Answer:

The Circumference is 150.7 inches

Step-by-step explanation:

The cricumference of a circle is given by the formula:

[tex]C = 2\pi r[/tex]

We are given the radius and are given 3.14 for pi.

Substituting these values into the euation gives us:

C = 2(3.14)(24)

C = (6.28)×(24) = 150.72

The Circumference is 150.7 inches to the nearest tenth.

Step-by-step explanation:

1.

the indicated point in the middle is the center point of the circle.

the line perpendicular to a chord going through that center solid the chord in half.

so,

x = 9

2.

Pythagoras

c² = a² + b²

13.5² = x² + 10.4²

182.25 = x² + 108.16

x² = 74.09

x = 8.607554821...

3.

Intersecting Chords Theorem

(part one of chord 1)×(part two of chord 1) =

= (part one of chord 2)×(part two of chord 2)

6x = 10×9 = 90

x = 90/6 = 30/2 = 15

4.

Intersecting Chords Theorem again

x(x+3) = 4×10 = 40

x² + 3x = 40

x² + 3x - 40 = 0

generation solution to a quadratic equation

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 3

c = -40

x = (-3 ± sqrt(3² - 4×1×-40))/(2×1) =

= (-3 ± sqrt(9 + 160))/2 = (-3 ± sqrt(169))/2 =

= (-3 ± 13)/2

x1 = (-3 + 13)/2 = 10/2 = 5

x2 = (-3 - 13)/2 = -16/2 = -8

negative values for a length do not make sense, so x = 5 is our solution

5.

Intersecting Chords Theorem

(x+1)×4 = (x-1)×5

4x + 4 = 5x - 5

9 = x

Answer: y + [tex]\frac{12}{7}[/tex]x = -[tex]\frac{16}{7}[/tex]

Step-by-step explanation:

    Standard form is Ay + Bx = C,

Given:

y+4=-12/7(x-1)

Rewrite:

y + 4 = [tex]\frac{-12}{7}[/tex](x - 1)

Distribute:

y + 4 = [tex]\frac{-12}{7}[/tex]x  + [tex]\frac{12}{7}[/tex]

Subtract 4 from both sides:

y =  [tex]\frac{-12}{7}[/tex]x  + [tex]\frac{12}{7}[/tex] - 4

Add  [tex]\frac{12}{7}[/tex]x to both sides:

y + [tex]\frac{12}{7}[/tex]x = + [tex]\frac{12}{7}[/tex] - 4

Combine like terms:

y + [tex]\frac{12}{7}[/tex]x = -[tex]\frac{16}{7}[/tex]

Answer:

  10 units wide; 24 units long

Step-by-step explanation:

The width is represented by the variable w in the given equation ...

  w(2w +4) = 240

__

This is conveniently divided by 2. Writing in standard form lets us see potential factoring.

  w(w +2) = 120

  w² +2w -120 = 0

  (w +12)(w -10) = 0 . . . . . . factor

  w = -12  or  w = 10 . . . . . width

  2w+4 = 2(10) +4 = 24 . . . length

The positive solution to this equation is the one of interest here.

The width of the rectangle is 10 units; its length is 24 units.

[tex]s(w) = 15w[/tex]

To create the composite function, replace the variable [tex]s[/tex] in the function f(s) with function s(w):

Took it on edge 2022

Step-by-step explanation:

there is one central rectangle :

from (-4, 2) to (2, -2).

that means it dimensions are 6×4 (for x from -4 to +3, for y from +2 to -2).

and then there are 3 additional triangles

(2, -4) (2, 2) (6, 2)

(-4, -2) (2, -2) (2, -4)

(-6, 2) (-4, 2) (-4, -2)

with the leg lengths

(2, -4) to (2, 2) = 6, and (2, 2) to (6, 2) = 4

(-4, -2) to (2, -2) = 6, and (2, -2) to 2, -4) = 2

(-6, 2) to (-4, 2) = 2, and (-4, 2) to (-4, -2) = 4

the area of the rectangle is

6×4 = 24 square units

the area of the first triangle is

6×4/2 = 3×4 = 12 square units

the area of the second triangle is

6×2/2 = 6 square units

the area of the third triangle is

2×4 = 8 square units.

so, the total area is

24 + 12 + 6 + 8 = 50 square units.

Step-by-step explanation:

The correct steps to transform x² + 10x + 24 = 0 into the form (x − p)² = q is

d.

Step 1: x² + 10x + 24 + 1 = 0 + 1

Step 2: x² + 10x + 25 = 1

Step 3: (x + 5)² = 1

To transform x² + 10x + 24 = 0 into the form (x − p)² = q where [p and q are integers], we perform the following steps of transformation.

This is process of converting one expression to the other by performing some mathematical operations.

x² + 10x + 24 = 0

We add 1 to both sides.So,

Step 1: x² + 10x + 24 + 1 = 0 + 1

Thus, we have

Step 2: x² + 10x + 25 = 1

Since the left-hand-side x² + 10x + 25 = (x + 5)²

So, we have

x² + 10x + 25 = 1

Step 3: (x + 5)² = 1

So, the correct steps to transform x² + 10x + 24 = 0 into the form (x − p)² = q is

d.

Step 1: x² + 10x + 24 + 1 = 0 + 1

Answer:

1/12

Step-by-step explanation:

The probality of getting a 3 on a die is ⅙ since they is only one 3 on the 6 sided die. So that will mean there is a 1 in 6 chance to get a 3.

Then the probability of getting tails on a coin is ½ because a coin on has 2 sides.

The probability of getting the 3 on the die and a tail on a coin will be the probability of getting the 3 on the die times the probability of getting the tails on the coin.

⅙×½=1/12

PQ is the diameter so the midpoint of PQ is the center of the circle. if we suppose the center point of the circle called o then ;

[tex]o = \frac{pq}{2} \\ [/tex]

[tex]pq = \sqrt{ { (- 10 - 6})^{2} + ({10 - ( - 2)})^{2} } [/tex]

[tex]o = \frac{( -10 ,10) + (6 , - 2) }{2} \\ [/tex]

[tex]o = \frac{( - 10 +6 ,10 - 2)}{2} \\ [/tex]

[tex]o = ( \frac{ - 4}{2} , \frac{8}{2} ) \\ [/tex]

[tex]o = ( - 2,4)[/tex]

For the second step we need to find the radius of the circle which has the half the PQ distance measure, so we have to find the the PQ distance and divide it by 2 :

_____________________________________________

As u know the distance between 2 point is going to find by following formula :

[tex]pq = \sqrt{ {(x(p) - x(q)})^{2} + {(y(p) - y(q)})^{2} } \\ [/tex]

[tex]pq = \sqrt{ ({ - 10 - 6})^{2} + ({10 - ( - 2)})^{2} } [/tex]

[tex]pq = \sqrt{ ({ - 16})^{2} + ({12})^{2} } [/tex]

[tex]pq = \sqrt{256 + 144} [/tex]

[tex]pq = \sqrt{400} [/tex]

[tex]pq = 20[/tex]

Thus :

[tex]radius = \frac{pq}{2} \\ [/tex]

[tex]radius = \frac{20}{2} \\ [/tex]

[tex]radius = 10[/tex]

Ok we're almost done cuz we have what we needed:

Is the equation of the circle in the standar form thus :

[tex] ({x - ( - 2)})^{2} + ({y - 4})^{2} = {10}^{2} \\ [/tex]

[tex] ({x + 2})^{2} + ({y - 4})^{2} = 100[/tex]
