Answer:

104.8576

Step-by-step explanation:

I’m doing this to so I’m not sure but if you find the common ratio I got 4/5 you then multiply it by 320 to get f(4) then multiply 4/5 by the next number until you hit 8. Once I did that I got 104.8576.

Describe a real world situation that can be modeled by the equation y = 1/20x. be sure to describe what each variable represents
ivolga24 [154]
A real world example could be:
Consider x is time in minutes
Consider y is the amount of fish food required in grams

The equation could then represent how much food (in grams) that a fish needs to be fed x minutes after it was previously fed.

a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad 
a^n\implies \cfrac{1}{a^{-n}}
\\\\
-------------------------------\\\\
\cfrac{-9}{2x^5}\implies \cfrac{-3^2}{2x^5}\implies \cfrac{-3^2}{1}\cdot \cfrac{1}{2}\cdot \cfrac{1}{x^5}\implies -\cfrac{1}{3^{-2}}\cdot 2^{-1}\cdot x^{-5}
\\\\\\
-\cfrac{2^{-1}x^{-5}}{3^{-2}}
