General form of vertex of a parabola is
y  = a(x - b)^2 + c     where vertex  = (b , c)
for this equation the vertex is at (-1,0).
the axis of symmetry  is  x = -1
        
             
        
        
        
Answer:
-6
Step-by-step explanation:
(y2-y1) / (x2-x1)
(-16-(-10)) / (2-1)
(-6) / (1)
= -6
Take any two points in the graph and put them into the formula.
 
        
                    
             
        
        
        
Answer:
0.0772
Step-by-step explanation:
P(Power) + P(Type II Error) = 1, so P(Type II Error) = 1 – P(Power) = 1 – 0.9228 = 0.0772.
 
        
             
        
        
        
1 gallon = 8 pints. 1 quart = 2 pints. 
1 gallon 2 quarts 3 pints of orange juice = 15 pints
1 gallon 3 quarts 7 pints of pineapple juice = 21 pints
1 gallon 3 quarts 3 pints of ginger ale = 17 pints.
Total in pints: 53
Total = 6 gallon 2 quarts 1 pint.
        
                    
             
        
        
        
Answer:
C
Step-by-step explanation:
There’s nothing hard with this
You need to know special right triangles
This is a 30,60, 90 triangle
We automatically know becuase theres. Right angle (90) and a 60 degree angle
now the formula is the smallest side is (n) {I’m using N becuase theres already an X) or in this case, 6
The hypotenuse, the one directly above the 2nd biggest side, or the diagnoal side is 2n or (12). Now we know what X is in this situation which is 12. So that narrows it to 2 answers 
Now the side on the bottom of the hypotenuse, the second biggest side is used in the formula N . So we know what N is in the beginning, 6 so we just plug that in and well get C. Attached is a photo on q 30, 60, 90 special right triangle
