Answer:
A is the anwer 99 degrees
Answer:
292,968
Step-by-step explanation:
As we know,
Sum of a geometric sequence (S) = 
where,
a = first term of sequence,
r = the constant ratio,
n = number of terms in sequence.
So, according to the question,
a = 3,
r = 5,
n = 8.
by substituting the values in the above formula, we get;
⇒ 
⇒ 
Substitute the answer: therefore, 8-8/2+8= 0/10 in fraction form, but as you feather simplify 0 divide by 10 you'll get the answer as 0.
Answer:
A is neither, B is direct, and C is inverse
Step-by-step explanation
In B, as x increases y also increases, in C as x increases y decreases, and in A it's neither because it's not one line (if you graphed it you would understand what I mean). Though I have no idea what is constant of variations.
