Which inequality would result in the shaded solution on the unit circle to the right?
omeli [17]
<h3>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 \sec(x) = \frac{1}{\cos(x)}

I’m sorry but need help

These are pretty easy once you get the concept.

think of <em>random letter</em> (x) as the term y, so in the case of p(x)=-3+4x, its just asking what is y when x equals all those values.

so p(-2) = -3 + 4(-2), since its asking to plug in -2 for x, which equals -11

p(0) = -3 + 4(0)

= -3

p(5) = -3 + 4(5)

= 17
