3. Suppose that the temperature on a metal plate is given by the function T with T(x, y) = 100 - (x² +4y²) where the temperature is measured in degrees Fahrenheit and a and y are each measured in feet. Now suppose that an ant is walking on the metal plate in such a way that it walks in a straight line from the point (1, 4) to the point (5, 6). (a) Find parametric equations for the ant's a and y coordinates as it walks the line from (1,4) to (5,6) in one minute at a constant speed. (b) What can you say about dr dt and dy dt for every value of t? (c) Determine the instantaneous rate of change in temperature with respect to t that the ant is experi- encing at the moment it is halfway from (1, 4) to (5,6). Include units in your answer.
A function has only one relative minimum at (-5, -1). Which of the following could have been the test results that confirmed this? Select one alternative: f'(-5) = 0, and f'(-6)=1 and f'(0) = 32 O f'(-5) = 0, and f'(-6) = 1 and f'(0) = 12 f'(-5) = 0, and f'(-6)=-4 and f'(0) = 1 f'(-5) = 0, and f'(-6)= -1 and f'(0) = -2
Suppose (-8, 6) is a critical point of a function f with continuous second derivatives. If fræ (-8, 6) = 9, fæy (–8, 6) = 9 and fyy (–8, 6) = –1, use the Second Derivatives Test to classify the point (-8, 6).
The stock price for a certain corporation can be approximated for the years 2012 through 2017 by f(x)% 3D6.3x- 168x+ 1199, where x = 12 corresponds to the year 2012. During what year did a local minimum stock price occur? A local extremum occurs at a critical number of f. Because the derivative exists for every x, the only critical number(s) occur where the derivative is zero. Find the derivative of f(x). f'(x) =
