Afarmer is tracking the amount of wheat his land is yielding each year. he finds that the function f(x) = −x2 + 20x + 75 models the crops in pounds per acre over x years. find and interpret the average rate of change from year 5 to year 15.

Average rate of change: 0

Interpretation: No increment in yield from year 5 to year 15.

Step-by-step explanation:

The function that models the yield is:

The average rate of change  of f(x) from x=a to x=b is given by the formula;

The average rate of change from year 5 to year 15 is:

Interpretation: There has not been any increment in yield from year 5 to year 15.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
