Answer:
Center: (-5,3)
Radius: 4
Step-by-step explanation:
Let's first start with the equation of a circle:
(x - h)^2 + (y - k)^2 = r^2
The center is (-h, -k)
Which is: (-5,3)
Lastly our radius is
Radius = 4

It it would take Andrew less amount of time than Bailey so think if it took him 22 hours every day for 9 days than it took Bayli 24 hours every day for 9 days then u would compare them then u would have your anaer

Answer:
Circle
Step-by-step explanation:
r = 2 cos θ
Multiply both sides by r.
r² = 2r cos θ
Convert to rectangular.
x² + y² = 2x
x² − 2x + y² = 0
Complete the square.
x² − 2x + 1 + y² = 1
(x − 1)² + y² = 1
This is a circle with center (1, 0) and radius 1.
