The number of players in a tennis tournament is reduced by half (50%) after every round. in round 1 there are 256 player, in round 2 there are 128 players, and so on. which explicit formula models this situation? how many player compete in round 7?
i need

where .

The number of players compete in round 7 will be 4.

Step-by-step explanation:

The number of players in a tennis tournament is reduced by half (50%) after every round. In round 1 there are 256 players, in round 2 there are 128 players, and so on.

So, the number of players is multiplied by gives the number of players in the next round.

Therefore, the explicit function of number of players in nth round is given by  

where .

Therefore, the number of players compete in round 7 will be . (Answer)

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
