Answer:
Cannot be solved.
Step-by-step explanation:
There is know equation what so ever that you are referring to.
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:

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

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


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


Thus Average rate of change is 0
Interpretation: The crop yield did not change from year 5 to year 15.
Answer:
1. D 2. B 3. C
Step-by-step explanation:
WARNING: I am not 100% sure about 2.
1. If you simplify the first part of the equation for letter D, you'll realise it is the same equation.
2. It is either B or D. I believe it is B because you would not have to multiply 4 again.
3. The square root of 121 is eleven, the square root of x^2 is x. x=11.
Find the length of the circumference:
Circumference = 2 x pi x radius
Circumference = 2 x 3.14 x 7
Circumference = 43.96 kilometers
90 degrees is 1/4 of a circle ( 360/4 = 90)
Arc length = 43.96/4 = 10.99 kilometers
