The equation in rectangular coordinates. (x - 1)² + y² = 1
<h3>What are different Coordinate Systems ?</h3>
There are many types of coordinate system depending upon the usage and ease of working , Spherical , Rectangular , Cylindrical , Polar are the examples of Coordinate System.
It is given that the equation in polar coordinates is r = 2 cosθ
To change in rectangular coordinates
The relation between polar and rectangular coordinate is
x = r cosθ and y = r sinθ
x² + y² = r²
r = 2 cosθ
r² = 2r cosθ
r² = x
so the equation in rectangular coordinate system becomes
x² + y² = 2x
x² - 2x + y² = 0
x² - 2x + 1 + y² - 1 = 0
(x - 1)² + y² = 1
This represents the equation in rectangular coordinates.

Answer:the percent of increase in price is 7.69%
Step-by-step explanation:
The yearbook was sold for $26 at the beginning of the year. This means that the initial price of the year book was $26.
The price has increased to $28. The amount by which it was increased would be the current price - the initial price. It becomes
28 - 26 = $2
The percent of increase in price would be
Increase/initial price × 100
It becomes
2/26 × 100 = 7.69%
Answer: if it's 1/4 it's 20 because if you multiply 1/4 x10 it equals 2.5 and multiply that by 2 then it equals 5 and 10x2 =20
Hello,
the answer is 4' + 4' + 6' + 6' = 20'
