2,124+1,728=3,852
They raised $3,852 dollars.

Step-by-step explanation:
<u>Given parabola:</u>
<u>Complete the square to convert the equation into vertex form:</u>
- y = x² - 8x + 13 =
- x² - 2*x*4 + 4² - 4² + 13 =
- (x - 4)² - 16 + 13 =
- (x - 4)² - 3
Answer:
50%
Step-by-step explanation:
50% because when there is only 2 variables and they are each 1 cup there is an even amount of stuff and when you ask for only one percentage that would be 50% because everything is even. Even if you asked for the percentage for the cup of raisins it would also be 50%. Hope this helps <3
Answer:
![r = -9](https://tex.z-dn.net/?f=r%20%3D%20-9)
Step-by-step explanation:
Given
![Sequence: 9,-81, 729,-6561...](https://tex.z-dn.net/?f=Sequence%3A%209%2C-81%2C%20729%2C-6561...)
Required
Determine the common ratio
The common ratio r is calculated using:
![r = \frac{T_n}{T_{n-1}}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7BT_n%7D%7BT_%7Bn-1%7D%7D)
Let ![n = 2](https://tex.z-dn.net/?f=n%20%3D%202)
So, we have:
![r = \frac{T_2}{T_{2-1}}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7BT_2%7D%7BT_%7B2-1%7D%7D)
![r = \frac{T_2}{T_1}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7BT_2%7D%7BT_1%7D)
From the sequence:
![T_2 = -81](https://tex.z-dn.net/?f=T_2%20%3D%20-81)
![T_1=9](https://tex.z-dn.net/?f=T_1%3D9)
So, the equation becomes
![r = \frac{-81}{9}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B-81%7D%7B9%7D)
![r = -9](https://tex.z-dn.net/?f=r%20%3D%20-9)
