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 =

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

faster, im not sure why but i know it is faster
