Find the difference of the complex numbers.
(2 +8i)-(-5 - 3i)

Answers

Answer:

7 + 11i

Step-by-step explanation:

Simplify: (2 +8i)-(-5 - 3i) = 2 + 8i + 5 + 3i

Add real numbers to real numbers and imaginary to imaginary: 2 + 8i + 5 + 3i = 7 + 11i

A complex number can be shown as a pair of integers (a, b). The difference of the complex number (2 +8i)-(-5 - 3i) is 7+11i.

What is a complex number?

A complex number can be shown as a pair of integers (a, b) forming a vector on an Argand diagram, which represents the complex plane.

The difference of the complex number can be done as following,

(2+8i)-(-5-3i)

= 2 + 8i + 5 + 3i

= 5+2 + 8i+3i

= 7 + 11i

Hence, the difference of the complex number (2 +8i)-(-5 - 3i) is 7+11i.

AABChas coordinates A (-4,-2), B(0,4), and C(4,-2). Find the midpoint of AC.

Answers

Answer:

( 0, - 2 )

Step-by-step explanation:

Mid point formula : -

( x1 + x2 ) / 2, ( y1 + y2 ) / 2

Here,

Let ( x1, y1 ) = ( - 4, - 2 )

Therefore,

x1 = - 4

y1 = - 2

Let ( x2, y2 ) = ( 4, -2 )

Therefore,

x2 = 4

y2 = - 2

Midpoint of AC

= ( - 4 + 4 ) / 2, ( - 2 - 2 ) / 2

= ( 0 / 2, - 4 / 2 )

= ( 0, - 2 )

The midpoint of AC is ( 0, - 2 ) when coordinates of A (-4,-2), B(0,4), and C(4,-2) is given.

What is the Midpoint of a Line?

The midpoint of a line is a point that is equidistant from the endpoints of the line and in the middle of the line. If the endpoints of the line are (x)1, (y)1, and (x)2, (y)2, then the formula for the midpoint of the line is {[(x)1 + (x)2]/2, [(y)1 + (y)2]/2}.

Mid point formula is given as : -

( x1 + x2 ) / 2, ( y1 + y2 ) / 2

Here,

Let ( x1, y1 ) = ( - 4, - 2 )

x1 = - 4

y1 = - 2

Let ( x2, y2 ) = ( 4, -2 )

x2 = 4

y2 = - 2

now using Midpoint formula to find the coordinates of AC

= ( - 4 + 4 ) / 2, ( - 2 - 2 ) / 2

= ( 0 / 2, - 4 / 2 )

= ( 0, - 2 )

Therefore, the midpoint of AC is ( 0, - 2 )

Answers

Answer:

-25 and 4

Step-by-step explanation:

Two numbers that multiply to the value on top and add to the value on bottom

Value on top = -100

Value at bottom = -25

Numbers that multiply to give -100 = -10 × 10, -20 × 5, -25 × 4, - 50 × 2,

Of all the above, - 25 × 4 = -100

-25 + 4 = -21

Value at bottom = -25

Therefore, the two numbers are -25 and 4

-25 × 4 = -100

-25 + 4 = -21

I am being timed!31 POINTS!!!!!!!!!!!!!!!!!!Which sentence in this excerpt shows that Tom Canty is not satisfied with being a mock (pretend) prince?By-and-by Tom's reading and dreaming about princely life wrought such a strong effect upon him that he began to act the prince, unconsciously. His speech and manners became curiously ceremonious and courtly, to the vast admiration and amusement of his intimates. A) But Tom's influence among these young people began to grow now, day by day; and in time he came to be looked up to, by them, with a sort of wondering awe, as a superior being. He seemed to know so much! and he could do and say such marvellous things! and withal, he was so deep and wise! Tom's remarks, and Tom's performances, were reported by the boys to their elders; and these, also, presently began to discuss Tom Canty, and to regard him as a most gifted and extraordinary creature. Full-grown people brought their perplexities to Tom for solution, and were often astonished at the wit and wisdom of his decisions. B) In fact he was become a hero to all who knew him except his own familythese, only, saw nothing in him.Privately, after a while, Tom organised a royal court! He was the prince; his special comrades were guards, chamberlains, equerries, lords and ladies in waiting, and the royal family. Daily the mock prince was received with elaborate ceremonials borrowed by Tom from his romantic readings; daily the great affairs of the mimic kingdom were discussed in the royal council, and daily his mimic highness issued decrees to his imaginary armies, navies, and viceroyalties.After which, he would go forth in his rags and beg a few farthings, eat his poor crust, take his customary cuffs and abuse, and then stretch himself upon his handful of foul straw, and resume his empty grandeurs in his dreams.C) And still his desire to look just once upon a real prince, in the flesh, grew upon him, day by day, and week by week, until at last it absorbed all other desires, and became the one passion of his life.One January day, on his usual begging tour, he tramped despondently up and down the region roundabout Mincing Lane and Little East Cheap, hour after hour, bare-footed and cold, looking in at cook-shop windows and longing for the dreadful pork-pies and other deadly inventions displayed therefore to him these were dainties fit for the angels; that is, judging by the smell, they werefor it had never been his good luck to own and eat one. There was a cold drizzle of rain; the atmosphere was murky; it was a melancholy day. At night Tom reached home so wet and tired and hungry that it was not possible for his father and grandmother to observe his forlorn condition and not be movedafter their fashion; wherefore they gave him a brisk cuffing at once and sent him to bed. D) For a long time his pain and hunger, and the swearing and fighting going on in the building, kept him awake; but at last his thoughts drifted away to far, romantic lands, and he fell asleep in the company of jewelled and gilded princelings who live in vast palaces, and had servants salaaming before them or flying to execute their orders. And then, as usual, he dreamed that he was a princeling himself. PLEASE HELP ASAP NO LINKS PLEASE An employee works as a veterinary assistant at a clinic making $31,840 per year.
