Answer:
Hydrostatic Force = 35.28KN
Step-by-step explanation:
To solve this question, let's consider integrating the hydrostatic force from the top of the triangle to the bottom. 
Formula for a thin horizontal slice of the triangle the force is;
δF=ρgxwδx 
Where w is width of triangle; ρ is density of water and g is acceleration due to gravity 
At depth x, the width of the triangle is w=2/3x.
Thus, F = (3,0)∫)ρgxwδx
 =(2/3)ρg[(3,0)∫)x²δx] 
= integrating, we have;
F = (2/3)ρg[(3³/3) - (0³/3)] 
F = (2/5)ρg [27/3] = (2/5)(1000)(9.8)(9) = 35280 N = 35.28 KN
 
        
             
        
        
        
Answer:
24*3x
Step-by-step explanation:
x = the water park's admission
 
        
             
        
        
        
0.00000004 to the power of 4
Your answer would be <u>0</u>
 
        
                    
             
        
        
        
Expected value E(x) = 0.9994(150000 - 181) = 0.9994 x 149819 = $149,729.11
        
             
        
        
        
[(1515+1010) / 55] x 33 = 1515 
If you calculate separately for pink and red using above formula (909pink, 606red, which equals to the same 1515)
Hope that answers it for you..
