Answer 1

Answer:

See below, please

Step-by-step explanation:

We know

[tex]f(x) = {x}^{2} + 3x - 7[/tex]

[tex]g(x) = 3x + 5[/tex]

[tex]h(x) = 2 {x}^{2} - 4[/tex]

Hence

[tex]f(g(x))[/tex]

[tex] = {(3x + 5)}^{2} + 3 \times (3x + 5) - 7[/tex]

[tex] = (9 {x}^{2} + 30x + 25) + (9x + 15) - 7[/tex]

[tex] = 9 {x}^{2} + 39x + 33[/tex]

[tex]h(g(x))[/tex]

[tex] = 2 \times {(3x + 5)}^{2} - 4[/tex]

[tex]2 \times (9 {x}^{2} + 30x + 25) - 4[/tex]

[tex] = 18 {x}^{2} + 60x + 50 - 4[/tex]

[tex] = 18 {x}^{2} + 60x + 46[/tex]

[tex](h - f)(x)[/tex]

[tex] = h(x) - f(x)[/tex]

[tex] = (2 {x}^{2} - 4) - ( {x}^{2} + 3x - 7)[/tex]

[tex] = {x}^{2} - 3x + 3[/tex]

[tex](f + g)(x)[/tex]

[tex] = f(x) + g(x)[/tex]

[tex] = ( {x}^{2} + 3x - 7) + (3x + 5)[/tex]

[tex] = {x}^{2} + 6x - 2[/tex]

Considering the area of the rectangle, it is found that it's width of the rectangle is of 3 inches.

What is the area of a rectangle?

The area of a rectangle of length l and width w is given by:

A = lw.

In this problem, we have that:

A = 108, l = 6 + 4w.

Hence, using the equation for the area:

lw = 108

(6 + 4w)w = 108

4w² + 6w - 108 = 0

2w² + 3w - 54 = 0

Which is a quadratic equation with coefficients a = 2, b = 3 and c = -54, hence:

[tex]\Delta = b^2 - 4ac = (3)^2 - 4(2)(-54) = 441[/tex]

[tex]x_1 = \frac{-3 + \sqrt{441}}{6} = 3[/tex]

[tex]x_2 = \frac{-3 - \sqrt{441}}{6} = -4[/tex]

Width is a positive measure, hence it is of 3 inches.

Answers

x = tickets used by adults.

Answer:

x=13.9

Step-by-step explanation:

To find x we need an angle other than the right angle to use a trigonometric function. To do this we could either use Sine = Opposite/Hypotenuse or Cosine = Adjacent/Hypotenuse.

In this case i'll be using sine.

To find the angle that is above the right angle we need to use the inverse of Sine. Set up the equation

[tex] \sin^{ - 1} = \frac{22}{26} [/tex]

The answer to this is about 57.8. So now we have an angle to use to solve for x.

So now we set up the proportion

[tex] \frac{ \cos(57.8) }{1} = \frac{x}{26} [/tex]

Cross multiply.

x = 26×cos(57.8)

Put this in a calculator and x is about 13.9

The product of two consecutive positive integers is 812. What is the value of the lesser integer?

Answers

Answer:

It's 28, B

Step-by-step explanation:

EDGE 2022

If product of two consecutive positive integers is 812 then the value of lesser integer is 28.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Let's represent the lesser integer by x.

The next consecutive integer would be x + 1.

According to the problem, the product of these two integers is 812. So we can set up the equation:

x(x + 1) = 812

Expanding the left side and simplifying, we get:

x² + x = 812

Rearranging and factoring the left side, we get:

x² + x - 812 = 0

(x - 28)(x + 29) = 0

we can eliminate the negative value.

Therefore, the value of the lesser integer is 28. option B is correct.

What does x equal?

Answers

Answer:

112

Step-by-step explanation:

So, we know that a triangle's sides must add up to have a sum of 180. If you add up your given lengths and you should get 47, not including x. Then if you look at the left side/the one without a given length and it should be identical to the 21, so you know that side is 21. So now add 21 to 47, you should get 68. Finally, you subtract 68 from 180 like this: 180-68, and it should equal 112. So you're answer is 112.

2x10=20

360–20=34

340/2=170

so, the remaining 3 angles are 10, 170 and 170.

Answer:

10, 170,  170

Step-by-step explanation:

Opposite angles of parallelogram are equal

Consecutive angles in a parallelogram are supplementary (add 180°)

Interior angles in a quadrilateral add up to 360°.

