Suppose that a fire truck is parked in front of a building as shown in the figure. The beacon light on top of the fire truck is located 13 feet from the wall and has a light on each side. If the beacon light rotates 1 revolution every 2 seconds, then a model for determining the distance d, in feet, that the beacon of light is from point A on the wall after t seconds is given by d(t) = |13 tan (xt)|. Complete parts (a) through (e) below. [tt= z k is an odd integer Explain what this means in terms of the beam of light on the wall. Choose the correct answer below. O A. When the function is undefined, the light is shining on every point on the wall. OB. When the function is undefined, the light is not shining completely on the wall. C. When the function is undefined, there is no light shining on the wall. D. When the function is undefined the beam of light is shining on exactly one point on the wall 13 ft A
