Answer:

D E B C A ⇒ 2nd answer

Step-by-step explanation:

* Lets revise the steps of bisecting a line segment

1. Place the compass at one end of line segment.

2. Open the compass to slightly longer than half the line

    segment length.

3. Draw an arc above and under the line segment

4. Keeping the same compass width, draw an arc above and under

   the line segment from other end of line.

5. Each two arcs intersected at a point over the line and another

   point under the line.

6. Use the ruler to join these point by a line which is the bisector of

   the line segment

* Now lets arrange the steps step

1. Place the compass, and open it wider than half the distance of

   the segment ⇒ D

2. Swing an arc above and below the segment ⇒ E

3. Keeping the compass the same width, Place the compass at

   point B and swing an arc above and below the segment ⇒ B

4. Place points C and D on the intersection of the arcs created

   above and below segment AB ⇒ C

5. Draw a line from point C to point D ⇒ A

∴ The arrange of the statements is ⇒ D E B C A

find the area of a regular pentagon inscribed in a circle whose equation is given by (x-4)^2 + (y+2)^2=25
makkiz [27]
The radius is √25=5 in this case.
find the area of each triangles first. (the pentagon can be divided into 5 isosceles triangles)
the two equal sides are 5 each, the angle between them is 360/5=72 degree, so the base side is 2*5*sin36, and the height is 5*Cos36
the area of each triangle is (1/2)*2*5*Sin36*5*Cos36
the total area of the 5 triangles is: 5*(1/2)*2*5*Sin36*5*Cos36
use a calculator: A≈59.44

I learn maths and I don't know how to solve this problem.
Lyrx [107]

Answer:

As we get closer to x=-3, the limit is approaches -1, on both sides of -3 so this is a good limit so c is 8.

Step-by-step explanation:

In order for a limit to exists, the left side limit must exist and right side limit must exist and on top of that, they must be equal to each other.

In this case, this a piece wise function and by definition of a limit that exist, the limit of this piece wise function as x approaches 3 from either side, must be equal.

We let x=-3 for the top equation.

( - 3) {}^{2}  - 10 =  - 1

So we set the second equation equal to -1.

- ( {x}^{2} ) + c =  - 1

- ( - 3 {}^{2} ) + c =  - 1

- 9 + c =  - 1

c = 8

So the value of c is 8. We can prove this by graphing as well.
