Answer:
The sequence diverges.
Step-by-step explanation:
A sequence
converges when
is a real number.
In this question, the sequence given is:

The cosine is always going to be between -1 and 1, so for the convergence of the sequence, we look it as:
. So

Since the limit is not a real number, the sequence diverges.
Just around the 15 and 3. So it would be
(15-3)x4+9=57
This is because (15-3)= 12
12x4=48
48+9= 57
Inverse relationships are of the form xy=k or if you prefer y=k/x so to find the constant we can say:
18(0.25)=k=4.5
So you could say: IR=4.5 or I=4.5/R

= 1
Answer:
In order to solve this algebraic expression, you need to get the variable x by itself
Step 1: subtract 4 from each side
4-4+7x=-24-4 (4-4=0, those cancel out) (-24-4=-28)
7x=-28
Step 2: divide both sides by 7
7x/7=-28/7 (7x/7=x) -28/7=-4)
Your final answer would be x=-4
