We have the following equation:

If we graph this equation we realize that in fact this is an ellipse with
major axis matching the y-axis. So we can recognize these characteristics:
1. Center of the ellipse: The midpoint C<span> of the line segment joining the foci is called the </span>center<span> of the ellipse. So in this exercise this point is as follows:
</span>
2. Length of major axis:
The line through the foci is called the major axis<span>, so in the figure if you go from -5, at the y-coordinate, and walk through this major axis to the coordinate 1, the distance you run is the length of the major axis, that is:</span>
3. Length of minor axis:
The line perpendicular to the foci through the center is called the minor axis. So in the figure if you go from -2, at the x-coordinate, and walk through this minor axis to the coordinate 2, the distance you run is the length of the minor axis, that is:
4. Foci:Let's find c as follows:

Then the foci are:

Answer:
Judy spent 55 minutes exercising
Step-by-step explanation:
Here, we want to know the amount of time Judy spent exercising.
We proceed as follows;
Mary spent 3 hours , sandy spent 50 minutes less than Mary. The amount of time spent by Sandy is thus 2hrs 10 minutes
Judy spent 1hr 15 min less, the amount of time he spent is thus
2hrs 10 minutes - 1 hr 15 min
2 hrs 10 minutes is same as 2(60) + 10 = 120 + 10 = 130 minutes
I hr 15 minutes = 60 + 15 = 75 minutes
The amount of time spent is thus 130 - 75 = 55 minutes
