A farmer is tracking the number of soybeans his land is yielding each year. He finds that the function f(x) = −x2 + 20x + 100 mo

Aliun [14]

Answer:

The average rate of change = -10

The crop yield decreased by 10 pounds per acre from year 10 to year 20.

Step-by-step explanation:

A farmer is tracking the number of soybeans his land is yielding each year. He finds that the function $f(x) =-x^2 + 20x + 100$ models the crops in pounds per acre over x years.

The average rate of change can be calculated using formula

$\dfrac{f(b)-f(a)}{b-a}$

In your case,

$a=10\\ \\b=20,$

then

$f(a)=-10^2+20\cdot 10+100=-100+200+100=200\\ \\f(b)=-20^2+20\cdot 20+100=-400+400+100=100$

and the average rate of change is

$\dfrac{100-200}{20-10}=\dfrac{-100}{10}=-10$

This means the crop yield decreased by 10 pounds per acre (negative rate of change) from year 10 to year 20.
