Answer:
The answer is B. 50
Step-by-step explanation:
180-105=75
75+55=130
180-130=50
Point P' would be in the II quadrant; the answer is b
Answer:
see below
Step-by-step explanation:
The radius is 1/2 of the diameter
r = 1/2 d
r = 1/2(4) = 2 inches
The circumference is given by
C = 2 * pi * r
C = 2 * pi * 2
C = 4 pi inches
Using 3.14 as an approximation for pi
C = 12.56 inches
The slope of a line often referred to as the (
) is the rate of change in a line. It can be found using the following formula.
Where (
) and (
) are points on the line. For each problem, substitute the points on the line into the formula and solve for the slope.
1. 
(0, 2), (-2, 1)
2. 2
(-2, -1), (0, 3)
3. 4
(1, 0), (2, 4)
4. 1
(6, 2), (2, -2)
5.
(-1, 1), (4, 4)
6. 
(-7, 4), (2, 1)
7. 0
(5, -3), (-2, -3)
8. 
(-3, 2), (2, 7)
9. 8
(2, 16), (3, 24)
The slope of the line is -3/4
