Answer:
21
Step-by-step explanation:
There are 2 halfs in 1 number.
Lets start with your whole number: 10
You double 10 because there are two halfs in each whole number making it equal 20.
Now you have 3/4
There would be 1 half in this number because it's a fraction and not a whole number.
You would be left over with 1/4
Your answer is 21
Hope this helps! Goodluck
Answer:

Step-by-step explanation:
The cotangent function can be rewritten by trigonometric relations, that is:
(1)
By taking approach the periodicity properties of the cosine and sine function (both functions have a period of 360°), we use the following equivalencies:
(2)
(3)
By (2) and (3) in (1), we have following expression:

If we know that
and
, then the result of the trigonometric expression is:


Answer:
2
Step-by-step explanation:
= (1--5) / (4-1)
= 6/3
