A school held a tennis tournament. After each round, one-forth of the players were eliminated. If there were 64 players at the start of the tournament, which equation models the number of players left after 6 rounds?​

Option B

Step-by-step explanation:

After each round of the tournament one-fourth players are eliminated.

That means the process of elimination will represent the exponential decay.

Equation of exponential decay is given by the expression,

Here, a = Initial number of players

r = Fraction of reduction in the number of players

y = Final number of players

n = Number of rounds

In the given question,

Initial number of the players (a) = 64

Fraction of reduction in the number of players (r) =

                                                                             = 0.25

Number of rounds (n) = 6

By substituting these values in the expression,

Therefore, Option B is the answer.

step-by-step explanation:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
