Answer:
Center: (0, 6); radius = 4
Step-by-step explanation:
x^2 + y^2 - 12y + 20 = 0
We must complete the square in y.
x^2 + y^2 - 12y = -20
x^2 + y^2 - 12y + 36 = -20 + 36
x^2 + (y - 6)^2 = 16
(x - 0)^2 + (y - 6)^2 = 4^2
Center: (0, 6); radius = 4

Answer:
35
Step-by-step explanation:
Monday=x
Tuesday=7
Wednesday=1/2
Thursday=21
Therefore,
x+7/2=21
=x+7=2*21
=x+7=44
=x=44-7
=x=35
