<u>Answer:</u>
Mid point =
<u>Step-by-step explanation:</u>
We are given the coordinates of the end points of a line segment AB and we are to find the coordinates of its mid point.
The coordinates of the end points are: A (-1, -2) and B (6, 12).
We know the formula of the mid point:
Mid point =
So putting in the given values to find the mid point of line segment AB:
Mid point = =
9514 1404 393
Explanation:
a) see the attachment for a graph (red curve)
__
b) The piecewise defined function can be ...
__
c) The new cost function is ...
The charge is a flat $10 for any period up to 5 hours, then $1 per additional hour after that, prorated for partial hours. There is apparently no upper limit on parking time as there was with the original function. (The graph shown goes beyond 15 hours; the domain of the original C(x) is 0 to 12 hours.) For reference, the new cost structure is shown in blue in the attachment.
_____
<em>Additional comment</em>
Under the new structure, costs are significantly higher for short-term parking, and lower once the term exceeds 6 hours.
