Answer:
do you have a picture of this
I think that the answer would be two triangles.
The function and the first value stated for x are confusing.
Doing some research, I found that the problem is to evaluate the function
![f(x)=4.7^x](https://tex.z-dn.net/?f=f%28x%29%3D4.7%5Ex%20)
for x = - 1 and x 2.
The solution is:
1) For x = - 1
![f(-1)=4. 7^{-1} =4. (1/7)=4/7](https://tex.z-dn.net/?f=f%28-1%29%3D4.%207%5E%7B-1%7D%20%3D4.%20%281%2F7%29%3D4%2F7%20)
2) For x = 2
The different possible mixtures can you make is 1716
.
<u>Step-by-step explanation:</u>
Given that,
- The total number of flavors available in the shop = 13 flavors
- The number of flavors you need to choose = 6 flavors
Here, we have to use the formula for combination,
nCr = n! / r! × (n-r) !
where,
- n is the total number of flavors
- r is the number of flavors you need to choose
⇒ 13C6 = 13 ! / 6! × (13-6)!
⇒ 13! / (6! × 7!
)
⇒ 13 × 12 × 11 × 10 × 9 × 8 × 7! / (6! × 7!
)
⇒ 13 × 12 × 11 × 10 × 9 × 8 / 6!
⇒ 13 × 12 × 11 × 10 × 9 × 8 / 6 × 5 × 4 × 3 × 2 × 1
⇒ 1716
Therefore, you can 1716 different possible mixtures.
