Answer:
r = 2. The center is at (0, 3).
Step-by-step explanation:
Compare the given x ^ 2 + (y - 3) ^ 2 = 4 to the standard equation
(x - h)^2 + (y - k)^2 = r^2.
It becomes obvious that h = 0, k = 3 and r = 2. The center is at (0, 3).

Step-by-step explanation:
Answer: a. Every ratio yx for related pairs of x and y is equivalent.
Step-by-step explanation: The proportionality between two variables x and y is established using the proportionality relation.
x = ky where k is a constant and k = x / y. Hence every ratio of both numbers for a rated pair are equivalent once x and y ≠ 0
