Answer:
7
Step-by-step explanation:
The average rate of change of f(x) in the close interval [ a, b ] is
Here [ a, b ] = [2, 5 ]
f(b) = f(5) = 2(5)² - 7(5) = 50 - 35 = 15
f(a) = f(2) = 2(2)² - 7(2) = 8 - 14 = - 6, thus
average rate of change = 
= 
= 7
Answer:
k=20.
Explanation: First we find where f(x) has its local extrema: f'(x)=3x2−10x+3. The critical points are roots of the equation: 3x2−10x+3=0.
Answer:
1. 75
2. 1
Step-by-step explanation:
Answer: The cost of goods sold= 5881.75
Step-by-step explanation:
Cost of available goods = 75x32.97 + 75x33.78 + 150x35.02= $10259.25
Units available= 150 + 75 + 75= 300
Sold units= 175
Ending inventory= 300-175=125
Value of ending inventory= 125x35.02= $4377.5
Cost of goods sold= cost of available goods – value of ending inventory
Cost of goods sold= 10259.25 – 4377.5= $5881.75
