Asporting goods store uses quadratic equations to monitor the daily cost and profit for various items it sells. the store’s daily profit, y, when soccer balls are sold at x dollars each, is modeled by y=6x^2 + 100x - 180. why is there an interval over which the graph decreases? a. if the store sells more soccer balls, they can decrease the price. b. if the soccer balls are returned for a refund, the store will lose money. c. if the soccer balls are too expensive, fewer will be sold, reducing profit.

Which expression is equivalent to (3^2)^-2 a.-81 b.-12 c.1/81 d.1/12

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126 a. the attendance was never the same at both plays. b. the attendance was the same on day 5. the attendance was 231 at both plays on that day. c. the attendance was the same on day 13. the attendance was 295 at both plays on that day. d. the attendance was the same on days 5 and 13. the attendance at both plays on those days was 231 and 295 respectively.

Find the coordinates of point x that lies along the directed line segment from y(-8, 8) to t(-15, -13) and partitions the segment in the ratio of 5: 2.
