Chapter 8.5, Problem 2QQ

An object moves along a straight line and it's velocity (v) in ms¹ at time (t) in seconds, is given by (2 ≤ t ≤7) V= 5-4t 3 Find the change in the displacement of the object from time t=2 to time t=7 Change in displacement = m

The immigration to the United States from Europe, as a percent of the total immigration, is approximated by the equation below where t is measured in decades, with t = 0 corresponding to the decade of the 1950s. P(t)=0.767t3-0.63t2-21.37t+51 (0 < t < 4)  (note- it is a line under both signs < I was able to type it) a) Complete the table.
