D.
This is because it is a question that involves doing actual math rather than just asking and getting an answer.
        
                    
             
        
        
        
Answer:
amplitude=5
Step-by-step explanation:
y=a sin x
amplitude =|a|
here a=-5
|a|=5

Answer:
c.  22/24
Step-by-step explanation:
perimeter = 3/8 + 3/8 + 1/6 
perimeter = 22/24 or 11/12
 
        
             
        
        
        
Answer:
Parallel
Step-by-step explanation:
In the slope-intercept form (y=mx +c), the coefficient of x tells us the slope of the line.
2x +8y= 56
Let's rewrite this equation into the slope-intercept form.
8y= -2x +56
Dividing both sides by 8:


Slope= -¼
y= -¼x -5
Slope= -¼
Since both lines have the same slope, they are parallel to each other.
