Answer:
1/9
Step-by-step explanation:
You can put in any 2 numbers that would make a-b=2 true, so if you use a=4 and b=2, then 3^2/3^4=1/9. This is still true with any 2 numbers that make a-b=2 true. Hope this helps!
True because tan(20)=2.1 and cot(20)=is o.44
Answer:

Step-by-step explanation:
To find the nth term of a geometric sequence, you have the general formula:

where a1 is the first term and r is the common ratio. In order to find the 4th term, we can substitute what we have(n is 4 because we are looking for the fourth term):
135 = 
135 = 
135 = 

Now, we can substitute the first term back in:

Answer:
3 3/4 in length is equal to 22.5 picas
Step-by-step explanation:
If there are 6 picas in 1 in, then in 3 3/4 in, we will first take this to decimal form, which is
3.75 in
Therefor 3.75 in = 6 picas × 3.75 = 22.5 pisca
