Answer:
The third graph.
Step-by-step explanation:
The equations for the lines will be
P(x) = 2x-4
l(x) = -2x-4
When x = 0 both of these functions equal -4. The only graph where this happens is the third one.
You can check this by looking at the slopes and plugging in points.

Option A. 4 radians
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to

we have

substitute


step 2
Find the measure of angle 
we know that
The circumference of the circle subtends a central angle of 2π radians
so
using proportion
Find out the central angle by an arc length of 20 cm
