I don't know because I can't understand English language
Answer:
8
Step-by-step explanation:
since the y values are the same in each point, we know the distance is a straight, and is equal to the distance between the x values.
we know that the second point is 5 units right of 0, and is 3 units left of 0.
5 + 3 = 8
Answer:
Step-by-step explanation:
Arc length of a circle is given by,
Arc length = ![\frac{\theta}{360}(2\pi r)](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctheta%7D%7B360%7D%282%5Cpi%20r%29)
Here, θ = Central angle subtended by the arc
r = Radius of the circle
From the given picture,
θ = 45°
r = 1 unit
Therefore, arc length = ![\frac{45}{360}(2\pi r)](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B360%7D%282%5Cpi%20r%29)
= ![\frac{1}{8}(2\pi r)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7D%282%5Cpi%20r%29)
= ![\frac{2\pi }{8}(r)](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%20%7D%7B8%7D%28r%29)
= ![\frac{\pi}{4}(r)](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%7D%7B4%7D%28r%29)
Arc length =
units
=
units
Angle θ has a measure = ![\frac{45}{360}\times \pi](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B360%7D%5Ctimes%20%5Cpi)
=
radians
Tip: whenever y equals a number, the line is horizontal and the slope is 0. if the number equals x, the line will be vertical and there is no slope.
