Answer:
D
Step-by-step explanation:
y = cos ^- 1 (x)
The Function y = cos -1x = arccos x and its Graph: Since y = cos -1x is the inverse of the function y = cos x, the function y = cos -1x if and only if cos y = x. This leaves the range of the restricted function unchanged as [-1, 1].
-n← 2 2/3
first combine like terms, and then simplify
1410
-6 times 5 is -30
47 times -30 is -1410
