Answer:
(x - 3)^2 + (x + 2)^2 = 4
Step-by-step explanation:
Equation of circle:
(x - h)^2 + (x - k)^2 = r^2
(h, k) = (3, -2)
r = 2
(x - 3)^2 + (x - (-2))^2 = 2^2
(x - 3)^2 + (x + 2)^2 = 4
Answer:
Part 1)
Part 2)
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
Part 1)
in this problem we have
so
substitute in the formula
therefore
Part 2)
in this problem we have
so
substitute in the formula
therefore
5 gallons is 0.66 cubic feet, 0.5 cubic feet per container.
Answer:
Step-by-step explanation:
The formula for a geometric sequence is
where n is the position number in the sequence, a1 is the first number in the sequence, and r is the common ratio. For us,
n is 14, a1 is 5, and the common ratio (the number we multiply by each number to get to the next one in line) is -2.
and
and
so
