Step-by-step explanation:
To know the hours of flight, subtract the departure time from the arrival time
so

Remember that Chicago and Dallas are in the same time zone
The answer is B
Because when you graph it in the calculator you get x=-136 and that goes to one to one function on the graph
I strongly recommend that you find an illustration of an ellipse that features the three distances a, b and c. You could Google "ellipse" and sort through the various illustrations that result, until you find the "right one."
There is an equation that relates a, b and c for an ellipse. It is a^2 = b^2 + c^2.
a is relatively easy to find. It is the distance from the center (0,0) of your ellipse to the right-hand vertex (20,0). So a = 20.
b is the distance from the center (0,0) of your ellipse to the right-hand focus (16,0). So b = 16. You could stop here, as it was your job to find b.
Or you could continue and find a also. a^2 =b^2 + c^2, so
here a^2 = 16^2 + 20^2. Solve this for a.
The circumference of a circle is 
Circumference = 
It says to leave in terms of pi which means that we won't solve 
Thus the answer is
.
