Let's check.
x = 5π/24
4x = 5π/6
cos 4x = cos(5π/6) = cos 150° = -√3/2
cos² 4x = (-√3/2)^2 = 3/4
4 cos² 4x -3 = 4 (3/4) - 3 = 0
Answer: TRUE
Answer:
X = -2
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
1+1=2 then times that by 0 which gives you 0 then -1 the one gives you minus 1
Ball + bat = 1.10
Bat = 1.00 more than ball
1.00 - 1.10 = .10
The ball costs 10 cents.
Answer:
20%
