Answer:
The equation to this question is "
"
Step-by-step explanation:
Given value:
So, the curve 
is basically a circle, which is defined in the attachment file.
To solve the problem you must know that to change from Cartesian to polar coordinates you must write:
x = rcos (θ)
Where "r" is the radius
Likewise y = rsin (θ)
Therefore, in the expression r = 3cos (θ) one can write r as:
r = x / cos (θ)
So:
x / cos (θ) = 3cos (θ)
x = 3cos ^ 2 (θ)
The same for y ...
y = rsin (θ)
y = 3cos (θ) sin (θ).
Finally the correct answer is option 2.
x = 3cos ^ 2 (θ) y = 3cos (θ) sin (θ).
It equals 2, explanation 1+1=2
Since Doug’s brother has double the amount of Doug we can just multiply the amount Doug has by 2.
$3,215*2 = $6,430
