What is the rectangular form of the polar equation?

r−rcosθ=6

Step-by-step explanation:

r − r cos θ = 6

r = r cos θ + 6

r² = (r cos θ + 6)²

x² + y² = (x + 6)²

x² + y² = x² + 12x + 36

y² = 12x + 36

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

a)(x-2)^2+(y-1)^2=9
