what is the sum of the complex numbers 6+2i and 3+5i, where i=sqrt(-1)

Answers

Answer 1

Answer:

The sum of the complex numbers is [tex]9+i\,7[/tex].

Explanation:

Let be [tex]u = 6 + i\,2[/tex] and [tex]v = 3 + i\,5[/tex], the sum of the complex number can be found by algebraic means. That is:

1) [tex]u = 6 + i\,2[/tex], [tex]v = 3 + i\,5[/tex] Given.

2) [tex]u+v = (6+i\,2)+(3+i\,5)[/tex] Definition of addition.

3) [tex]u+v = (6+3) + (2\,i + 5\,i)[/tex] Commutative and associative properties.

4) [tex]u+v = 9 + (2+5)\,i[/tex] Definition of addition/Distributive property.

5) [tex]u + v = 9 + i\,7[/tex] Definition of addition/Commutative property/Result.

The sum of the complex numbers is [tex]9+i\,7[/tex].

Difficult concepts in The Medawar Lecture 1998 Is science dangerous

Answers

The Medawar Lecture 1998 addresses the concern about the danger of science. Sir Peter Medawar, who was the Nobel Prize-winning immunologist, was known to make his lectures about topics that were outside his field of expertise, and this lecture was no exception.


Science has been responsible for some of the most significant advancements in the history of humanity. Medicine, agriculture, and technology are just a few examples of fields where science has brought us significant progress. However, science can also be used for destructive purposes. For example, the atomic bomb was developed through scientific research. This technology has the power to wipe out entire cities, and it has been used for that purpose in the past.
In conclusion, science is not inherently dangerous, but it can be used for dangerous purposes. The responsibility lies with the people who use it. It is up to scientists and policymakers to ensure that science is used for the greater good and not for evil.

Which of the following explains the importance of the English Bill of Rights? (4 points) a It created a constitutional monarchy. b It gave the nobles total control. c It gave the king or queen more power. d It made the parliament weaker.

Answers

Answer:

a) It created a constitutional monarchy.

The correct answer explaining the importance of the English Bill of Rights is  It created a constitutional monarchy.

The correct answer to the given question is a.

The English Bill of Rights, enacted in 1689, was a pivotal document that established important principles and rights in the governance of England. It played a crucial role in shaping the political landscape and establishing the foundation of constitutional monarchy in England.

The Bill of Rights limited the powers of the monarchy and affirmed the supremacy of Parliament. It outlined several key provisions that protected the rights of individuals and defined the relationship between the monarchy and the governed. These provisions included the right to petition the king or queen, freedom of speech and debate in Parliament, and protection against cruel and unusual punishment, among others.

By establishing a constitutional monarchy, the English Bill of Rights helped ensure that the monarch's power was limited and balanced by the authority of Parliament. It set the precedent that the monarch's authority derived from and was subject to the law, and that the government should operate within the framework of a written constitution.

The creation of a constitutional monarchy through the English Bill of Rights laid the groundwork for the development of modern democratic principles, the protection of individual rights, and the idea of limited government. It served as an influential model for later constitutional developments in other countries, including the United States.

Question 11 options:

A)

x = 40

B)

x = 135

C)

x = 90

D)

x = 45

Answers

Since this is an isosceles triangle, that means that x, and the angle opposite from x, are the same. We take 135° and subtract that from 180°. That gives us 45°. Since the angle opposing x is 45°, then x is 45° as well.



So your answer is 45

x is 45

the angle right above 135 is the same as x, and the angle above 135 is 45
