The tangential line at a certain point is just the derivative so.

. At the point (1,6) we plug the x value in and get the slope at the point (y ' = 2)
The tangential line at that point is 
y - 6 = 2(x - 1)     (this is the answer)
 
        
             
        
        
        
5x7-3x8+11
35-24+11
11+11
The answer is 22
        
                    
             
        
        
        
I would answer the problem but first upload the diagram 
        
             
        
        
        
It won't. Both are increasing by 1.5 every year. If you graph that, the lines will be parallel. Parallel lines have no intercept.
        
             
        
        
        
Answer: 52.9 quarts
Step-by-step explanation:
From the question, we are informed to calculate the number of quarts that are in 50 liters.
1 liter = 1.057 liquid quarts
50 liters will now be:
= 50 × 1.057
= 52.85
= 52.9 quarts
