The number of bacteria in a refrigerated food product is given by N(T)=23T256T+1,3T33 ,where T is the temperature of the food. When the food is removed from the refrigerator, the temperature is given by T(t)=5t+1.5 , where t is the time in hours. a. Find the composite function N(T(t)) . b. Find the time (round to two decimal places) when the bacteria count reaches 6,752.
In this problem you are asked to find a function that models in real life situation and then use the model to answer questions about the guidelines on page 273 to help you. Minimizing Time A man stands at a point A on the bank of a straight river, 2 mi wide. To reach point B, 7 mi downstream on the opposite bank, he first rows his boat to point Pon the opposite bank and then walks the remaining distances x to B, as shown in the figure. He can row at a speed or 2 mi/h and walk as a speed of mi/h (a) Find a function that models the time needed for the trip. (b) Where should he land so that he reaches B as soon as possible?
Use your schools library, the Internet, or some other reference source to find real-life applications of approximations of functions.
If xis large, which function grows faster, f(x)=2x or g(x)=x2?
How can you determine whether a function is odd or even from the formula of the function?
How do the graphs of the functions f(x)=x2 and f(x)=x21 differ? We graphed them at the start of this section. What is the difference between their graphs? How are their graphs the same?
On a desert island lives a colony of extremely active dormouse. The population are given by time t (in months after 1. jan, 2020) is given by the function: a) During a calendar year; when is the population the largest and when is it the smallest? When is the population is strictly growing and when is it strictly declining?
Consider the following problem. A bicyclist is riding on a path modeled by the function f(x) = 0.05(8x – x2), where x and f(x) are measured in miles. Find the rate of change of elevation when x = 2. (Round your answer to two decimal places.) Decide whether the problem can be solved using precalculus, or whether calculus is required. If the problem can be solved using precalculus, solve it. If the problem seems to require calculus, use a graphical or numerical approach to estimate the solution.
