Hooke’s law The distance d between the bottom of a suspended spring and a countertop is a linear function of a weight w attached to the bottom of the spring. The bottom of the spring is 9 inches from the countertop when the attached weight is 1.5 pounds and 5 inches from the countertop when the attached weight is 2.5 pounds. Find a linear model that relates the distance d from the countertop and the weight w . Find the distance between the bottom of the spring and the countertop is no weight is attached. What is the smallest weight that will make the bottom of the spring reach the countertop? (Ignore the thickness of the weight.)

In the integral dxf1dy (7)², make the change of variables x = ½(r− s), y = ½(r + s), and
evaluate the integral. Hint: Find the limits on r and s by sketching the area of integration in the (x, y) plane along
with the r and s axes, and then show that the same area can be covered by s from 0 to r and r from 0 to 1.
