Choice D
Step-by-step explanation:
The function will be continuous everywhere except where the function in the denominator is 0. We, therefore determine the value(s) of x for which the function will be 0;
Therefore, the points x= 2 and x =4 are points of discontinuity
Since there is no distance between the pole and the base of the tower, we can assume that the pole is at the base of the tower.
We can create a right triangles between the pole and its shadow and between the tower and its shadow as shown in the figure. Let
be the height of the tower. Since our triangles are similar the ratio between its sides is going to be proportional, so we can establish a proportion to find :
We can conclude that the tower is 137.27 meters tall.
