This is a parabola that opens downward.
Remember that the axis of symmetry is located at x=-b/(2a).
So the vertex is at (3,-1)
So functions slope is positive or increasing on (-co, 3] and decreasing on [3,co).
        
                    
             
        
        
        
Answer:
100 minutes cost Todd $24. He had extra bill of 26.38 - 24 = $2.38
$2.38 = 238 cents
7 cents billed for 1 extra minute
1 cents billed for 1/7 extra minute
238 cents billed for 238/7 = 34 extra minutes
total minutes = 134 minutes
 
        
             
        
        
        
(4x^4-1)÷x+1
(256x-1)÷x+1
256-1+1
256
The first step shows the problem
The second step powers 4x 4 times
The third step removes x
The 4th step shows the problem after x is removed.
The 5th step is the answer: 256
 
        
             
        
        
        
Answer:
3/40
Step-by-step explanation:
Multiply 1/5 * 3/8
 
        
             
        
        
        
 Based on the setup costs, the steady annual demand, and the costs to store, the number of cases to produce to minimize cost is 528 units .
<h3>How many cases should be produced to minimize cost?</h3>
This can be found by using the Economic Order Quantity.
= √ ( (2 x Setup costs x annual demand) / holding costs for the year)
Solving gives:
= √ ( ( 2 x 33 x 38,016) / 9)
= √278,784
= 528 units
