Answer:
i dont know sorry
Step-by-step explanation:
P(5,2) = n! /(n-r)!
n = 5, r = 2:
= (5 x 4 x 3 x 2 x 1 ) / 3 x 2 x 1
Cancel out common factors:
= 5 x 4 = 20
The answer is 20.
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:
9
Step-by-step explanation:
If x is the number of 10-inch stones, then (x-1) is the number of 5-inch stones, and the total width is ...
10x +5(x-1) = 130
15x -5 = 130 . . . . . . . eliminate parentheses
15x = 135 . . . . . . add 5
x = 9 . . . . . . . divide by 15
Wesley will need 9 10-inch stones for one row.
