Answer:
   445.10 feet
Step-by-step explanation:
The relation between angle of depression and distance to the boat is ...
   Tan = Opposite/Adjacent
   tan(angle of depression) = (200 ft)/(distance to boat)
Then the distance to the boat is ...
   distance to boat = (200 ft)/tan(angle of depression)
__
We want the change in distance between the two angles, so ...
   change in distance = (200 ft)/tan(17°31') -(200 ft)/tan(46°41')
   = (200 ft)(cot(17°31') -cot(46°41'))
   change in distance ≈ 445.10 ft
 
        
             
        
        
        
You can find any ordered pair in which the y coordinate is 4 times the x coordinate.
For example, an ordered pair could be (2,8) or (5,20)
        
             
        
        
        
The answer should be 3x-1 depending on if thats 3x^2 or 3*2 but im guessing its 3 times 2 so your answer should me 3x-1
 
        
             
        
        
        
Answer:
The given expression is equivalent to -x
That is 
Now Verified that the two expressions are equivalent
Step-by-step explanation:
Given that Genevieve wants to verify that One-fifth (5 x minus 20) minus one-half (4 x minus 8) is equivalent to Negative x
It can be written as below :

Now we can verify the expression is equivalent or not :
Taking  LHS

 ( by using the distributive property )
 ( by using the distributive property )

 ( adding the like terms )
  ( adding the like terms )
 =RHS
=RHS
Therefore LHS=RHS
Therefore the given expression is equivalent to -x
That is 
Now Verified that the two expressions are equivalent
