So column A needs to all be the same multiples of 4 so 4•3 is 12 and so other multiples need to be placed
        
             
        
        
        
Answer:
Step-by-step explanation:
5. is hypothenuse because it is across from the right angle 
3. and 4. are legs
 
        
                    
             
        
        
        
Answer:
b
Step-by-step explanation:
Using the trigonometric identity
sin2x = 2sinxcosx
That is the angle on the right side is half the angle on the left, thus
sinΘ = 2sin( Θ )cos(
 Θ )cos( Θ ) → b
Θ ) → b
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Pythagorean Theorem: 
In this case, a = 9, b = a, and c = 15.


The, we subtract 81 from both sides getting:
 ,
,
Then, 
 
        
             
        
        
        
Answer:
The answer is B
Step-by-step explanation:
The reason why I say this is because if you plot both graphs on one cordinate plance, you can see that the difference between the two graphs is that the graph of f(x) HAS BEEN SHIFTED DOWN 6 UNITS.As a result, the correct answer choice is B.Hope that helped @user.
