Look at the attached figure. We define the unit circle as a circle with center
in the origin (0,0) and radius 1.
Then, we consider a point P on the circumference. We call
the angle between the positive half of the x axis and the radius AP.
We define

As you can see, ACD is a right triangle, and so we have

But since we know that AD is the cosine, AC is the sine, and AP is the radius (which is 1, and remains 1 when squared), we have just found out that

Answer:
Company B pays more!
Step-by-step explanation:
All you have to do is...
25,000x10=250,000

1,600x10=16,000
= 266,000(company a)
28,500x10=285,000
+
700x10=7,000
= 292,000(company b)
Answer:
vertex (-3 , 7)
Step-by-step explanation:
vertex (h, k) f(x) = a | x - h | + k
f(x) = |x + 3|+ 7 , h = - 3 and k = 7
vertex (-3 , 7)
