Answer:

Step-by-step explanation:
The above question is in the form of an exponential decay. The equation for an exponential decay is given by:

where y and x are variables, b < 1, a is the initial value of y (that is the value of y when x = 0).
Let y represent the number of trees left and x represent the number of months. Given that there is currently 2.5 billion trees, therefore a = 2.5 * 10⁹, b = 0.5% = 0.005. The equations becomes:

Answer:
Sin = -5/13
Cos = 12/13
Tan = -5/12
Step-by-step explanation:
The mean absolute deviation shows the average distance number data is from each other. The bigger it is the farther the numbers are away from each other and vice versa.
