Answer:
graph attached
Step-by-step explanation:
A graph is a pictorial representation that represent the relationship between two or more things.
Cosine function is periodic with period 
. If the point 
lies on the graph, point 
will also lie on the graph where k is any integer.
Here,
![cos(x-\pi )=cos[-(\pi -x)]=cos(\pi -x)=-cos x](https://tex.z-dn.net/?f=cos%28x-%5Cpi%20%29%3Dcos%5B-%28%5Cpi%20-x%29%5D%3Dcos%28%5Cpi%20-x%29%3D-cos%20x)
Answer:
10 miles per hour
Step-by-step explanation:
Average velocity=distance covered/time in hours
Distance=2 miles
time=12minute
change minutes to hour=12/60 =0.2hrs
v=2÷0.2
v=10miles per hour
No, all regular polygons does not have even number of sides.
Suppose, heptagon which is a regular polygon which has 7 sides.
But, all the sides of any regular polygon are equal in length.
9x + x = 10x
the x has a one in front of it so you just add across
