Answer:
the answer is B. -5/4.....
2+ -8 it's the same as 2-8, the last one it's correct
Answer:
Perpendicular lines have slope that are negative reciprocals.
The slope of the perpendicular line is M = -1/3.
Step-by-step explanation:
(4,-1) --> X = 4, Y = -1, M = -1/3
y = Mx + b
-1 = (-1/3)*4 + b
-1 = (-4/3) + b
-3/3 = (-4/3) + b
-3 = -4 + 3b
1 = 3b
b = 1/3
y = (-1/3)X + 1/3
Answer:
107.94 inches
Step-by-step explanation:
Circumference = 2 pi r = 6.28 *31 = 194.28
1% arc = 3.6 = 1.9428
55.56% of 360=200.016
55.56% of 194.28 =107.94
You can try using this guide to apply to arc segments
The radius is 31inch if it was a prime factor of 360 then you could use the equation arc = radius / no of segments
Ifthe circle had 30 inch radius then 360/30 = 12
Then divide by the 200/30 = 6.66
The circumference then would be similar 114.44inch
