Seasonal business cycle. Suppose that profits on the sale of swimming suits over a 2-year period are given approximately by
where P is profit (in hundreds of dollars) for a week of sales t weeks after January 1. The graph of the profit function is shown in the figure.
(A) Find the exact values of P(13), P(26), P(39), and P(52) without using a calculator.
(B) Use a calculator to find P(30) and P(100). Interpret the results.
(C) Use a graphing calculator to confirm the graph shown here for y = P(t).

The base of the cake tin has a characteristic dimension / and is illustrated in Figure 1 below, you should assume the top and bottom of the shape can be represented by semi-circles. The vertical sides of the cake tin have a height of h. As the company's resident mathematician, you need to find the values of r and h that minimise the internal surface area of the cake tin given that the volume of the tin is Vfixed- 2r Figure 1 - Plan view of the "ghost" cake tin base.
