A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, t

If we let
x as the distance traveled by the boat
y as the distance between the boat and the lighthouse.

Then, we have:
tan 18°33' = 200 / (x + y)
and
tan 51°33' = 200 / y

Solving for y in the second equation:
y = 200 / tan 51°33'

Rearranging the first equation and substituting y
x = 200 / tan 18°33' - 200 / tan 55°33'
x = 458.81 ft

Therefore, the boat traveled 458.81 ft before it stopped.

2*cosx*(2x+30°) + √3=0

MAXImum [283]

Answer: x ≈ 1.59688927, −1.60312387, −4.67045686, 4.69039614, 7.872914, −7.91513776, −10.89002194

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable.

Simplify 2*cosx*(2x+30°) + √3=0

Simplify each term.

Apply the distributive property.

2 cos ( x ) ( 2 x ) + 2 cos ( x ) * 30 ° + √ 3 = 0
Multiply 2 by 2
4 cos ( x ) x + 2 cos ( x ) *30 ° + √ 3 = 0
Multiply 30 °by 2
4 cos ( x ) x + 60 cos ( x ) + √ 3 = 0
Reorder factors in 4 cos ( x ) x + 60 cos ( x ) + √3
4xcos(x)+60cos(x)+√3=0
Graph each side of the equation. The solution is the x-value of the point of intersection. x ≈ 1.59688927 , − 1.60312387 , − 4.67045686 , 4.69039614 , 7.872914 , − 7.91513776 , − 10.89002194
