What is the circumference of a circle whose radius is 20 feet?

9514 1404 393

Answer:

Step-by-step explanation:

Angles opposite congruent sides are congruent, so base angles D and F of this isosceles triangle have the same measure:

  y = 55

__

The sum of angles in the triangle is 180°, so ...

  55° +(11x +4)° +55° = 180°

  11x = 66 . . . . . . . . divide by °, subtract 114

  x = 6 . . . . . . . . . . .divide by 11

The values of x and y are 6 and 55, respectively.

Answer:

Answer:

i wanna say 4.16

Step-by-step explanation:

since the total length is 2.6, going from c to where the point would be if it wasn't reflected but rather transformed would be 2.6, doing that again to get to c" would be 2 times, therefore I think it's 4.16

Equation of circle G: [tex]\bold{(x-3)^{2} + (y-4)^{2} = 49}[/tex]

"An equation of a circle with center (p, q) and radius r is:[tex](x-p)^{2}+ (y-q)^{2}=r^{2}[/tex] "

"The coordinates of the midpoint M of two points (a, b) and (x, y) :

[tex]M(\frac{a+x}{2} ,\frac{b+y}{2} )[/tex] "

"The distance between two coordinate points (a, b), (m, n):

[tex]d=\sqrt{(n-b)^{2} +(m-a)^{2} }[/tex] "

"A diameter of a circle is the straight line that from one side of a circle to other side and passes through the center."

For given question,

The line segment connecting the two points B(-4,4) and D (10,4) is a diameter of the circle.

This means, the midpoint of the diameter BD would be the center of a circle G.

Let M represents the center of the circle.

First we find the coordinates of the center of the circle.

Using midpoint formula,

⇒ M = [tex](\frac{-4+10}{2} ,\frac{4+4}{2} )[/tex]

⇒ M = (6/2 , 8/2)

⇒ M = [tex](3,4)[/tex]

Now, we find the distance between points B(-4,4) and D (10,4) to determine the diameter of a circle G.

Using distance formula,

⇒ [tex]d=\sqrt{(4-4)^{2} +(10-(-4))^{2} }[/tex]

⇒ [tex]d=\sqrt{0+(14)^{2} }[/tex]

⇒ [tex]d=14[/tex] units

So, the radius of the circle r would be,

r = d/2

⇒ r = 14 / 2

⇒ r = 7 units

Now, we find the equation of circle with center M(3, 4) and radius r = 7 units.

Using center - radius form equation of circle would be,

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

⇒ [tex]\bold{(x-3)^{2} + (y-4)^{2} = 49}[/tex]

Therefore, option (A) is the correct answer.

Answer:

This is a difficult question

Step-by-step explanation:

is it 3 part?

Answer:

C

Step-by-step explanation:

the range is all the possible numbers on the Y axis. We can see that the graphs peaks at 3 and then goes down both ways. This means that eventually the y axis will be equal to all real numbers less than 3

The range of the function looks to be all real numbers less than or equal to -1, according to the provided graph. The best choice is B.

This is due to the fact that the graph's horizontal line at y=-1, which shows that the function accepts all values less than or equal to -1, stretches eternally in both directions.

The collection of all potential output values that a function can take on is generally referred to as the function's range. You can look at the vertical spread of the graph to see what values the function can take on in order to determine the range of a function from its graph.

Observe that the accompanying graph features a horizontal line at y=-1 that spreads out infinity in both directions. This indicates that for all values of x, the function takes on the value of -1.

The graph also features a vertical line at x=2 that goes on forever in both directions, as can be seen. This shows that the function can accept any value of y for x=2.

Combining these findings, we can determine that the function has a range of all real numbers less than or equal to -1 since it takes on the value of -1 for all x and the range of potential values of y is unrestricted.

Step-by-step explanation: First change the minus inside to plus a negative.

Now we can distribute the -8 through each

of the terms inside the set of parenthses.

So we have -8(2y) + -8(-3) or -16y + 24.

Take a look below.

Answer:

-20=-20

Step-by-step explanation:

Distribute the 4.

(4xp-20)-8=4p-28

get rid of the variables (replace p with 2)

(8-20)-8=8-28

Simplify or combine like terms

-12-8=-20

Simplify or combine like terms

The solutions from least to greatest are lesser x = -2 and greater x = 2/3 for the equation (2x +4)(3x -2)=0

An equation is collection of two or more expressions with an Equal sign

The given equation is (2x +4)(3x -2)=0

To find the solutions, we set each factor equal to zero and solve for x

2x + 4 = 0

Subtract 4 from both sides

2x = -4

Divide both sides by 2

x = -2

Now 3x - 2 = 0

Add 2 on both sides

3x = 2

Divide both sides by 3

x = 2/3

Therefore, the solutions from least to greatest are lesser x = -2 and greater x = 2/3

Answer: n is greater than or equals to 1, where n is an integer

Step-by-step explanation:

The domain Abraham should use for s so it generates the sequence is n ≥ 1 where n is an integer option (C) is correct.

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

Abraham is writing a recursive function for the geometric sequence:

24, 12, 6,3,

The above sequence is a geometric progression.

The first term geometric progression is 24

s(1) = 24

s(n) = s(n-1)(1/2)

The nth term of the geometric progression:

The common ratio = 12/24 = 1/2

s(n) = s(n-1)(1/2)

Here n should be an integer number that is greater than 1

n ≥ 1 where n is an integer.

Thus, the domain Abraham should use for s so it generates the sequence is n ≥ 1 where n is an integer option (C) is correct.
