Answer:
B
Step-by-step explanation:
I think the answer is B but I could be wrong! I'm 98% confident in my answer though! 
 
        
                    
             
        
        
        
The curve has been attached and the answer choices are:
y = 3x² – 2x + 1
y = 3x² – 6x + 3
y = 3x²<span> – 7x + 1
</span>
The attached graph has a vertex in the first quadrant. Therefore, the coordinates of the vertex would be both positive.
Let's start with first equation:
                                               y = 3x² – 2x + 1
using the equation of axis:
                                            x = -b/2a
                                            x = 2/6                                            
x = 1/3
SUbstituting the value of x in the main equation to get the y-coordinate of the vertex.
                                               y = 3(1/3)² – 2(1/3) + 1
                                               y = 3/9 – 2/3 + 1
                                               y = 1/3 – 2/3 + 1
                                               y = (1 - 2 + 3)/3                                               
y = 2/3
Hence, the vertex would be:
                                             (h,k) = (1/3 , 2/3)
Also, the leading coefficient is positive, so the parabola would be concave up.
Thus the final answer choice will be:                                             
y = 3x² – 2x + 1

Answer:
51.41 g
Step-by-step explanation:
70.61 - 19.2 = 51.41
u minus the amount he poured already from the total
to find how much more he had to pour
51.41 + 19.2 = 70.61
