Answer:
The value of f(3) is -2.
Step-by-step explanation:
This is a recursive function. So

Now, we find f(2) in function of f(1). So


Now, with f(2), we can find the value of f(3).


The value of f(3) is -2.
Number of milk cartons put out for breakfast = 100
Number of cartons remaining at the end = 27
Number of cartons consumed = 100 - 27 = 73
Ratio of cartons remaining / cartons consumed = 27/73

To find the area you need to find the area of the triangle and multiply that by the height of the prism.
The area of the triangle is
.5*12*10 = 60
And the height is .5m = 50cm
So the area will be
60*50 = 3000
