Answer: 15,120

Step-by-step explanation:

The number of permutations of n objects taken r at one time ^nP_r is calculated by the following formula:

^nP_r=\frac{n!}{(n-r)!}

Now, the given  expression is ^9P_5

by using the above formula , we get

^9P_5=\frac{9!}{(9-5)!}\\\\=\frac{9!}{4!}\\\\=\frac{9\times8\times7\times6\times5\times4!}{4!}\\\\=9\times8\times7\times6\times5=15120

Hence, ^9P_5=15,120

Would the following situation be better represented by a linear function or an exponential function:
anastassius [24]

Answer:

Exponential function

Step-by-step explanation:

It is better if the situation on ground is represented by an exponential equation.

This is because, since we have the number of teams reducing by exactly half at every playoff round, this means that we have a base of 2 which can be raised to a negative power since we are talking about a decrease.

We can then place the number of rounds as an adjoining power to what the two is raised and this easily will get us the number of teams which is eventually decreased at every point of the playoffs

In order to find the other end point we must know where the End point is.

·(5,-3)

In order to find out the new point we must know how long the line segment is.

·8 units.

Knowing this we would use the equation ΔY/ΔX to find the new point

·ΔY= Y²-Y
·ΔX=X²-X

Knowing this we just plug our points in, and we use process of elimination to get our answer.

First we will try choice A.

· (5,-3) 
·(-3,-3)

To get from Y²⇒Y= 8 Units, and to get from X²⇒X=0 Units.

·8+0=8

-In conclusion your answer is A, i hope this is the answer you are looking for, feel free to post your questions here on brainly in the future.
