Original locations:
Annie: (5, -11)
Barbara: (-7, 13)
Note that the midpoint between two points (x₁, y₁) and (x₂, y₂) is
[(x₁+x₂)/2, (y₁+y₂)/2]
Therefore the meeting place has coordinates
[(5-7)/2, (-11+13)/2] = (-1, 1)
Barbara ends up at (-5, 5).
The positive difference in the y-coordinates between (-1, 1) and (-5, 5) is
5 - 1 = 4

Answer:
~1383.5 meters cubed
Step-by-step explanation:
(17.6 x 17.6 x 13.4) ÷ 3 = ~1383.5
Answer:
Step-by-step explanation:
The equation of this circle is (x - 3)^2 + (y - 3)^2 = 12^2.
Let's substitute the coordinates of the given point and compare the results to the above equation: do they produce a correct statement?
(-6 - 3)^2 + (-5 - 3)^2 = ?
9^2 + 8^2 = 145
Because r = 12, the above result would need to be 144, not 145, if the given point were actually on the circle. We must conclude that (-6, -5) lies just outside the circle.
81 + 64 = 144
