Average rate of change is 0

Interpretation: The crop yield did not change from year 5 to year 15

<em><u>Solution:</u></em>

The function that models the yield is:

f(x) = -x^2 + 20x + 75

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

\text{ average rate of change }=\frac{f(b)-f(a)}{b-a}

Find and interpret the average rate of change from year 5 to year 15

f(5) = -(5)^2 + 20(5) + 75\\\\f(5) = -25 + 100 + 75\\\\f(5) = 150

f(15) = - (15)^2 + 20(15) + 75\\\\f(15) = -225 + 300 + 75\\\\f(15) = 150

<em><u>Thus average rate of change:</u></em>

\text {average rate of change}=\frac{f(15)-f(5)}{15-5}

\text {average rate of change}=\frac{150-150}{10}=0

Thus Average rate of change is 0

Interpretation: The crop yield did not change from year 5 to year 15.

The sum of 86, 68, and 38 is 192. What do you also know about the sum of 68, 38, and 86? Explain
trasher [3.6K]
It's the same because it's used the commutative property where:

a+b = b+a

So, 86+68+38=192 it's the same sum as 68+38+86=192

Isabella bought 4 1/4 pounds of watermelon for $14.88. What is the price, in dollars, of 1 lb of watermelon?
Harman [31]

Answer: The correct answer is $ 3.50 per pound. If she buys 4 1/4 pound, we convert the 1/4 to the decimal 0.25. Take the total cost of $14.88 and divide it by 4.25, the amount of watermelon she bought and it equals $3.50 per pound.

14.88/4.25= 3.50
