26. Given that tan Ø = 2.773 where 0< Ø< 3pie/2 , find the values of sin Ø and cos Ø 27. Given that tan Ø = -1.559 where 3pie/2< Ø< 2/pie, find the values of sin Ø and cos Ø

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

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

Find the value of x. give reasons to justify your solutions! h ∈ ig
