Poll Participation Make-up Assignments

Note:

• Complete half of this assignment questions (1-5) correctly to get back 15%

poll participation grades. Complete all questions (1-10) in this assignment

correctly to get back 25% poll participation grades. (Capped at 100%).

• Submission with less than half questions (≤ 5) completed will not be graded

or granted points back. Submission with more than half questions completed

but not all (≥ 5,≤ 10) will be graded for the half of questions completed.

• Show ALL your work to receive full credit. Unjustified answers will not be

graded.

2. Consider the function

f(x) =

x2 − 1

x − 1

if x < 1 c + ln x if x ≥ 1 (a). Evaluate lim x→1− f(x) (b). Evaluate lim x→1+ f(x) (c). Find a value for the parameter c, so that f is continuous at x = 1. 3. Given f(x) = 4ex + 2e−x ex − e−x Find all vertical and horizontal asymptotes. 4. Find y′ if xy = yx.

The population of yeast cells is modeled by the function n = f(t) = a 1 + be−0.7t where t is measured in hours. At time t = 0 the population is 20 cells and is increasing at a rate of 12 cells/hour. Find the values of a and b. 6. If a snowball melts so that its surface area decreases at a rate of 1 cm2/min, find the rate at which the diameter decreases when the diameter is 10 cm. (The surface area of a snowball is A = 4πr2). 7. Consider the function f(x) = x x2 + 1 (a). Find the intervals on which f is increasing and decreasing. (b). Find the intervals on which f is concave up and concave down. (c). Find the local maximum and local minimum values of f. (d). Find the inflection points of f. 8. Use a linear approximation to estimate cos 29◦ 9. A piece of wire 10 m long is cut into two pieces. One piece is bent into a square and the other is bent into circle. How should the wire be cut so that the total area enclosed is a maximum. 10. In a murder investigation, the temperature of the corpse was 32.5◦C at 1:30PM and 30.3◦C an hour later. Normal body temperature is 37.0◦C and the temperature of the surroundings was 20.0◦C. When did the murder take place?
