A farmer is tracking the amount of corn his land is yielding each year. He finds that the function f(x) = −x2 + 20x + 50 models

zysi [14]

Answer:

The crop yield decreased by 0.09 pounds per acre from year 1 to year 10

Step-by-step explanation:

The function that models the crops in pounds per acre over x years is

$f(x)=-x^2+20x+50$

In year 1, the crop yield is $f(1)=-(1)^2+20(1)+50=69$

In year 10, the crop yield is $f(10)=-(10)^2+20(10)+50=150$

The average rate of change from year 1 to year 10 is given by:

$\frac{f(10)-f(1)}{10-1}$

We substitute the values to get:

$\frac{150-69}{10-1}$

$=\frac{81}{9}=9$

Since the average rate of change is positive, the crop yield decreased by 0.09 pounds per acre from year 1 to year 10.
