Second option is correct

$Arc\ length = \frac{3}{4} \pi\ in$

Step-by-step explanation:

Given:

Central angle = 15°

Radius of the circle = 9 in

Arc length = ?

Given formula is

$\frac{Arc\ length}{Circumfrance} = \frac{n}{360}$

Where n is the central angle of the sector.

Write the given formula for Arc length of the sector.

$Arc\ length = Circumfrance\times \frac{n}{360}$

We know that the the circumference of the circle is $2\pi r$ , where r is the radius of the circle,

$Arc\ length = 2\pi r\times \frac{n}{360}$

Now we substitute central angle value and radius value in above equation.

$Arc\ length = 2\pi 9\times \frac{15}{360}$

$Arc\ length = 18\times \pi \frac{15}{360}$

$Arc\ length = \frac{18\times 15}{360} \pi$ ----------( $\frac{18}{360}=\frac{1}{20}$ )

$Arc\ length = \frac{15}{20} \pi$

Divide the numerator and denominator by 5.

$Arc\ length = \frac{3}{4} \pi\ in$

Therefore the arc length of the sector is $\frac{3}{4} \pi\ in$

Select the correct answer. What is the completely factored form of this polynomial? 2x5 + 12x3 − 54x A. 2x(x2 + 3)(x + 9)(x − 9)

Answer:

Step-by-step explanation:

2x(x^4 + 6x^2 - 27)

x^4 + 6x^2 - 27 = 0

x^2 = y

y^2+ 6y - 27 = 0

(y+9)(y-3) = 0

(x^2+9)(x^2-3) = 0

2x(x^2-3)(x^2+9)

For the graph y = 4 find the slope of a line that is perpendicular to it.

The perpendicular line would be vertical and therefore undefined.
