Answer: 676
Step-by-step explanation:
The total number of letters in English alphabet {From A to Z} = 26
We assume that the repetition of letters is allowed.
If we fix H at the first position , then the number of ways to make three-letter strings that begin with H is given by :-
Hence, the number of ways to make three-letter strings that begin with H is 676.
Answer:
Step-by-step explanation:
You see that there’re angles with 30 and 90 degrees that means that -> 180-(90+30)=60 (measurement of the third angle)
Here you’ll need to use the 30,60,90 degree triangle rule:
The opposite side of 30 degree will be y
30->y
90->2y->12√3 => y=6√3
60->y√3->x => 6√3x√3=6x3=18
To understand the rule better you can check the picture below.Wish it will help you!Good luck!
Given expression : .
We need to apply power property of logs to rewrite it.
According to log rule of exponents:
If we compare given expression with the rule the exponent part is f, base is 6.
Therefore, we need to bring exponent f in front of log.
Therefore, .
