The roller coaster could be represented by the function for Choice D.
If you were to graph this function, you would find that the zeros (x-intercepts) of the function are at the points of -2 and 1. Those are the needed points in the problem.
Since this is a parabola that opens upward, the parabola must be below the axis (or support bar) between those values.
        
             
        
        
        
Here are the answers to the questions above:
1. Based on the list of fees above, the one that does not contribute to the <span>initial cost of leasing a car is the FINAL PAYMENT. Answer would be option B.
2. In leasing a car, the amount that does not affect the total cost is the PRINCIPAL CHARGE, and the answer for this is option A. 
Hope this helps.</span>
        
                    
             
        
        
        
Answer:
y<=5
Step-by-step explanation:
2-5y>=-23
subtract 2 from each side
-5y>=-25
divide both sides by -5
y<=5
 
        
             
        
        
        
X = 60° 
Because the square in the corner tells you that it is 90° (right angle)
So your equation to solve for x would be...
x + 30 = 90
Now you need to isolate the x.
Subtract both sides by 30. 
 x + 0 = 90 - 30
 x = 60
        
             
        
        
        
Answer:
x = ± 2i
Step-by-step explanation:
note that  = i
 = i
x² = - 12 ( take square root of both sides )
x = ±  = ±
 = ±  = ± 2i
 = ± 2i
