Answer:
A=3, B=4, C=-5
Step-by-step explanation:
So A represents the amplitude, which is the distance between the midline (C), the middle of the graph, and the maximum (or minimum). B is the distance of the period of the graph. In this case, we see that the midline is C=-5 because that is the halfway point of the sine function. We also see that the period distance is B=5-1=4, so our period would be 2π/4 or π/2. Our amplitude would be A=3 because |a|=|-5-(-2)|=|-5+2|=|-3|=3. Observe the graph to see this visually.
 
        
             
        
        
        
Answer:
 Option D is the correct answer.
Explanation:
  A girl has 3 different swimsuits, 4 different shorts and 3 different pairs of flip-flops.
  Different ways can this girl wear a swimsuit, a pair of short and a pair of flip-flops = 3P₁ x 4P₁ x 3P₁
                = 3 x 4 x 3
                = 36
   Different ways can this girl wear a swimsuit, a pair of short and a pair of flip-flops = 36
 Option D is the correct answer.
 
        
             
        
        
        
Answer:
the second one
Step-by-step explanation:
 
        
                    
             
        
        
        
18.5-0.5= 18
18/3= 6
So r=6
