Answer:
4(x -  )² = 0
 )² = 0
Step-by-step explanation:
Given
4x² - 4x + 1 = 0
To complete the square the coefficient of the x² term must be 1
Factor out 4 from 4x² - 4x
= 4(x² - x) + 1 = 0
add/subtract ( half the coefficient of the x- term )² to x² - x
 4(x² + 2(-  )x +
 )x +  -
 -  ) + 1 = 0
 ) + 1 = 0
 4(x -  )² - 1 + 1 = 0
 )² - 1 + 1 = 0
4(x -  )² = 0
 )² = 0
 
        
                    
             
        
        
        
Derivitive of cosx=-sinx
dy/dx sinx=cosx
and use chain rue
2cosx=-2sinx
2cos2x=-4sin2x
so
-2sinx-4sin2x id the deritivitve
        
             
        
        
        
The trick question is that you can’t effect an unknown value because you don’t know what number it is, it has to be a known value, there is nothing that you can do to figure it out, so it’s unknown and cannot be effected.
        
             
        
        
        
Answer:
$146410
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value  
P = Present value  
R = interest rate  
N = number of years 
100,000 x (1.1)^4 = $146410
