- Does a Limiting Value Occur? A rocket ship is flying away from Earth at a constant velocity, and it continues on its course indefinitely. Let D(t) denote its distance from Earth after t years of travel. Do you expect that D has a limiting value?arrow_forwardAlligator Teeth Researchers have developed a mathematical model that can be used to estimate the number of teeth N(t) at time t days of incubation for Alligator mississippiensis, where N(t)=71.8e8.96e0.0685t. Source: Journal of Theoretical Biology. a. Find N(65), the number of teeth of an alligator that hatched after 65 days. b. Find limtN(t) and use this value as an estimate of the number of teeth of newborn alligator. Hint: See Exercise 71. Does this estimate differ significantly from the estimate of part a?arrow_forwardUse a graphing calculator to answer the following questions. a. From a graph of y=xex, what do you think is the value of limxxex?Support this by evaluating the function for several large values of x. b. Repeat part a, this time using the graph of y=x2ex. c. Based on your results from parts a and b, what do you think is the value of limxxnex, where n is a positive integer?Support this by experimenting with other positive integer n.arrow_forward
- Find limx1(x2+2).arrow_forwardWhen Limiting Values Occur Suppose S(t) represents the average speed, in miles per hour, for a 100-mile trip that requires t hours. Explain why we expect S to have a limiting value.arrow_forwardUse your schools library, the Internet, or some other reference source to find real-life applications of approximations of functions.arrow_forward
