Answer:
cos(30) = (sqrt(3)/2) * cos(0)
Step-by-step explanation:
cos(0) = 1
cos(30) = sqrt(3)/2
Thus, we can write that:
cos(30) = (sqrt(3)/2) * cos(0)
Answer:990
Step-by-step explanation:
Since the president has 11 chances, the vice president has 10 chances, and the treasures has 9 chances, then there are 11 x 10 x 9 = 990 way of choosing them.
Or,
11P3 = 11!/(11 - 3)! = 11!/8! = (11 x 10 x 9 x 8!)/8! = 11 x 10 x 9 = 990
