Pair of listening post is 4000 feet apart they both pick up a soundboard one listening post records the sound 1.5 seconds after the other listing post assume sound travels app 1100 ft per second which equation can be used to determine the possible location to the origin of the sound x2/825 - y2/1,175 = 1
x2/680,625 - y2/3,319,375 = 1
x2/680,625- y2/4,000,000 = 1
x2/ 2,722,500-y2/13,277,500 = 1​

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.
