Jack looks at a clock tower from a distance and determines that the angle of elevation of the top of the tower is 40°. John, who
is standing 20 meters from Jack as shown in the diagram, determines that the angle of elevation to the top of the tower is 60°. If Jack's and John's eyes are 1.5 meters from the ground and the distance from Jack's eyes to the top of the tower is 50.64 meters, how far is John from the base of the tower? Round your answer to the nearest tenth.

Option B: 4 is the multiplicative rate of change of the function
Explanation:
The exponential growth function is
We need to determine the multiplicative rate of change of the function.
First, let us determine the values of function.
x y
1 8
2 32
3 128
4 512
Since, the multiplicative rate of change of an exponential function is the number by which the next term is increasing or decreasing.
Thus, the multiplicative rate of change of the function is given by
Multiplicative rate of change of the function =
Multiplicative rate of change of the function =
Multiplicative rate of change of the function =
Thus, the multiplicative rate of change of the function is 4
Therefore, Option B is the correct answer.
