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