h(t) is the height of the diver in feet above the water
Now it asks about the time at which diver reaches the water
When diver reaches the water , the height of diver from water should be zero
So we plug h(t) =0
So

divide whole equation by -16

we can now factor the quadratic equation
So we get
(t+4)(t-3) =0
plug each factor equal to zero and solve for t
t+4 =0 and t-3 =0
So t=-4 and t=3 
Now time cannot be negative , So t=3 
So time = 3 seconds
It takes 3 seconds for the diver to reach the water
 
        
             
        
        
        
Answer:
x= -4
Step-by-step explanation:
 
        
             
        
        
        
-x+26=2x-10
+x +10  +x +10
36+3x
divde by 3
12=x
m∠D=2(12)-10
        =24-10
        =14
        
                    
             
        
        
        
Answer:
It's F
Step-by-step explanation:
You can see on the graph that 2 lines cross at (-3;4) so this is the point where the 2 equations have the same outcome/ value.
