Each year the miller county country club sponsors a tennis tournament. play starts with 128 participants. during each round, half of the players are eliminated. what is the decay rate?
a.0.50
b.1
c.16
d.1.1

a. 0.50

Given : The initial number of participants =128

It is given that during each round, half of the players are eliminated.

Then, the number of players after first round =

Hence, the exponential decay equation for the given situation will be  :-

, gives the number of players after nth round.

On comparing with the standard exponential decay equation , where r is the rate of decay

We get the decay rate =

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
