4, a person is running around an elliptical track. the equation ofthe track is 4x2-25y2-200. runner (8, 0) bear 4x2 +25y2-200 (a) when the person is at the point (5, 2), her x-coordinate is increasing at 6 units per minute. describe how her y-coordinate is changing. (b) can she run in such a way that her x-coordinate changes at a constant rate? explain. (c) the inside of the track is heavily wooded, and she can- not see through the woods. there is a bear standing outside the woods at the point (8, 0). when she is at the point (5, 2), can she see the bear? explain.
