Answer:
+1+3
Step-by-step explanation:
1 +1=2
2+3=5
5+1=6
6+3=9
 
        
             
        
        
        
Percent means parts out of 100
140%=140/100=1.4
'of' means multiply 
'is' means =
140% of what is 48 means
1.4 times what=48
divide both sides by 1.4
what=34.285714285714285714285714...
        
                    
             
        
        
        
At a package weight of 8 they both cost $37
        
                    
             
        
        
        
What are the advantages of the parametric equations
Answer:
Step-by-step explanation:
Parametric equations shows the relation between a group of quantities by expressing the coordinates of points of a curve and function as one or more independent variables. 
From  the question given; the advantages of parametric equations  given 
x = 1 + 6 cos t 
y= -2 + 6 sin t
are
:
1) For a given value of the independent variable the parametric equation is used exactly one point on the graph
2) the parametric equations  have a finite domain
3) the parametric equation is easier to enter into a calculator for graphic
