Answer:
x≤-3      2 ≤x<7  
Step-by-step explanation:
(x^2+x-6) /(x-7) ≤0
Factor the numerator
(x+3)(x-2) / (x-7)≤0
Critical points are
X =-3  X =2  X=7
We need to check the values when
x≤3  -3 ≤ x≤2           2 ≤x<7   x>7  
(x cannot be 7 because then the denominator is zero)
and see when it is less than 0
Substitute a value in and see if factor is positive or negative
x≤-3 
(negative)(negative) / (negative) =   negative 
 -3 ≤x≤2    
(positive)(negative) / (negative) = positive  this range does not work
       2 ≤x<7  
(positive)(positive) / (negative) = negative
 x>7
(positive)(positive) / (positive)
 
        
                    
             
        
        
        
Answer:
h = 54 feet
Step-by-step explanation:
The equation for the volume of a cone is V =  × π × r² × h.
 × π × r² × h. 
You have the volume, which is 8,138.88, and the radius of the base, which is 12. 
V = 8,138.88
h = 12
π = 3.14
When you plug everything you know into the equation, you get:
V =  × 3.14 × r² × h.
 × 3.14 × r² × h. 
8,138.88 =  × 3.14 × (12)² × h
 × 3.14 × (12)² × h
After you multiply everything on the right side, you come out with:
8,138.88 = 150.72 × h
To find h, you can divide each side by 150.72. 
8,138.88 ÷ 150.72 = 54 feet!
