64 teams participate in a softball tournament in which half the teams are eliminated after each round of play.
a. write a formula to model the number of teams remaining after any given round of play.

Number of teams remaining after n rounds of play, p(n) = 2⁶⁻ⁿ

Step-by-step explanation:

This is an example of geometric progression,

Let p(n) represents the number of participants remaining after n rounds of play.

First term = 64

We have

Number of teams remaining after n rounds of play, p(n) = 2⁶⁻ⁿ

the image of (6, 9) under a dilation is (4, 6). the scale factor is
