Plz help.<br><br> Find the perimeter of the window to the nearest tenth.
Stels [109]
Let's solve this problem step-by-step.

STEP-BY-STEP EXPLANATION:

First, we will establish that the shape of the window is a semi-circle. This means we must use the formula for the perimeter of a semi-circle to obtain the perimeter of the window.

The formula for the perimeter of a semi-circle is as follows:

Let perimeter of window or semi-circle = P

P = [ 2( Pi )r / 2 ] + 2r

Where r = radius of circle or semi-circle

From this, we will simply use the value of the radius given from the diagram in the problem and substitute it into the formula to obtain the perimeter of the window.

P = [ 2( Pi )r / 2 ] + 2r

r = 20

THEREFORE:

P = [ 2( Pi )( 20 ) / 2 ] + 2( 20 )

P = 20( Pi ) + 40

P = 102.83...cm^2

P = 102.8cm^2 ( to the nearest tenth )

FINAL ANSWER:

Therefore, the perimeter of the window is 102.8cm^2 ( to the nearest tenth ).

Hope this helps! :)

Write a series of rigid motions that transform pentagon ABCDE to pentagon A′B′C′D′E′
worty [1.4K]

Answer:

We need the following three rigid motions:

i) Reflection around y-axis, ii) Translation three units in the -y direction, iii) Translation four units in the -x direction.

Step-by-step explanation:

We need to perform three operations on pentagon ABCDE to create pentagon A'B'C'D'E':

i) Reflection around y-axis:

(x',y') = (-x,y) (Eq. 1)

ii) Translation three units in the -y direction:

(x'',y'') = (x', y'-3) (Eq. 2)

iii) Translation four units in the -x direction:

(x''',y''') = (x''-4, y'') (Eq. 3)

We proceed to proof the effectiveness of operations defined above by testing point D:

1) D(x,y) = (-1, 4) Given.

2) (x',y') = (1,4) By (Eq. 1)

3) (x'',y'') = (1, 1) By (Eq. 2)

4) D'(x,y) = (-3,1) By (Eq. 3)/Result

Use the figure below to Find midsegment please help
serious [3.7K]

Answer:

38 units.

Step-by-step explanation:

4x + 6 = \frac{1}{2}(4x + 44)      {midpoint theorem}

4x + 6 = \frac{1}{2}*4x +  \frac{1}{2}*44

4x + 6 = 2x + 22

4x -2x + 6 = 22

  2x   + 6  = 22

           2x = 22 -6

          2x = 16

            x = 16/2

            x = 8

Length of midsegment = 4x + 6 = 4*8 + 6

                                     = 32 + 6

                                     = 38
