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:

<u>Answer:</u>
- The number 9,648 in expanded form is '9,648 = 9,000 + 600 + 40 + 8'.
<u>Step-by-step explanation:</u>
<em>Expanded form is a way to expand a number in addition form. Since the '9' is in the thousands place, it's value will be 9,000. With 6 in the hundreds place, it's value will be 600. This will occur the same thing with the tens and the ones place. Now, the answer to the question is explained below.</em>
- => 9,648 = 9,000 + 600 + 40 + 8
Hence, <u>the number 9,648 in expanded form is '9,648 = 9,000 + 600 + 40 + 8'.</u>
Hoped this helped.
