Step-by-step explanation:
true false true false
The answer would be 79% . you always move the decimal two spots to the right
The height of the tank is 12 inches
We are given this explicit formula :
![c(n) = -6 + 5(n - 1)](https://tex.z-dn.net/?f=%20c%28n%29%20%3D%20-6%20%2B%205%28n%20-%201%29%20)
In order to find eighth term let us plug n as 8 in this formula:
![c(8) = -6 + 5(8 - 1)](https://tex.z-dn.net/?f=%20c%288%29%20%3D%20-6%20%2B%205%288%20-%201%29%20)
subtracting 8-1 first using pemdas rule
![c(8) = -6 + 5(7)](https://tex.z-dn.net/?f=%20c%288%29%20%3D%20-6%20%2B%205%287%29%20)
multiplying 5 and 7
![c(8) = -6 + 35](https://tex.z-dn.net/?f=%20c%288%29%20%3D%20-6%20%2B%2035%20)
subtracting 35-6
c(8) = 29
So eighth term is 29.
4^5 is the answer. Hope it helps
