Solution :

Given, a circle inscribed in a regular polygon.

From the given different statements,

A. The sides of the polygon are chords of the circle.

B. The sides of the polygon are tangents of the circle.

C. The vertices of the polygon are on the circumference of the circle.

D. The area of the circle is equal to the area of the polygon.

Since, the Circle is inscribed inside the regular polygon, the sides of the polygon must be touching the circle. When we have such an arrangement then those sides must be tangent to the circle. So the sides of the polygon must be a tangent.

Hence, the sides of the polygon are tangents to the circle.

Option B is true and others are false

I'll assume they are. This will give
4(x + 3)(x - 1)
-----------------
(x + 3)(x^2 + 3x)

Th (x + 3) ' s cancel ou so we are left with:_
 4x - 4 
--------
x^2 + 3x

- which is A.

The circumference of the ferris wheel at the county fair is 78.5 feet. what is the diameter in feet? Round to the nearest hundre
-Dominant- [34]
\bf \textit{circumference of a circle}\\\\
C=2\pi r\qquad 
\begin{cases}
diameter=d\\
r=radius=\frac{d}{2}\\
----------\\
C=78.5\\
\end{cases}
\\\\\\
 78.5=2\pi r\implies 78.5=2\pi \cdot \cfrac{d}{2}

solve for "d"

Solve for AB. Round your answer to the nearest tenth if necessary.
NeTakaya

Answer:

See Below

Step-by-step explanation:

You want to find AB.

They give the equation for AB, BC, and AC

AC - BC = AB

substitute the equations

(30) - (8x + 3) = 6x + 8

30 - 8x - 3 = 6x + 8

27 - 8x = 6x + 8

     +8x  +8x

27 = 14x + 8

-8            -8

19 = 14x

19/14 = 14x/14

1.3571428 = x

0.1 = tenth

1.4 = x

Substitute x into the equation for AB

6(1.4) + 8

16.4

The figures are similar. find x. the ratio of the perimeters is 5:7​
anastassius [24]

Answer:

x = 16.8

Step-by-step explanation:

The ratio of corresponding sides is equivalent to the ratio of the perimeters.

Then using proportion

\frac{12}{x} = \frac{5}{7} ( cross- multiply )

5x = 84 ( divide both sides by 5 )

x = 16.8

27. Write down the co-ordinates of the points where the line y = 4x - 3 cuts the x-axis <br>​
Tamiku [17]

Step-by-step explanation:

it is a line, so that is 1 point, where it cuts the x-axis.

in general that means y = 0.

so,

0 = 4x - 3

4x = 3

x = 3/4

the point, where the line cuts the x-axis is

(3/4, 0)
