this gives u 2/9
Answer:
Step-by-step explanation:
To find the number of different ways she can stack 3 of them in a tower, we need to use the formula:
![_{n}P_{k}=\dfrac{n!}{(n-k)!}](https://tex.z-dn.net/?f=_%7Bn%7DP_%7Bk%7D%3D%5Cdfrac%7Bn%21%7D%7B%28n-k%29%21%7D)
n = 4
k = 3
![_{n}P_{k}=\dfrac{4!}{(4-3)!}](https://tex.z-dn.net/?f=_%7Bn%7DP_%7Bk%7D%3D%5Cdfrac%7B4%21%7D%7B%284-3%29%21%7D)
![_{n}P_{k}=\dfrac{4!}{1!}](https://tex.z-dn.net/?f=_%7Bn%7DP_%7Bk%7D%3D%5Cdfrac%7B4%21%7D%7B1%21%7D)
![_{n}P_{k}=\dfrac{4*3*2*1!}{(1)!}](https://tex.z-dn.net/?f=_%7Bn%7DP_%7Bk%7D%3D%5Cdfrac%7B4%2A3%2A2%2A1%21%7D%7B%281%29%21%7D)
![_{n}P_{k}=\dfrac{4*3*2*1!}{1}](https://tex.z-dn.net/?f=_%7Bn%7DP_%7Bk%7D%3D%5Cdfrac%7B4%2A3%2A2%2A1%21%7D%7B1%7D)
![_{n}P_{k}=\dfrac{24}{1}](https://tex.z-dn.net/?f=_%7Bn%7DP_%7Bk%7D%3D%5Cdfrac%7B24%7D%7B1%7D)
Answer:
It's an irrational number

Answer:
x - intercepts: (-5,0), (5,0), (7,0)
I'm not sure if you would count these, but x and y also have the intercept of (0,0).
Answer:
It would take Jared 2 hours to finish mowing 3 acres at that rate.
Step-by-step explanation:
