Answer:
The standard form of the equation for the conic section represented by  is:
 is:

Step-by-step explanation:
We know that:
 is the standard equation for an up-down facing Parabola with vertex at (h, k), and focal length |p|.
 is the standard equation for an up-down facing Parabola with vertex at (h, k), and focal length |p|.
Given the equation

Rewriting the equation in the standard form

Thus, 
The vertex (h, k) = (-5, 12)
Please also check the attached graph.
Therefore, the standard form of the equation for the conic section represented by  is:
 is:

where 
vertex (h, k) = (-5, 12)
 
        
             
        
        
        
The mean - add all the numbers (data) divided by the amount. 4+3+1+1+2+4+1 =16 16/7 = 2.28
The median - the middle number.
The mode - the most common number.
        
             
        
        
        
3x^2+12x+15=0
Then divide by 3 to get the x by itself. 
x^2+4x+5=0
Factor to (x+5) (x-1) and solve for the two values of x.
        
                    
             
        
        
        
Answer:
yes
Step-by-step explanation:
2 sqrt(3) * sqrt(12)
Rewriting sqrt(12) as sqrt(4 *3)
We know that sqrt(ab) = sqrt(a) sqrt(b)
sqrt(12) = sqrt(4) sqrt(3) = 2 sqrt(3)
2 sqrt(3) * sqrt(12) = 2 sqrt(3) * 2 sqrt(3)
                               =4 * (sqrt(3) )^3
                               = 4 *3
                                =12
