I hope this is correct if not I am so so so so so so sorry
Answer:
24.
Step-by-step explanation:
We can use the factorial function to find the number of unique arrangements in a word.
There are 4 unique characters in 'OPAL'. As such, 4! = 24.
In the case that there were repeating characters, such as 'OPALA', then we would divide by the factorial of the number of repeating letters. That looks something like this:

Hope this helped.
Sin x = square root (2) / 2
In order for us to get for cos x and tan x, first we need to know what
Hypotenuse, Adjacent, and Opposite sides.
sin x = opposite / hypotenuse.
adjacent = square root (hypotenuse^2 - opposite^2)
adjacent = square root (2^2 - square root(2)^2)
adjacent = square root (4 - 2)
adjacent = square root (2)
cos x = adjacent / hypotenuse
tan x = opposite / adjacent..
cos x = square root (2) / 2
tan x = square root (2) / <span>square root (2) = 1
So, </span>cos x = square root (2) / 2 and tan x<span> = 1</span>
Answer:
3 or 6/2
Step-by-step explanation:
when there are two subtraction signs it can be taken as a plus sign
1/2 + 5/2
1/2 + 5/2 = 6/2
6 / 2 = 3
3 is your answer
