Answer:

Step-by-step explanation:

Let us first find the hypotenuses of the right triangle.

c=\sqrt{12^2+9^2} =\sqrt{225} = 15

sin(theta) = 12/15 = 4/5\\cos(theta) = 9/15 = 3/5\\tan(theta) = 12/9 = 4/3\\csc(theta) = sin(theta)^{-1}  = 5/4\\sec(theta) = cos(theta)^{-1} = 5/3\\cot(theta) = tan(theta)^{-1} = 3/4

The answer is a decreasing exponential function because the percentage of change is constant. You can obtain this answer by looking at the amount of decrease each time and dividing it by the higher value. If you do this for each step, you'll see that there is a 12% decrease for each year.
