Question

A droid positioned on the ground 414 m from the base of the CN tower shines a laser beam at the top of the tower; 552m above the ground. The intensity of the beam as a function of distance x in meters from the droid is given by: I(x) = 2 ^−x/60

a) Find length of the beam.

b) Find sin θ, cos θ, and tan θ where θ is the angle between the laser beam and the ground.

c) Determine the angle θ in degrees and radians.

d) Determine the intensity of the beam at a distance of x = 120 meters. e) At what distance will the intensity be 0.125?

f) Use a diagram (sketch) to show the droid, the tower, the distances, and the angle
