Help down below pleaseee. I'll rlly give brainliest whoever gives me the best answer if it allows me too since I need at least 2 ppl answering.

Answer:

9 pi

Step-by-step explanation:

First find the circumference of the circle

C =2 * pi *r

C = 2 * pi *9

C = 18 pi

This is a semicircle which is 1/2 of a circle

Take 1/2 of the circumference

1/2 C = 1/2 ( 18 pi)

1/2 C = 9 pi

Given,

[tex]3x - 2y = 5[/tex]

[tex]xy = - 2[/tex]

Now,

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

Use the algebraic identity ⇻ (a - b)² = a² - 2ab + b²

[tex](3x - 2y) {}^{2} = (5) {}^{2} \\ 3x {}^{2} - 2 \times 3x \times 2y + 2y {}^{2} = 5 {}^{2} \\ 9 {x}^{2} - 12xy + 4y {}^{2} = 25 \\9x {}^{2} + 4y {}^{2} = 25 + 12xy \\ 9x {}^{2} + 4 {y}^{2} - 1 = 24 + 12xy[/tex]

✐ So, the value of 9x² + 4y² - 1 is 24 + 12xy

Now,

xy = - 2

So, 12xy = 12 × - 2 = - 24

•°• 24 + 12xy

= 24 + (-24)

= 24 - 24

= 0

Step-by-step explanation:

its the only  one on the line

runner C is tall like a mountan

and runner A is not anywhere close to a line

Answer:

D is the answer

hope this helps

have a good day :)

Step-by-step explanation:

Answer:

29 = c

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2+b^2= c^2  where a and b are the legs and c is the hypotenuse

20^2 + 21^2 = c^2

400 +441 =c^2

841 = c^2

Take the square root of each side

sqrt(841) = sqrt(c^2)

29 = c

Answer:

c = 29 km

Step-by-step explanation:

21² + 20² = c²

441 + 400 = 841

√841 = 29

Answer:

1. translation down and to the right

2. reflection over y-axis

3. rotation

Answer:

(0,-4) and (2,0)

Step-by-step explanation:

you cut off the screen shot, so not all answer options are visible.

but from the graph we can pretty reliably deduct, that the solutions (the crossing points of both functions) are

(0,-4) and (2,0)

Answer:

24 codes are possible

Step-by-step explanation:

0 through 4 means we are to select from 0,1, 2 , and 4

That’s a total of 4

The first number has 4 choices, the second 3, the 3rd two and the last 1

The product of the choices are;

4 * 3 * 2 * 1 = 24 codes

Answer:

  (a)  (5π -11.6) ft²

Step-by-step explanation:

The shaded area is the area of 1/5 of the circle less the area of the triangle with base 5.8 ft and height 4 ft.

  shaded area = 1/5(π(5 ft)²) -(1/2)(5.8 ft)(4 ft)

  shaded area = (5π -11.6) ft²

Answer:

You are correct.

Step-by-step explanation:

Probably too late, but 475 x 3 = 1425. Since it is a loss, the negative sign is appropriate.

Answer:

NO

Step-by-step explanation:

Triangle A suggests that the triangle is isosceles.

Isosceles:

Triangle with two congruent angles and sides:

7 , 6 , 7

5 , 4 , 5

9, 12 , 9

Triangle B suggests that the triangle is scalene.

Scalene:

Triangle with no congruent angles or sides:

5 , 6 , 7

10 , 15 , 7

12 , 18 , 21

Answer:

y = -7

Step-by-step explanation:

The line represents the y-coordinate, because it is a straight line over the x axis, indicating it cant be an x coordinate

Because it is 7 units below the x-axis, it is -7

y = -7

Step-by-step explanation:

Answer:

-11/4

(I think you meant -3/2 not -2/3 at the end there.)

Step-by-step explanation:

If it is arithmetic, it's going up or down by same number.

So we started with 7/2 and went down to 9/4.

If we can find how much it went down, then we can find the next term after -3/2.

Find difference

7/2-9/4

Find common denominator

14/4-9/4

5/4

So we are going down by 5/4 each time.

That means the following equations should ve true:

7/2-5/4=9/4

9/4-5/4=1

1-5/4=-1/4

-1/4-5/4=-3/2

And all of these are in fact true.

The next term in the sequence will be

-3/2-5/4.

Find common denominator

-6/4-5/4

-11/4

Answer:

1.3675374e+12

Step-by-step explanation:

that's what the calculator said

v = u + 5t

v = -15 + 5(4)

v = -15 + 20

v = 5

Answer:

[tex]\huge\boxed{Answer\hookleftarrow}[/tex]

[tex]v = u + 5t[/tex]

Given,

[tex]u = - 15 \\ t = 4 \\ v = \: ?[/tex]

To find the value of v, we must substitute the values of u & t in the equation ⇻ v = u + 5t.

[tex]v = u + 5t \\ v = ( - 15) + 5(4) \\ v = - 15 + 20 \\ v = 5[/tex]

✐ The value of v is 5.

Answer:

6 x 4 = 24, 24 x 2 = 48

7 x 6 = 42

7 x 4 = 28, 28 x 2 = 56

6 x 4 x 1/2(basically just dividing by 2) = 12, 12 x 2(two triangles) = 24

5 x 5 = 25, 25 x 2 = 50

Add given areas:

48 + 42 + 56 + 24 + 50 = 220 ft^2 is your answer.

Problem 3

-------------------------

Explanation:

Two points from the graph are (10,2) and (20,4)

Apply the slope formula

m = (y2-y1)/(x2-x1)

m = (4-2)/(20-10)

m = 2/10

m = 1/5

The slope of the graph is 1/5.

Do the same for two points from the table. I'll use the first two rows

m = (y2-y1)/(x2-x1)

m = (4-2)/(10-5)

m = 2/5

The slope of the table is 2/5.

Subtract the two slopes to wrap things up:

2/5 - 1/5 = (2-1)/5 = 1/5

=====================================================

Problem 5

------------------------

Explanation:

Angles 1 and 3 are same side exterior angles, so they are supplementary due to the parallel lines set up here.

(angle1)+(angle3) = 180

(157) + (angle3) = 180

angle3 = 180-157

angle3 = 23 degrees

Answer:

Lily spent $19.20, Sue spent $4.80. Make sure to include the units.

Step by Step:

Lets say Sue is X

4x+x=24

5x=24

x=24/5

x=4.8

So sue spent 4.8.

24-4.8=19.2

Lily spent 19.2

Check:  4(4.8)=19.2

19.2+4.8=24
