Consider a regular hexagon inscribed in circle C with radius r. Regular hexagons have six congruent sides and six congruent angl
Leokris [45]

The solution to the questions are:

  • The value of < ACB\ is\ 60\textdegree. As a consequence, the radius of the circle is equal to the length of the segment AB.

  • AB = BC =CA = R. As a consequence, the radius of the circle is equal to the length of the segment AB.  

  • The perimeter of the hexagon is equal to r times 6. As a result, the number 6r represents the hexagon's perimeter.

  • P=6.28r. As a result, the diameter of the circle is a fraction of a unit bigger than.

  • P=6.28r. As a result, the diameter of the circle is a fraction of a unit bigger than.

<h3>What is the length of segment AB?</h3>

1) Generally, the equation for  m∠ACB is  mathematically given as

CA= CB

CA = radius of the circle

Therefore,

∠CAB =

\angle CBA = 60 \textdegree

the sum of all the angles of a triangle

the sum of all the angles of a triangle is 180°

< CAB + < CBA + < ACB = 180 \textdegree

60\textdegree + 60\textdegree + < ACB = 180\textdegree

120\tetxtdegree + < ACB = 180\tetxtdegree

< ACB = 60\textdegree

The value of < ACB\ is\ 60\textdegree.

2. What is the length of segment AB?

In the same manner, as in ACB, all of the angles are the same. As a result, we may say that the triangle has equal sides.

In a triangle with equilateral sides, each of the triangle's three sides has the same length.

AB = BC =CA = R

As a consequence, the radius of the circle is equal to the length of the segment AB.

<h3>3. What is the perimeter of the hexagon?</h3>

The formula for calculating the hexagon's perimeter is 6a, where an is the number of sides in the hexagon.

The circumference of the hexagon is equal to 6 times a.

The circumference of the hexagon is equal to six times each side (AB)

The perimeter of the hexagon is equal to r times 6.

As a result, the number 6r represents the hexagon's perimeter.

4. The perimeter of the hexagon is  6r the circumference of the circle.

  • the perimeter of the hexagon = 6r
  • the perimeter of the circle = 2 \pi

P=2*\pi*r

P=2*3.14*r

P=6.28r

As a consequence of this, the hexagon's perimeter is less than the diameter of the circle.      

5. The circumference of the circle is 6.28r.

the perimeter of the circle = 2 \pi r

P=2*\pi*r

P=2*3.14*r

P=6.28r

As a result, the diameter of the circle is a fraction of a unit bigger than.

Nancy walks 5 blocks to the right, 3 blocks down, 7 blocks to the left, and 1 block up. Each square's side length is 1 block. Wh
NeTakaya

Answer:

The coordinates of her new position are (0 , -5) ⇒ answer B

Step-by-step explanation:

* Lets revise some translation

- If the point (x , y) translated horizontally to the right by h units

 then the new point = (x + h , y)

- If the point (x , y) translated horizontally to the left by h units

 then the new point = (x - h , y)

- If the point (x , y) translated vertically up by k units

 then the new point = (x , y + k)

- If the point (x , y) translated vertically down by k units

 then the new point = (x , y - k)

* Now lets solve the problem

∵ Nancy start from position (2 , -3)

- She walks 5 blocks to the right and 3 blocks down

∴ Add x-coordinate by 5 and subtract y-coordinate by 3

∵ The starting position is (2 , -3)

∴ The new position is (2 + 5 , -3 - 3) = (7 , -6)

- She walks 7 blocks to the left and 1 block up

∴ Subtract x-coordinate by 7 and add the y-coordinate by 1

∴ The new position is (7 - 7 , -6 + 1) = (0 , -5)

* The coordinates of her new position are (0 , -5)

Write an equation in slope intercept: 6x+5y=30
KATRIN_1 [288]
The equation for slope-intercept form is y = mx + b; "m" representing the slope and "b" representing the y-intercept. Let's set this equation to where the "y" variable is by itself and in slope-intercept form.
5y = 6x + 30
This is the correct equation for slope-intercept form.

I hope this helps!
