Step-by-step explanation:

A common difference is found in arithmetic sequences. The simplified formula for arithmetic sequences, which is what is used here, is [tex]a_{n}=dn-a_{0}[/tex]. Where d is the common difference and [tex]a_{0}[/tex] is the zeroth term. So, in the given equation 3 must be the common difference.

What is the Sine Rule?

The Law of Sines (also called the Sine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.

Triangle is a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry.

As per the given question, the given data  as:

A = 63

B = 56

C = 61 (because these angles should add up to 180)

c = 1/2

We know that the Sine Rule,

sin 63 / a = sin 61 / .5

a = 0.51 miles

sin 56 / b = sin 61 / .5

b = 0.47 miles

Therefore, the length 0.51 miles and 0.47 miles are the distances from each observer to the sailboat.

B: Without using a calculator, the square root of 18 will be between what two values (remember to look for perfect squares/perfect square roots)? Show your reasoning. You do not need to find the decimal equivalent of the root.

Answers

Step-by-step explanation:

√18 = √(2x9) = 3√2. so they pulled the 2 out of the square root incorrectly.

i need help getting how do i do this??

Answers

Answer:

5 units

Step-by-step explanation:

By distance formula:

[tex]r = \sqrt{(4 - 1) ^{2} + {(7 - 3)}^{2} } \\ \\ r = \sqrt{ {3}^{2} + {4}^{2} } \\ \\ r = \sqrt{9 + 16} \\ \\ r = \sqrt{25} \\ \\ r = 5[/tex]

Answer:

radius = 5 units

Step-by-step explanation:

The radius is the distance from the centre to a point on the circle.

Calculate r using the distance formula

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (4, 7)

r = [tex]\sqrt{(4-1)^2+(7-3)^2}[/tex]

  = [tex]\sqrt{3^2+4^2}[/tex]

   = [tex]\sqrt{9+16}[/tex]

   = [tex]\sqrt{25}[/tex]

   = 5

The perimeter of a rectangle is 90 feet, and the length is 32 feet. What is the width of the rectangle?
A. 26 feet
B. 13 feet
C. 58 feet
D. 15 feet

Answers

Length is 12ft, width is 4 ft.

2 x (length + width) = perimeter = 32 ft

⇒ length = 16ft - width [1]

length x width = area = 48 sq ft

Using [1] above:

⇒ (16ft - width) x width = 48 sq ft

multiplying out and rearranging:

⇒ width2 - 16 x width + 48 = 0

factorizing:

⇒ (width - 4)x(width - 12) = 0

Thus width = 4 or 12, so using [1] above:

⇒ width = 4ft, length = 16 - 4 = 12ft

or width = 12ft, length = 16 - 12 = 4ft

Convention is that the length is larger than the width, thus rectangle is 12ft long by 4 ft wide.

Answer:

15 ft

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. Pi approx A cylinder has a height of 20 yards and a diameter of 18 yards . What is its volume ?
