Which points are the approximate locations of the foci of the ellipse? round to the nearest tenth. (−2.2, 4) and (8.2, 4) (−0.8, 4) and (5.2, 4) (3, -1.2) and (3, 9.2) (3, 1.3) and (3, 6.7) ! im !

To solve this problem you must apply the proccedure shown below:
 1. You have to find the distance from the center to the focus, as below:
 c=√(a^2-b^2)
 Where a is the major radius and b is the minor radius.
 2. Therefore, by the graph, you have:
 a=6
 a^2=36
 b=3
 b^2=9
 3. When you substitute the values, you obtain:
 c=5.2
 4. As you can see in the graph, the coordinates of the center is (3,4), then, the locations of the foci:
 3+c=8.2
 3-c=-2.2
 The answer is: (-2.2,4) and (8.2,4)

Ibelieve the total for the tip could be $21.90
