Answer:
centre = (- 3, - 2) , radius = 1
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² + 6x + y² + 4y + 12 = 0 ( subtract 12 from both sides )
x² + 6x + y² + 4y = - 12
Use the method of completing the square on the x and y terms
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(3)x + 9 + y² + 2(2)y + 4 = - 12 + 9 + 4
(x + 3)² + (y + 2)² = 1 ← in standard form
with centre = (- (- 3), - (- 2)) and r² = 1, that is
centre = (- 3, - 2) and radius = 1

Answer:
money owed (in order): $850, $870.40, $891.29, $912.68
Step-by-step explanation:
The formula is
money owed = amount owed the previous week + amount owed previous week × interest rate (in decimal form)
so thats:
money owed = amount owed the previous week + amount owed previous week × 0.024
we can simplify that to:
money owed = amount owed the previous week x (1.024)
after 0 weeks:
$850 (just started, no interest added)
after 1 week:
$870.40
after 2 weeks:
$891.29
after 3 weeks:
$912.68
