2 In the accompanying diagram of circle O, m m What is the measure of CD?
A 104°

B 80°

C 52°

D 40°

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

Simplify this expression. 8x 16(x + y)

Cos^2x+cos^2(120°+x)+cos^2(120°-x)i need this asap. pls me
