The coordinates of B would be C. (4, -8)
I got this because when reflecting over the x axis, the only value that changes is the y value. If you graph it out, the y value is the opposite while the x is the same.
Hope this helps!
Answer:
Step-by-step explanation:
Remark
What you don't know and what makes the problem confusing, is that where to the given arcs start and end. So I am going to say that both arcs start from E and 119 ends at D, and 174 ends at F which means that the arc FD is not known, but it is not hard to find.
The total number of degrees from beginning to end is 360 degrees. The formula for finding FD is
Formula
FD = 360 - (174 - 119)
The formula for x is (ED - FD)/2
Solution
Arc FD = 360 - (174 - 119)
Arc FD = 67
So x = (119 - 67) / 2
x = 52 /2
x = 26
18. s = 5r^2 + 7......making r the subject
s - 7 = 5r^2
(s - 7) / 5 = r^2...by taking the sqrt of both sides, it eliminates the ^2
( sqrt (s-7)/5) = r
19. h = ut - 1/2gt^2....u = 100, t = 1 4/5(or 9/5)...g = 6.4
h = (100)(9/5) - 1/2(6.4)(9/5^2)
h = 180 - 1/2(6.4)(3.24)
h = 180 - 3.2(3.24)
h = 180 - 10.368
h = 169.632 or 169 79/125
20. sorry..do not know this one
✡ Answer: True (yes) <span>✡
- -Why?
Because we can determine its a direct variation just based upon the x and y.

What class requires this tho? But its 300-850
