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.

step-by-step explanation:

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
