Find the area of the circle:

Diameter: 18 in

Round to the nearest tenth and include units in your answer

Answer:

the answer is d: x=-11/3

Answer:

  B.  -1 ≤ y ≤ 1

Step-by-step explanation:

The range is the vertical extent of the function. Here, it appears the function is a sine function (y=sin(x)). The least value of the function is -1; the greatest value is +1. The function can take on any value between these extremes.

An appropriate description of the range is ...

  -1 ≤ y ≤ 1

Answer:

6.3

Step-by-step explanation:

√6²+2²=√40= 6.3

Answer:

Distance between A and B is approximately 6.3 units

Step-by-step explanation:

We can use the Pythagorean Theorem to solve this question. Notice that the distance in between the two points (straight segment that joins both) can be identified to the "hypotenuse of a right angle triangle shown in the attached image. Such triangle has two legs that measure 2 units one of them and 6 units the other one.

The length of the associated hypotenuse is given then by:

[tex]distance=\sqrt{2^2+6^2}\\distance=\sqrt{40} \\distance=6.32455[/tex]

So this rounded to the nearest tenth is:

6.3 units

Answer:

∠45°

Step-by-step explanation:

When looking at a unit circle, the only acute angle (an angle between

0° and 90°) that consists of an equal sine and cosine is 45°. This is because:

[tex]sin 45 = \frac{\sqrt{2} }{2}[/tex]

[tex]cos45 = \frac{\sqrt{2} }{2}[/tex]

45° is the only acute angle that contains an equal sine and cosine.

Answer:

45 degrees

Step-by-step explanation:

Since Sin(90-x) = Cos(x), we can find that the angle at which 90-x=x is 45 degrees. This corresponds to [tex]\frac{\pi }{4}[/tex] radians

Answer:

Step-by-step explanation:

i think it is a circle

Answer:

Circle

Step-by-step explanation:

The equation for a circle is in the form (x - h)² + (y - v)² = r², where (h, v) is the center of the circle and r is the radius.

A circle with its center at the origin will have an equation that looks like x² + y² = r², which is the form this equation is in.

That's how we know this equation belongs to a circle!

Answer:

You will pay 2550

Step-by-step explanation:

To find the discount, take the  3400 times the 25%

3400 * 25%

850

Subtract this from the original price

3400-850

2550

Answer:

[tex]2550 \: \: \: dollers[/tex]

Step-by-step explanation:

[tex]3400 \times \frac{25}{100} = 850 [/tex]

[tex]3400 - 850 = 2550[/tex]

You have to pay only 2550 dollars.

good luck! have a nice day!

Answer:

Height: 48

Base: 34

Step-by-step explanation:

The formula for a triangle is 1/2(base)(height)

1/2(3x+10)(6x) = 816

18x² + 60x = 1632

18x² + 60x - 1632 = 0

Then, we use the Quadratic formula

x = (-60 ± √3600 + 117,504)/36

x =( -60 ± 348/36)

x = 288/36

x = 8

3(8) + 10

= 34

6(8) = 48

Therefore the dimensions are:

Height: 48

Base: 34

answer:

A) The angles EA and AG are not congruent.

B) m∠F = 90°

m∠E + m∠F = 180°

90 ° + x = 180° (subtract)

x = 90°

C) Both  ∠HEF and  ∠AGF are congruent becuase they both have the same angle.  Try and measure it using a protractor.

Answer:

Third graph down

Step-by-step explanation:

2x -6 ≥ 6(x-2)+8

Distribute

2x - 6≥6x -12+8

Combine like terms

2x - 6≥6x -4

Subtract 2x from each side

2x-6-2x ≥6x-2x-4

-6 ≥4x-12

Add 4 to each side

-6+4 ≥4x-4+4

-2 ≥4x

Divide by 4

-2/4 ≥4x/4

-1/2≥x

Closed circle at -1/2

Answer:

52°

Step-by-step explanation:

By remote interior angle theorem of a triangle:

115° = 63° + x° ( x is the vertical angle of one interior angle of the triangle)

x° = 115° - 63°

x° = 52°

x = 52

Answer:

x = - 2.5

Step-by-step explanation:

Given that the sketch represents

y = x² + bx + c

The graph crosses the y- axis at (0 , - 14), thus c = - 14

y = x² + bx - 14

Given the graph crosses the x- axis at (2, 0), then

0 = 2² + 2b - 14

0 = 4 + 2b - 14 = 2b - 10 ( add 10 to both sides )

10 = 2b ( divide both sides by 2 )

b = 5

y = x² + 5x - 14 ← represents the graph

let y = 0 , then

x² + 5x - 14 = 0 ← in standard form

(x + 7)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x - 2 = 0 ⇒ x = 2

The x- intercepts are x = - 7 and x = 2

The vertex lies on the axis of symmetry which is midway between the x- intercepts, thus

the x- coordinate of the turning point is [tex]\frac{-7+2}{2}[/tex] = [tex]\frac{-5}{2}[/tex] = - 2.5

Answer:

24

Step-by-step explanation:

So basically for every 1 pound of chocolate 3 friends can get 1/3 pounds

now you want to find out how many for 8 pounds

You simply multiply the amount of friends for 1 pound (3) by the total amount he can distribute (8)

you get 24

So the right answer is (7,-2)

Answer:

First answer option:

"The first equation should be multiplied by 2 and the second equation by 3. "

Step-by-step explanation:

The first equation should be multiplied by 2 and the second equation by 3. This way the term in y in the first equation becomes "(2) (-3y) = -6y", and the term in y in the second equation becomes "(3) (2y) = 6y" so when added term by term, the term in "y" disappears.

Answer:

Credit or Cooperative Union

Step-by-step explanation:

Lending institutions can be defined as institutions that provide financial support to people or individuals by making loans available to people who need them.

Lending Institutions can be privately owned and operated or it can be publicly (government) owned and operated. The loans that they make available to people come from the money deposited in such institutions by people or other institutions.

Some types of Lending institutions that we have are:

a) Credit ( Cooperative) Unions

b) Commercial banks

c) Online banks e.t.c.

The type of lending institution that s formed by a group of people who become its members and deposit their money with the institution and can take loans from the institution's available funds is called the CREDIT(COOPERATIVE) UNION.

Answer:

it's either x=75° and y =85°

or x= -75° and y= -85°

because it's below!

Answer:

x=95°

y=105°

Step-by-step explanation:

opposite angle of a cyclic triangle are supplementary.

x+85=180

x=180-85=95°

y+75=180

y=180-75=105°

Answer:

Step-by-step explanation:

Using set notation to answer the question.

let n(U) be the total number of people surveyed = 1000

n(L) be number of people that visited London = 310

n(P) be number of people that visited Paris = 222

n(P∩L) be number of people that visited both cities = 118

n(P∪L)' be number of people that visited none of the cities = x

n(U) = n(PUL) + n(PUL)'

We willl get n(PUL) using the formula;

n(PUL) = n(P)+ n(L)-n(P∩L)

n(PUL)= 222+310-118

n(PUL)= 414

Since n(U) = n(PUL) + n(PUL)'

1000 = 414+n(PUL)'

n(PUL)' = 1000-414

n(PUL)' = 586

586 peoples visitied none of these cities?

Answer:

y+7= -6/5(x+3)

Step-by-step explanation:

Point slope form for a line is given by

y-y1 = m(x-x1) where m is the slope and (x1, y1) is a point on the line

y - -7 = -6/5(x - -3)

y+7= -6/5(x+3)
