Answer:
A
Step-by-step explanation:
5*10^3=5*1000=5000
5*10^4=5*10000=50000
The radius is 4.99, im sure
(2,0)
(-6,0)
I just inserted the equation into a graphing calculator. Kinda lazy tonight :/
343 is a cube root of 7. Its surface area is 7

Answer: Choice B</h3>
Explanation:
Cosine is positive in quadrants I and IV, but quadrant IV isn't shaded in so we can rule out choice A.
Sine is positive in quadrants I and II. So far it looks like choice B could work. In fact, it's the answer because sin(pi/6) = 1/2 and sin(5pi/6) = 1/2. So if 0 ≤ sin(x) < 1/2, then we'd shade the region between theta = 0 and theta = pi/6; as well as the region from theta = 5pi/6 to theta = pi.
Choice C is ruled out because tangent is positive in quadrants I and III, but quadrant III isn't shaded.
Choice D is ruled out for similar reasoning as choice A. Recall that
