1. When an electric current passes through two resistors with resistance and , connected in parallel, the combined resistance, , can be calculated from the equation . Find the rate at which the combined resistance chances with respect to changes in . Assume that is constant.

2. A museum has decided to sell one of its paintings and invest the proceeds. If the picture is sold between the years 2000 and 2020 and the money from the sale is invested in a bank account earning 5% interest per year compounded annually, then , the balance in the year 2020, depends on the year, , in which the painting is sold and the sale price . If is measured from the year 2000 so that then .
