rivers in their tracks and save precious water resources from being lost to the sea.

Did you see( the / an) episode we talked about? 4. I have ( this/these) gloves , too. 5. There is (a / the) way to solve every problem. 6. I'll take this and you take ( this/ that).

Answers

Answer:

1-the

2-those

3-the

4-these

5-a

6-that

Explanation:

1-it's 'the' because there is more than 1 umbrella so you couldn't use 'a' in the sentence because that implies there is only 1. Also, 'a' wouldn't work because if it's in front of a vowel it has to change to 'an' so it wouldn't be grammatically correct.

2-sneakers is plural so it would be 'those'. 'That' is used if there is only one.

3-it would be 'the' because if you use 'an' it wouldn't read properly.

4-gloves is plural so you would use 'these'. 'This', again is singular so you would use 'these'.

5-it's 'a' because it is more general like if you use 'the' it would be suggesting theres a specific way.

6-it would be 'that' because if you say 'this' again you would be saying that somebody and you would be taking the same thing.
