Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = -5 - 5 cos θ

The graph of polar equation is symmetric about the x-axis.

Step-by-step explanation:

The given polar equation is

If and lie on the graph then the graph of polar equation is symmetric about the x-axis.

Substitute in the given equation.

Cosine is an even function.

Point lies on the graph, therefore the graph of polar equation is symmetric about the x-axis.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
