A sector of a circle has a central angle measuring 15 degrees and the radius of the circle measures 9 inches. What is the arc le

Kamila [148]

Answer:

Arc length is $\dfrac{3\pi }{4}\ \text{inches}$

Step-by-step explanation:

We have,

Central angle is 15 degrees and the radius of the circle measures 9 inches.

It is required to find the arc length of the sector.

The relation between arc length and the central angle is given by :

$\dfrac{\text{arc length}}{\text{circumference}}=\dfrac{\theta}{360}$

Circumference, $C=2\pi r=18\pi$

$\theta=15^{\circ}$

$\dfrac{x}{18\pi }=\dfrac{15}{360}\\\\\dfrac{x}{18\pi }=\dfrac{1}{24}\\\\x=\dfrac{18\pi }{24}\\\\x=\dfrac{3\pi }{4}\ \text{inches}$

Hence, the correct option is (b).

Which expression is equivalent to sqrt128x^5y^6/2x^7y^5 ? Assume x 0 and y > 0.

kolbaska11 [484]

Answer:

$\frac{8\sqrt{y} }{x}$

Step-by-step explanation:

We are given the following expression and we are to simplify it:

$\sqrt {\frac {128x^5y^6} {2x^7y^5} }$

To make it easier to solve, we can also write this expression as:

$\sqrt {\frac{128}{2} * \frac {x^5} {x^7} * \frac {y^6} {y^5}}$

Now we will cancel out the like terms to get:

$\sqrt {64*\frac{1} {x^2}*y }$

Taking the square root of the terms to get:

$8*\frac {1}{x} .\sqrt{y}$

$\frac{8\sqrt{y} }{x}$

Victoria holds a 5 foot long fishing pole. The fishing line extends 3 feet to the water's surface and then another 12.6 feet to

nevsk [136]

The fish, the fishing pole and the water surface are all in equivalent ratio, and the fish is 21 feet from the hook

<h3>How to determine the distance between the fish and the hook?</h3>

To do this, we make use of the following equivalent ratio

3 : 12.6 = 5 : x

Where x represents the distance between the fish and the hook

Express the ratio as a fraction

12.6/3 = x/5

Multiply both sides by 5

x = 5 * 12.6/3

Evaluate

x = 21

Hence, the fish is 21 feet from the hook
