1. The number of acres in a landfill is given by the function B=9200E^-0.03t where t is measured in years. How many acres will the landfill have

1. The number of acres in a landfill is given by the function  B=9200E^-0.03t where t is measured in years. How many acres will the landfill have after 2 years? (Round to the nearest acre.)

2.On the day when Julie left for her vacation, the function that converted U.S. dollars to British pounds was f(x) = 0.53421x, where x is the number of U.S. dollars and f(x) is the number of British pounds. Find the inverse function.

3. Let f(x) = 3(1 - x). Find f(4).

4. If f(x) = 3x - 3 and g(x) = 4x2 + 14x + 3, evaluate(f/g) (-5).
