Determine if the graph is symmetric about the x-axis, the y-axis, or the origin.

r = 2 + 3 sin θ

choices:
no symmetry
y-axis only
x-axis only
origin only

Step-by-step explanation:

The given equation is

Notice that this equation is in polar form.

If can be replace with or , then the graph is symmetric to the line , which is a vertical line.

Let's evaluate the given equation.

But,

So,  

Notice that the change produces the same equation.

Therefore, the given polar expression is symmetric to , which is the y-axis only in the coordinate system.

So, the right answer is y-axis only.

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
