Answer:
5 gallons of water must be added.
10 gallons to start with
adding 'x' gallons of water final volume = 10 + x
.9 (10) = amount of vinegar
.1(10) = amount of water
amount of vinegar before and after water addition is constant
.9(10) = .6(10+x)
9 = 6 + .6x
3 = .6x
x = 5 gallons of water to be added

Answer:
The equation of a circle is
.
Step-by-step explanation:
-The equation of a circle is:
(where center is
, the point
and the radius known as
).
-Use the center (5,-4) and the point (5,-2) for the equation:

-Solve the equation:





-After you found the radius, use the center (5, -4) and radius 2 to get the equation of a circle:

-Then, after you have the equation, the radius needs to simplified by the exponent:
