Answer:
n = -902.7
Step-by-step explanation:
n/-4.5 = 200.6
n = (-4.5)(200.6)
n = -902.7
equation of circle is given as
![{(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\](https://tex.z-dn.net/?f=%20%7B%28x%20-%20h%29%7D%5E%7B2%7D%20%20%2B%20%20%7B%28y%20-%20k%29%7D%5E%7B2%7D%20%20%3D%20%20%7Br%7D%5E%7B2%7D%20%5C%5C%20)
where (h,k) is center of cirlce and r is radius.
so lets figure out it from graph.
as we can see in graph center is at ( -1, 1)
radius is 4 units as shown in graph but we can calculate it. take any point on circle and calculate its distance from center. lets take point (3, 1)
now distance = √((3+1)^2+(1-1)^2)
= √16 = 4
lets put it in equation
(x +1)^2 + (y-1)^2 = 4^2
Answer:
i once took a pic of my HW on this app and got it finished in under 10 minutes
Answer:
70.4 meters
Step-by-step explanation:
A to B: 40²+10²=c² = 1600+100=c² = 1700=c² = c=√1700 = 41.23
B to C: 25²+15²=c² = 625+225=c² = 850=c² = c=√850 = 29.15
41.23+29.15=70.38
I will use this notation m arc AB to name the measure of the arc AC in degress, going from A to B counterclock wise.
Also, note that the measure of an arc is equal to the measure of the central angle from which the arc is generated.
With that:
1) m arc AB
m arc AB is equal to the angle AOC
The angle AOC is indicated to be 49°, so m arc AB is also 49°.
Answser: 49°
2) m arc ABC
m arc ABC is equal to 360° - angle COA = 360° - 107° = 253°
3) m arc BAC
m arc BAC is equal to angle AOB + angle COA
m arc BAC = 49° + 107° = 156°
Answer: 156°
4) m arc ACB
m arc ACB = 360 ° - angle AOB = 360° - 49° = 311°
Answer: 311°
