The regular octagon has a perimeter of 122.4 cm. Which statements about the octagon are true? Check all that apply.

Papessa [141]

Answer:

The length of segment XY can be found by solving for a in

$20^2-7.65^2=a^2$

The measure of the central angle $\angle ZXW$ is $45\degree$ .

Step-by-step explanation:

If the regular octagon has a perimeter of 122.4cm, then each side is $\frac{122.4}{8}=15.3cm$

The measure of each central angle is $\frac{360\degree}{8}=45\degree$

The angle between the apothem and the radius is $\frac{45}{2}=22.5\degree$

The segment XY=a is the height of the right isosceles triangle.

We can use the Pythagoras Theorem with right triangle XYZ to get:

$a^2+7.65^2=20^2$

$a^2=20^2-7.65^2$

Therefore, the correct options are:

The length of segment XY can be found by solving for a in

$20^2-7.65^2=a^2$

The measure of the central angle $\angle ZXW$ is $45\degree$ .

Take a factor out of the square root:

Andrews [41]

Answer:

1. |y| sqrt(10)

2. |x| sqrt(x)

3. a^2 sqrt(a)

4. 4 |y|^3 sqrt(3)

5. 1/4 *|x| sqrt(3x)

Step-by-step explanation:

1. sqrt(10y^2)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(y^2) sqrt(10)

|y| sqrt(10)

We take the absolute value of y because -y*-y = y^2 and the principle square root is y

2. sqrt(x^3)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(x^2) sqrt(x)

|x| sqrt(x)

3. sqrt(a^5)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(a^4) sqrt(a)

a^2 sqrt(a)

4. sqrt(16 y^7)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(16) sqrt(y^6)sqrt(y)

4 |y|^3 sqrt(3)

5. sqrt(3/16x^3)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(1/16) sqrt(x^2)sqrt(3x)

1/4 *|x| sqrt(3x)

I NEED HELP ASAP

Maru [420]

Answer:

1x + 4y = 4 ⇒ 6x + 24y = 24

6x - 8y = 0 ⇒ 6x - 8y = 0

32y = 24

32 32

y = 3/4

x + 4(3/4) = 4

x + 3 = 4

-3 -3

x = 1

(x, y) = (1, 3/4)
