Answer:
Step-by-step explanation:
<u>Consider the parent function:</u>
The graph of the function open up and the vertex is at the origin, the point (0, 0)
Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:
The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:
<u>Since all the options have 1/20 as a coefficient, our function is:</u>
This is option B
 
        
             
        
        
        
= 2ab + 4a + 6 - 6
= 2ab + 4a
you can factor this  to 2a(b + 2)
        
                    
             
        
        
        
The answer should be A. 4.5
Because line x is just over half of the length of the line that is 8ft
        
             
        
        
        
Let angle = x
sinx = 43.2/72.5
=> x = 36.57 degrees
