We will see that the solution in the given interval is: x = 0.349 radians.
<h3>How to solve equations with the variable in the argument of a cosine?</h3>
We want to solve:
cos(3*x) = 1/2
Here we must use the inverse cosine function, Acos(x). Remember that:
cos(Acos(x)) = Acos(cos(x)) = x.
If we apply that in both sides, we get:
Acos( cos(3x) ) = Acos(1/2)
3*x = Acos(1/2)
x = Acos(1/2)/3 = 0.349
So x is equal to 0.349 radians, which belongs to the given interval.

Answer:
1676
Step-by-step explanation:
The store started with 32500 items and finished the day with 30824 items.
Intial value = 32500
Final value = 30824
Difference = Initial value - Final value = 32500 - 30824 = 1676
The store sold 1676 items in the day

Answer:
560
Step-by-step explanation:
8 out of 10 is 80%, so then the answer would be 80% of 700, which would be 560
