The tangent of the angle gives the ratio of the height of the lighthouse to the boat's distance
.. tan(angle of depression) = (lighthouse height)/(boat distance)
Then the distance to the boat is
.. boat distance = (lighthouse height)/tan(angle of depression)
We want to find the difference between two distances, so
.. boat travel = (lighthouse height)*(1/tan(first angle) -1/(tan(second angle))
.. = (200 ft)*(1/tan(17°31') -1/tan(46°41'))
.. ≈ 445.10 ft
Answer:
w^2 + 5w = 300
Step-by-step explanation:
A= length x width
A =300
Width = w
length = w + 5
Therefore
300 = (w) x (w + 5)
300 = w^2 + 5w
w^2 + 5w = 300
Answer:
Step-by-step explanation:
700,000 + 20,000 + 80
there are no exponents

Answer: f(0)=-1
Step-by-step explanation:
f(0) is a fancy way of saying the y value of the equation. the f(0) means that x=0. If you look at x=0, the graph is at y=-1. Therefore, f(0)=-1.
