Answer:
B. Square root
Step-by-step explanation:
using distance formula:
x = √z^2 - y^2
y = √z^2 - x^2 
=> z = √x^2 + y^2
 
        
                    
             
        
        
        
Given:
The table represents a proportional relationship.
To find:
The equation of the function.
Solution:
If y is directly proportional to x, then

 ...(i)
     ...(i)
where, k is the constant of proportionality.
From the given table it is clear that the function passes through (2,1). So, the equation must be satisfied by the point (2,1).
Putting x=2 and y=1 in (i), we get


Putting  , we get
, we get

Therefore, the correct option is A.

Answer:
w = 
Step-by-step explanation:
Reverse the equation placing w on the left side
8w - 3 = - 12u + 13 ( add 3 to both sides )
8w = - 12u + 16 ( divide both sides by 8 )
w =
