When clothes are sold by an second hand store, the store takes some of the money, and the donor gets the rest. The graph below shows how much money a donor makes given the total amount of money brought in by the second hand store from sales of a piece of clothing. Identify the constant of proportionality between dollars earned by the donor and dollars brought in by the second hand
store.
Write an equation relating dollars earned by second hand store, , to dollars earned by the donor, x.

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.

Which of the following is a solution of z^6 = 64i? 2(cos105° + isin105°) 2(cos120° + isin120°) 2(cos135° + isin135°) 8(cos15° + isin15°)
