Answer:
![T_n = 200 * (\frac{1}{5})^{n-1](https://tex.z-dn.net/?f=T_n%20%3D%20200%20%2A%20%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7Bn-1)
Step-by-step explanation:
Given
![Sequence: 200,40,8](https://tex.z-dn.net/?f=Sequence%3A%20200%2C40%2C8)
Required
The nth term
The given sequence is a geometric sequence.
So, first we identify the first term
![a = 200](https://tex.z-dn.net/?f=a%20%3D%20200)
Calculate common ration
or ![r = \frac{8}{40}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B8%7D%7B40%7D)
![r = \frac{1}{5}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B1%7D%7B5%7D)
So, the nth term is:
![T_n = ar^{n-1](https://tex.z-dn.net/?f=T_n%20%3D%20ar%5E%7Bn-1)
![T_n = 200 * (\frac{1}{5})^{n-1](https://tex.z-dn.net/?f=T_n%20%3D%20200%20%2A%20%28%5Cfrac%7B1%7D%7B5%7D%29%5E%7Bn-1)
Answer:
Zac Made 28 Jackets
Step-by-step explanation:
The way I solved it is by first dividing 48 by 2.
After that I subtracted 8 from Tyra's jackets and then guessed and checked.
I eventually got to the point where i found that Tyra made 20 jackets and Zac made 28 making up to 48 jackets in total.
So what you do is go 5(3y+5)-4y=14 which equals 15y+25-4y=14 which turns into 11y+25=14 than you move the 25 over which equals 11y=-11 so y=-1 then you enter -1 in for y which looks like 5x-4(-1)=14 than you solve that which is 5x+4=14 than you move the 4 over and you get 5x=10 than x=2
x=2
y=-1
