Using a geometric sequence, it is found that after 3 rounds, 8 teams are left.
In a geometric series, the quotient between consecutive terms is always the same, and it is called common ratio q.
The general equation of a geometric series is given by:
In which is the first term.
In this problem:
- 64 teams were invited, thus .
- After each round, half the teams are eliminated, thus .
The <u>number of teams after 3 rounds</u> is the 4th term of sequence, as the first is the initial number(0 rounds), thus:
After 3 rounds, 8 teams are left.

I think the answer is 49 because if you add 17 and 23 you get 40 then subtract 40 from 89 you get 49. I hope this helped!
The answer is A. Y=square root of 2x
Answer:
D
Step-by-step explanation:
The range is the values of y covered by the graph
The graph on the left shows y going to - ∞
The graph has its maximum value at 4 ( turning point )
The range is therefore
- ∞ < y ≤ 4
Answer:
negative number
Step-by-step explanation:
-1
1/4 of -1 = -1/4
-1/4 is greater than -1
