1. If a person's hair grows at .35 mm per day, what is this growth rate in te 1 mm (millimeters)= .1 cm (centimeters) 2.54 cm = 1 inch 12 inches = 1 foot 365 days in a year 100 years in a century 2. A hill with a 12% grade is one that rises 12 m vertically for every 100 m of distance in the horizontal direction. At what angle is the hill inclined about the horizontal? 3. The drawing shows a triple jump in checkers. If each square is 4 cm per side, what is the magnitude of the displacement vector after the jump? 4. An Australian emu is running due north in a straight line at a speed of 13.0 m/s and slows down to 10.6 m/s in 4.0 s. What is the direction of the bird's acceleration? Assuming the acceleration stays the same, what is the bird's velocity after another 2.0 s?

One student uses a meterstick to measure the thickness of a textbook and obtains 4.3 cm 0.1 cm. Other students measure the thickness with vernier calipers and obtain four different measurements: (a) 4.32 cm 0.01 cm. (b) 4.31 cm 0.01 cm, (c) 4.24 cm 0.01 cm, and (d) 4.43 cm 0.01 cm. Which of these four measurements, if any, agree with that obtained by the first student?

Q10. The height of a certain hill (in feet) is given by h(x, y) = 10(2xy- 3x2 - 4y² - 18x + 28y + 12), where y is the distance (in miles) north, x the distance east of South Hadley. How steep is the slope (in feet per mile) at a point 1 mile north and one mile east of South Hadley? In what direction is the slope steepest, at that point?
