Answer:  
 
Step-by-step explanation:
The constant of proportionality 'k' between two variables ( one independent and one dependent ) is given by :-
 
In the given table, independent variable = Days
Dependent variable = Total Miles
From first row,  Days = 3
Total Miles = 
Then, the constant of proportionality in the table

Hence, the constant of proportionality in the table is 
 .
 
        
             
        
        
        
1 + 1 = 2
2 + 2 = 4
4 + 3 = 7
7 + 4 = 11
11 + 5 = 16
16 + 6 = 22
22 + 7 = 29
29 + 8 = 37
sorry that I do not know the equation for this problem...but ur next 3 numbers are : 22,29,37.....so ur answer is D

Step-by-step explanation:
 
        
             
        
        
        
The equation 
  in standard form looks like 
.
Given equation of sphere be 
.
We are required to express the given equation in the standard form of the equation of sphere.
Equation is basically relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It may be linear equation,quadratic equation, cubic equation or many more depending on the powers of variables. The standard form of the equation of sphere looks like  
.
The given equation is 
.
We have to break 22 which is in right side into various parts according to the left side of the equation.





Hence the equation 
  in standard form looks like 
.
