Answer:
Average rate of change ![=-35.7084](https://tex.z-dn.net/?f=%3D-35.7084)
Step-by-step explanation:
Given function is
and we need to find average rate of change of the function from
.
Average rate of change ![=\frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D)
So,
![here\ b=5\ and\ a=1\\f(5)=480(0.3)^5\\=480\times0.00243=1.1664\\and\\f(1)=480(0.3)^1\\=480\times0.3=144](https://tex.z-dn.net/?f=here%5C%20b%3D5%5C%20and%5C%20a%3D1%5C%5Cf%285%29%3D480%280.3%29%5E5%5C%5C%3D480%5Ctimes0.00243%3D1.1664%5C%5Cand%5C%5Cf%281%29%3D480%280.3%29%5E1%5C%5C%3D480%5Ctimes0.3%3D144)
Average rate of change
![=\frac{f(b)-f(a)}{b-a}\\\\=\frac{f(5)-f(1)}{5-1}\\\\=\frac{1.1664-144}{5-1}\\\\=\frac{-142.8336}{4}= -35.7084](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D%5C%5C%5C%5C%3D%5Cfrac%7Bf%285%29-f%281%29%7D%7B5-1%7D%5C%5C%5C%5C%3D%5Cfrac%7B1.1664-144%7D%7B5-1%7D%5C%5C%5C%5C%3D%5Cfrac%7B-142.8336%7D%7B4%7D%3D%20-35.7084)
Hence, average rate of change of the function
over the intervel
is
.

Answer:
3.50$
Step-by-step explanation:
Since a nickel is 5 cents, you would do 5 x 60 which would equal 300, which is 3 dollars.
Since a penny is worth 1 cent, you would do 1 x 50 and get 50 cents, which is half a dollar.
3 + .5 = 3.50
Hope this helps!
