Answer:
(x − 3)² + (y − 4)² = 5
Step-by-step explanation:
The equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center and r is the radius.
First use the distance formula to find the radius:
d² = (x₂ − x₁)² + (y₂ − y₁)²
r² = (2 − 3)² + (6 − 4)²
r² = 1 + 4
r² = 5
Given that (h, k) = (3, 4):
(x − 3)² + (y − 4)² = 5

Answer:
10 months
Step-by-step explanation:
Our initial cost is $55
Our variable cost is $19.50 / month (lets call it 19.50m)
Chelsey has $250 dollars to spend.
Our equation would be as follows:
19.50m + 55 = 250 (this tells how many months plus the initial cost will be covered by the 250 dollars)
19.50m +55 -55 = 250 - 55
19.50m = 195
19.50m/19.50 = 195/19.50
m = 10
Chelsey can afford the initial membership fee and 10 months of club membership.
Answer:
See below.
Step-by-step explanation:
Positive association is when the line has a positive slope, and the line progresses upwards.
E.g. When a car is traveling, as time progresses, the distance traveled increases.
Negative association is when the line has a negative slope, and the line declines.
E.g. When a car is traveling, as time progresses, the amount of gasoline decreases.
No association is when there is no slope between points, nor is there a line.
