Answer:
The answer to your question are letters A, C and D.
Step-by-step explanation:
To factor this polynomial we need to look for the common factor of the three terms.
To find it, get the greatest common factor
                         140    28   14     2
                           70    14     7     2
                           35     7     7     5
                             7     7      7     7
                              1     1       1     
Greatest common factor = 2 x 7 = 14  
Factor the polynomial
 140c + 28 - 14a = 14 ( 10c + 2 - a)
Factor only 7          7(20c + 4 - 2a)
Factor only 2          2 (70c + 14 - 7a)
 
        
             
        
        
        
To answer this item, we take the differential of the equation and equate to zero.
 
                  C(x) = 0.8x² - 256x + 25939
Differentiation,
                dC(x) = 1.6x - 256 
                 dC(x) = 1.6x - 256 = 0
The value of x from the derived equation above is 160. 
Thus, the number of machine to be made in order to minimize the cost should be 160. 
        
                    
             
        
        
        
For this case we have that by definition, the circumference of a circle is given by:

Where:
d: It is the diameter of the circle
They tell us that:

Substituting:

Thus, the circumference of the circle is 55 centimeters.

Basically, the equator is like the x-axis of the world and the prime meridian is like the y-axis. You locate places by distances from these lines.
