The monetary value of a certain antique chair increases with its age (but at a diminishing rate). The rate of change in the value of the chair can be modeled as 2200 v(x) = x1.5 dollars per year where x years is the age of the chair, x 2 25. The chair was valued at $200 twenty-five years after it was crafted. (For the following questions, disregard inflation of the dollar.) (a) How much will the value of the antique increase between 25 and 100 years after it was crafted? How much will it be worth 100 years after it was crafted?

Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
