Answer:
5
Step-by-step explanation:
If their average is 6 and there are three numbers in total, the total sum of the three numbers would be:
6×3 = 18
You know that two of them is 6 and 7, so you can find the last number easily.
18-6-7 = 5
3.
4^3 is equal to 64. Therefor log4(64) must be equal to 3.
Answer:
The proof is given below.
Step-by-step explanation:
Given: ( the correct question and ans is as follow )
sin (x + y) = 3sin ( x - y)
To Prove
tan x = 2 tan y
Proof:
Using the identities
we get
Now we will take sin x . cos y to the left hand side and cos x . sin y to the right hand side,we get
