This is the concept of scale factor. The linear scale factor is given by:
(height of sculpture)/(height of clothespin)
=20/(5/12)
=48
Given that a woman is 5ft 7 in, the sculpture of this woman would be:
height of sculpture=(scale factor)*(height of the woman)
height of the woman=5 ft 7 inches=5 7/12 ft=67/12 ft
hence the height of the sculpture will be:
67/12×48
=268 ft
Answer: 268 ft
        
                    
             
        
        
        
Answer:
294 square units
Step-by-step explanation:
35^2-21^2=a^2
a^2=784
square root 784=28
21*28/2=294
Answer=294

Answer:
There are many. Two examples are 

Step-by-step explanation:
There are many examples. The simplest is 
1 - 

It is trivial that 

2 - 

That function is injective as well. 

An example of a function that is NOT injective is 

Notice that
