Answer:
4 units.
Step-by-step explanation:
Let's use a ratio
72 : 360
8 : 40
1 : 5
The arc is
of the total circumference.

The arc length is 4
Answer:
(6, -3)
Step-by-step explanation:
The actual coordinates are x = -6 and y = 3
If we rotate 180 degrees and the center of rotation is at (0,0), all we need to do is invert the signal of each axis, that is, we invert the sign of the original x-coordinate and invert the signal of the original y-coordinate.
So the final x-coordinate is - (-6) = 6
And the final y-coordinate is - (3) = -3
So the coordinates will be (6, -3).
Answer:
The third choice
Step-by-step explanation:
a relation is a function if an input has at most one output for a given input
Choices 1, 2 and 4 are not functions as they have two different outputs for the same input. (See the red ovals)
Combine like terms to get 2y2-2y+4x
The correct value is -10.
7 plus negative 10 equals negative 3.
Negative 3 times 4 equals -12.
Or, (7+-10=-3•4=-12)
