Bottled Water Sales The rate of U.S. sales of bottled water for the period 2007–2014 could be approximated by
a. Estimate the average annual sales of bottled water over the period 2007–2014, to the nearest 100 million gallons per year. [HINT: See Quick Example 2.]
b. Compute the 2-year moving average of s. (You need not simplify the answer.) [HINT: See Quick Example 3.]
c. Without simplifying the answer in part (b), say what kind of function the moving average is.

- Velocity of a Ball Thrown into the Air The position function of an object moving along a straight line is given by s = f(t). The average velocity of the object over the time interval [a, b] is the average rate of change of f over [a, b]; its (instantaneous) velocity at t = a is the rate of change of f at a. A ball is thrown straight up with an initial velocity of 128 ft/sec, so that its height (in feet) after t sec is given by s = f(t) = 128t - 16t². (a) What is the average velocity of the ball over the following time intervals? [3,4] [3, 3.5] [3, 3.1] ft/sec ft/sec ft/sec (b) What is the instantaneous velocity at time t = 3? ft/sec (c) What is the instantaneous velocity at time t = 7? ft/sec Is the ball rising or falling at this time? O rising falling (d) When will the ball hit the ground? t = sec Need Help? Read It Watch Itarrow_forwardpractice problem please help!arrow_forwardpractice problem please help!arrow_forward
