pre: 0 of 1 pt 14 of 19 (13 complete) HW Score: 68.42%, 13 5.87-LS Question Help The median weight of a boy whose age is between 0 and 36 months can be approximated by the function w(t) = 8.53 +1.871 -0.00692 +0.00052913 where tis measured in months and wis measured in pounds. Use this approximation to find the following for a boy with median weight in parts a) through c) below. a) The rate of change of weight with...
The time between infection and the display of symptoms for streptococcal sore throat is a random variable whose probability density function can be approximated by 1 p(t) -te-0.05 15,676 for t > 0 (where t is measured in hours). (a) Set up an integral that gives the probability that an infected patient will not display symptoms until after 36 hours. (b) Use a computer algebra system (such as Wolfram Alpha) to approximate the integral from part (a). (c) Using your...
The average speed of a vehicle on a stretch of Route 134 between 6 A.M. and 10 A.M. on a typical weekday is approximated by the function f(t) = 13t − 26 t + 36 (0 ≤ t ≤ 4) where f (t) is measured in miles per hour, and t is measured in hours, with t = 0 corresponding to 6 A.M. At what time of the morning commute is the traffic moving at the slowest rate? A.M. What...

11. (10pts) According to data from the Cellular Telecommunication Industry Association, the rate of increase in the number of cell phone subscribers (in mullions) since 2000 is approximated by, S'(x) = 1.46x + 2.66, where x = 0 corresponds to 2000. There were 158.7 million subscribers in 2013. Find a function S(x) that gives the number of subscribers (in millions) in year x. 13. (10pts) The rate of change of the population of a rare species of Australian spider is...
A toxic radioactive substance with a density of 8 milligrams per square centimeter is detected in the ventilating ducts of a nuclear processing building that was used 35 years ago. The density of the radioactive substance when it was deposited 35 years ago was approximately _ mg/cm Between 2005 and 2009, the average rate of inflation was about 2.8% per year. If a cart of groceries cost $180 in 2005, what did it cost in 2009? A cart of groceries...

Problem 36 bclow presents a model describing the drag of a fluid medium that is released from rest at time t 0 (same initial conditions). Using Newton's Second Law, you build a model of the form particle moving through a (governing equation (initial velocity) mi mg-F drag '0 (0)(0)a (t) is the particle's position, m is the mass of the particle, g is the acceleration due to gravity, and Fa is the magnitude of the drag force. You account for...
