Answer:
C. 2,150
Step-by-step explanation:
We know that out of 120 passengers, 86 were satisfied with the service. 
To find the percentage amount of passengers who were satisfied, we can divide 86 by 120 and get 0.716 repeating (about 71.6%). 
Then, we can multiply the total number of passengers, 3,000, by that number and get 2,150. 
 
        
             
        
        
        
Answer:
x^4 + 5x^3 - 12x^2 + 5x + 1
 
        
                    
             
        
        
        
1) in first place you need to Know what kind of figure is it, in order to find solve the problem, as you can see it is a parallelogram, and the condition for this geometric figure the opposites  are equal ,
2) if you have a non -rectangular parallelogram and draw a diagonal  from A to C, you obtain two equal triangles, for this reason the line AC IS CALLED DIAGONAL,  and divide the parallelogram
3) in first place to determine that the angles are congruents for two triangles the Diagonal is comun for both, and the vertex  ∡CAB IS THE SAME ∡ACD
4) If the diagonal AB AND CD are equal , AD AND BC are equal too, then the triangles are congruent
5)  segment AB Parallel to CD THEY HAVE THE SAME SLOPE AND MAGNITUDE
 
        
             
        
        
        
(t^2+1)^100
USE CHAIN RULE
Outside first (using power rule)
100*(t^2+1)^99 * derivative of the inside
100(t^2+1)^99 * d(t^2+1)
100(t^2+1)^99 * 2t
200t(t^2+1)^99
        
                    
             
        
        
        
The answer is 2.99 explanation is that I used my calculator lol
