All you have to do is multiply 18.3 x 5.1
18.3×5.1=93.33
It will take 93.33 minutes to repair the entire section. Hope that helps!
 
        
                    
             
        
        
        
Answer:
D: Sqrt 13
Step-by-step explanation:
I just did it on edg. 2020
 
        
                    
             
        
        
        
slope is change in y over change in x
 use 2 points from the table so -3,-21 and -6,-39
change in Y: -39 - -21 = -18
change in x = -6 - -3 = -3
slope = -18/-3 = 6
slope = 6
 
        
             
        
        
        
Answer:
C
Step-by-step explanation:
The red graph is the graph of y = f(x) shifted 1 unit right and then reflected in the x- axis.
Given y = f(x) then f(x + a) is a horizontal translation of a units
• If a > 0 then shift to the left of a units
• If a < 0 then shift to the right of a units
Here shift to the right of 1 unit, thus
y = f(x - 1)
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
Note the y- coordinates are the negative of each other, thus
- y = f(x)
Now  = - y, hence
 = - y, hence
The equation for the red graph is
 = f(x - 1) → C
 = f(x - 1) → C
 
        
             
        
        
        
5.2+4.8= 10
So it has to be 20 I think
