If YV = 28 in, find the length of the major arc VYX. Round to the nearest tenth ( one decimal place).

denpristay [2]

Answer:

$VYX=84.3in$

Step-by-step explanation:

Given

$YV = 28in$

$\angle WZX = 15^\circ$

See attachment

Required

Determine the length of $VYX$

First, calculate the major angle VZX

$\theta = \angle VZX = 360 - \angle WZX$

$\theta = \angle VZX = 360 - 15$

$\theta = \angle VZX = 345$

$\theta = 345$

The length of arc VYX, is:

$L=\frac{\theta}{360} * 2\pi r$

Where

$r = \frac{1}{2} * Diameter$

$r = \frac{1}{2} * YV$

$r = \frac{1}{2} * 28$

$r = 14$

So:

$L=\frac{\theta}{360} * 2\pi r$

$L=\frac{345}{360} * 2 * \frac{22}{7} *14$

$L=\frac{345}{360} * 2 * 22 *2$

$L=\frac{345* 2 * 22 *2}{360}$

$L=\frac{30360}{360}$

$L=84.3in$

Hence, the length of VYX is:

$VYX=84.3in$

What is the slope of the line that passes through the points: (3, -4) & (9, 0)?

ivolga24 [154]

Answer: the slope is 2/3.

Step-by-step explanation: The expression for finding slope when given 2 coordinates of the line is (y2 - y1) ÷ (x2 - x1) which just means that you take the y output of the second coordinate given to you and subtract the y output of the first coordinate given from that and the same for the x inputs. So when you plug in the numbers into that expression, you get (0- (-4)) ÷ (9 - 3). When you subract something from a negative number, its the same as adding. So it could also be written as (0 + 4) ÷ (9 - 3). When you subtract and add the numbers in both parentheses you end up with the fraction 4/6, but now you need to simplify that fraction which leaves you with the final answer of the fraction 2/3!

I hope this helps :)
