Answer:
29.7°
Step-by-step explanation:
In a right triangle representing the geometry of the problem, the side opposite the angle is the height of your observation (400 ft). The side adjacent to the angle is the distance from shore (700 ft).
You know the tangent ratio is ...
Tan = Opposite/Adjacent
so your angle of depression satisfies ...
tan(angle of depression) = (400 ft)/(700 ft)
Using the inverse function, we find ...
angle of depression = arctan(4/7) ≈ 29.745°
The angle of depression is about 29.7°.
Answer:
Domain = all real numbers
Range = {-1 [greater than or equal to] y [greater than] Infinity}
Move (-5)^-6 to the numerator
Multiply (-5)^5 and (-5)^-6 by adding the exponents and you would get (-5)^11
Then raise -5 to the 11th power and you would get −48828125
