Answer:
5/12
Step-by-step explanation:
convert 1/3 to 4/12 and 1/4 to 3/12 so 3+4=7 so 7/12 dropped out so now 12-7=5 so 5/12 is the answer
 
        
                    
             
        
        
        
0.85 is between 0.8 and 0.9
        
                    
             
        
        
        
6 ft into meters would be 1.829, rounding to to nearest tenth would be 1.8
        
             
        
        
        
Part A
We have 

. To solve for the x-intercept, we set f(x) equal to 0.  That is     
 
     
Take the square root of both sides,      
 
      The x-intercept is (-2,0)
The x-intercept is (-2,0). 
To solve for the y-intercept, we set x=0. That is      
 The y-intercept is (0, 8)
The y-intercept is (0, 8) 
The coordinates of the optimum point are actually the vertex which can be easily seen from the vertex form equation given above. The minimum point is 
(-3, -1).
Part B.
We have 

.
Factor out -2     

Complete the square     

Simplify     

Part C
We have 

.
The maximum height is 12.25 feet after 0.875 seconds from the time of the jump. The dolphin will be back in the water after 1.75 seconds. The graph of the jump is shown in the photo.
