Which features are present in this polar graph?

Check all that apply graph is in image

A. Symmetry about the pole (0,0)
B. No symmetry
C. Symmetry about the polar axis theta = 0
D. Symmetry about the line theta = pi/2

C

Step-by-step explanation:

graph is symmetric about x-axis

or theta=0

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
