Answer:
The volume of the cone would be 2513.27 cubic feet.
Given:
The exponential function is:
![y=630(0.94)^x](https://tex.z-dn.net/?f=y%3D630%280.94%29%5Ex)
To find:
The percentage rate of increase or decrease.
Solution:
The general exponential function is:
...(i)
Where, a is the initial value, |r| is the growth rate in decimals if r>0 and |r| is the decay rate in decimal if r<0.
The exponential function is:
![y=630(0.94)^x](https://tex.z-dn.net/?f=y%3D630%280.94%29%5Ex)
It can be written as:
![y=630(1-0.06)^x](https://tex.z-dn.net/?f=y%3D630%281-0.06%29%5Ex)
...(ii)
On comparing (i) and (ii), we get
![r=-0.06](https://tex.z-dn.net/?f=r%3D-0.06)
Since r is negative, therefore the given function is a decreasing or decay function.
Now,
So, the rate of decrease is 0.06. Multiply this number by 100 to get the percentage.
![0.06\times 100=6\%](https://tex.z-dn.net/?f=0.06%5Ctimes%20100%3D6%5C%25)
Therefore, the rate of decrease is 6%.