10+10=20   (2 opposite angles of 10 each)

360-20= 340

340/2 = 170 (2 opposite angles of 170)

10+170 = 180 (2 consecitive angles supplementary)

10+10+170+170=360

Answers

The scientific value for n that will make the equation (4.8 × 10^(-3))(n) = 9.6 × 10^9 true is given by: Option D: 2.0 × 10^(12)

How does scientific notations work?

The number is written in the form  [tex]a \times 10^b[/tex]  where we have [tex]1 \leq a < 10[/tex]

The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).

Scientific notations have some of the profits as:

Better readability due to compact representation

Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.

Finding the value of n from the given equation:

[tex](4.5 \times 10^{-3}) \times n = 9.6 \times 10^9\\\\\text{Dividing both the sides by } (4.5 \times 10^{-3}) \\\\n = \dfrac{9.6 \times 10^9}{4.5 \times 10^{-3}} = \dfrac{9.6}{4.5} \times \dfrac{10^{9}}{10^{-3}}\\\\n \approx 2.1333 \times 10^{9-(-3)} = 2.1333 \times 10^{12} \approx 2.0 \times 10^{12}[/tex]

Thus, the scientific value for n that will make the equation (4.8 × 10–3)(n) = 9.6 × 10^9 true is given by: Option D: [tex]2.0 \times 10^{12}[/tex]

let the forth degree of the quadrilateral be y

Then,

Again, the second angle of the triangle be a

Then,

a=111.5(vertically opposite angle)

Lastly,

Giving Brainliest!Read the article Skara Brae:Skara Brae is one of the oldest historical sites in Europe, and it stayed hidden for more than 4,000 years. The ancient village of Skara Brae was discovered on the main island of Orkney, in Scotland. A massive storm in 1850 removed the sand that had covered it for thousands of years, exposing the remains of a small village.Skara Brae is a collection of eight round, stone houses that still have their stone furnishings and even some of the belongings of the inhabitants. The contents can tell us a great deal about how people lived in what is called the Neolithic era, or the last period of the Stone Age. Seven of the eight houses appear to have been family homes, with beds, dressers, fireplaces, and even simple toilets. The eighth house may have been a community workshop. It shows evidence of tool-making and the use of a large fire pit.How was Skara Brae built, and what, eventually, happened to it? Let's journey back in time through the evidence archaeologists have put together to understand the story of Skara Brae.The small, stone village was built sometime around 3100 BCE. The first villagers dug down into an existing midden heap, or trash heap, to build the foundations of their homes. The garbage helped to insulate and protect the homes. They built their round huts with stones found locally, sticking each piece together with a paste made from ground-up waste and dung.After the houses were built, the villagers furnished their homes with stone beds, one on each side of the door, a stone dresser, and a fireplace, or hearth. The hearth kept the home warm and allowed the inhabitants to cook their food.The people of Skara Brae then farmed the surrounding lands, with evidence suggesting that they grew barley and other grains. They kept cows and pigs, and they fished in the ocean for a good part of their diet.As the number of people grew, the village expanded. Covered tunnels and alleyways were built to connect all the homes. This would have protected people traveling from one house to another from cold winter weather. Because of the connections between the houses and the shared workspace, archaeologists believe that Skara Brae was a close-knit community.The people made many things, including pottery, stone tools, and bone jewelry. Curiously, no evidence of weaponry was ever found, leading archaeologists to believe that Skara Brae was a peaceful place.Skara Brae was inhabited for approximately six hundred years, at which point, it was abandoned. Many theories exist about what happened to the people of Skara Brae. One of the most popular theories is that a terrible storm, similar to the one that would uncover the remains of the village in 1850, struck and drove the people from their homes. This is supported by the fact that so many possessions, including valuables like jewelry, were left behind.Which supporting detail supports the main idea that Skara Brae was an ancient village? (A) Because of the connections between the houses and the shared workspace, archaeologists believe that Skara Brae was a close-knit community. (B) Seven of the eight houses appear to have been family homes, with beds, dressers, fireplaces, and even simple toilets. (C) The contents can tell us a great deal about how people lived in what is called the Neolithic era, or the last period of the Stone Age.(d) The first villagers dug down into an existing midden heap, or trash heap, to build the foundations of their homes.Good luck!
