Answer:
50 
Step-by-step explanation:
take the arc degrees (100) and divide by 2 
Inscribed angles are 1/2 of the created arc degrees 
 
        
                    
             
        
        
        
Answer:
8/9
Step-by-step explanation:
10-2/10-1=8/9
slope=8/9
 
        
                    
             
        
        
        
You will need three roots for this, so we have
 Let x = -30, -10 and +20
So the factors will be  (x+30)(x+10)(x-20)
The divide it to 100, this will help bring the peak up and down
So the polynomial function R(x) will become
1/100 *  (x+30)(x+10)(x-20)
R(x) = 1/100 * (x+30)(x+10)(x-20)
 
Finding the X-intercept:
Let R(x) = 0 and solve for x.
1/100 * (x+30)(x+10)(x-20) = 0
x = -30, -10, 20 are the x-intercepts.
