Hello,

Answer B: y-axis only
==================

Answer:

<h2>y-axis only.</h2>

Step-by-step explanation:

The given equation is

r=2+3sin \theta

Notice that this equation is in polar form.

If (r, \theta) can be replace with (r, \pi - \theta) or (-r, -\theta), then the graph is symmetric to the line \theta = \frac{\pi}{2}, which is a vertical line.

Let's evaluate the given equation.

r=2+3sin \theta=2+3sin(\pi -\theta)= 2-3sin(- \theta)

But, sin(-\theta)=-sin \theta

So,  r= 2-3sin(- \theta)=2-(-3sin\theta)=2+3sin\theta=r

Notice that the change produces the same equation.

Therefore, the given polar expression is symmetric to \theta  = \frac{\pi}{2}, which is the y-axis only in the coordinate system.

So, the right answer is y-axis only.

BRAINLIEST + POINTS
Amanda [17]

The company matches up to 8%.

Multiply her salary by 8%:

66410 x 0.08 = $5,312.80


Her company will match 50% ( which is half the amount)

Divide the 8% total by 2:

5312.80 / 2 = 2656.40


The answer is B.

2.68/2 = 1.34

The better buy is 3 for $3.33

1.11 x 12 = 13.32

1.34 x 12 = 16.08
