Answer:
cosA =
Step-by-step explanation:
cosA = = =
If they are decreasing at 3% , net = 100% - 3% = 97%
Reduction rate = 97% = 0.97
After 1st year = 1200*0.97
After 2nd year = 1200*(0.97)*(0.97) = 1200*(0.97)²
After 3rd year = 1200*(0.97)*(0.97)*(0.97) = 1200*(0.97)³
After x years, = 1200(0.97)ˣ
Therefore, function f(x) = <span>1200(0.97)ˣ</span>
