Answer:
Option C. The open and closed circles are reversed and the graph shifts up.
Step-by-step explanation:
From the graph of the functions (Attached below) you can check that for the interval 0 ≤x<1 the floor function takes the value 0 everywhere, also it has closed brackets at 0 and open brackets at 1.
On the other hand for the interval 0<x≤1 the ceiling function takes the value 1, also it has open brackets at 0 and closed brackets at 1.
For that reason we conclude that the open and closed circles are reversed and the graph shifts up.
The perimeter of the top is
.. 2*(6.5 ft +28 ft) = 69 ft
so the lateral area of the tank is
.. 69 ft * 13 ft = 897 ft^2
The area of the bottom is
.. 6.5 ft * 28 ft = 182 ft^2
The total area is 897 ft^2 +182 ft^2 = 1079 ft^2.
