Answer: Option C

AC = 2\pi

Step-by-step explanation:

The arc length is calculated as

L = \theta * R

Then

AC = \theta * R

We know that

BC = 24\ ft

If BC is the diameter of the circumference then the radius R is:

R = \frac{BC}{2}

R = \frac{24}{2}

R = 12\ ft

Now we convert the anglo from degrees to radians\theta= 30\° * \frac{\pi}{180\°}\\\\\theta=\frac{1}{6}\pi

Finally

AC = \frac{1}{6}\pi * 12

AC = 2\pi

Answer:

The length of the arc AC is 2π ⇒ answer C

Step-by-step explanation:

* Lets revise some facts in the circle

- The length of the arc is depends on the measure of the arc and the

  radius of the circle

- The length of the arc is a part of the length of the circle

- The length of the circle is 2πr

- The rule of the length of the arc = \frac{\alpha }{360}*2\pi r,

  where α is the measure of the arc

* Now lets solve the problem

- In circle P

∵ BC is a diameter

∵ BC = 24 ft

∵ The length of the radius of the circle is 1/2 the length of the diameter

∴ The length of the radius = 1/2 × 24 = 12 ft

- Ac is an arc in the circle

∵ The measure of the arc = 30°

∵ The length of the arc = \frac{\alpha }{360}*2\pi r ,

  where α is the measure of the arc

∴ α = 30°

∵ r = 12 ft

∴ The length of the arc = \frac{30}{360}*2(12)\pi=\frac{1}{12}*(24)\pi=2\pi

∴ The length of the arc AC is 2π

Solve the equation. Check your solution.<br> 3x+4x-8=6<br> x= <br> ​(Simplify your​ answer.)
KengaRu [80]

Answer:

<h2>x=2</h2>

Step-by-step explanation:

Isolate x

3x + 4x - 8 = 6

             +8    +8

3x + 4x = 6 + 8

Simplify

3x + 4x = 6 + 8

7x = 14

Divide both sides by 7

7x/7 = 14/7

x = 2

F (x) =2x -4; find f (-4)
NemiM [27]

Answer:

f(-4) = -12

Step-by-step explanation:

f(x)=2x-4

To calculate f(-4), we need to substitute x in our equation above with -4:

f(x)=2x-4\\f(-4) = 2*(-4) - 4\\f(-4) = -8-4 = -12

Note that 2*(-4) = -8

Answer: f(-4) = -12

Write <br>(6b)^2 without exponents
Nikolay [14]
Squaring a number means you're multiplying the number by itself. This would mean (6b)^2 = (6b)(6b).
