Step-by-step explanation:
Given the function:
![d(t)= 12 (.72) ^ t](https://tex.z-dn.net/?f=d%28t%29%3D%2012%20%28.72%29%20%5E%20t)
is the depth of water in feet and
is the amount of time
To find:
The average rate of change for
in the interval [0, 4].
Solution:
The required rate of change in the time interval [0, 4] can be represented as:
Change in the function over the interval [0, 4] and the change in the interval.
OR
![\Rightarrow \dfrac{d(4)-d(0)}{4-0}\\\Rightarrow \dfrac{12 (.72) ^ 4-12 (.72) ^ 0}{4-0}\\\Rightarrow \dfrac{3.22-12 \times 1}{4}\\\Rightarrow \dfrac{3.22-12}{4}\\\Rightarrow \dfrac{-8.78}{4}\\\Rightarrow \bold{-2.195}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7Bd%284%29-d%280%29%7D%7B4-0%7D%5C%5C%5CRightarrow%20%5Cdfrac%7B12%20%28.72%29%20%5E%204-12%20%28.72%29%20%5E%200%7D%7B4-0%7D%5C%5C%5CRightarrow%20%5Cdfrac%7B3.22-12%20%5Ctimes%201%7D%7B4%7D%5C%5C%5CRightarrow%20%5Cdfrac%7B3.22-12%7D%7B4%7D%5C%5C%5CRightarrow%20%5Cdfrac%7B-8.78%7D%7B4%7D%5C%5C%5CRightarrow%20%5Cbold%7B-2.195%7D)
