Exam Questions and Solutions
-
Question 1a: Interpreting C(200) = 100,000. It will cost $100,000 to manufacture 200 iPhones.
-
Question 1b: Interpreting C'(200) = 500. It costs $500 to make one additional iPhone (at a production level of 200 iPhones).
-
Question 1c: Approximating the cost of making 203 iPhones. Calculate the cost for 200 iPhones ($100,000) plus the additional cost of making three iPhones ($500/phone * 3 phones = $1,500). Therefore, the total approximate cost is $101,500.
Limits and Continuity
-
Question 2a: Finding the limit of f(x) as x approaches 7. The limit from the left (x→7−) is 48; from the right (x→7+) is 48. Thus, the limit is 48.
-
Question 2b: Finding the limit of (2x + 3)/(4x⁵ − 1) as x approaches infinity. The limit is 0.
-
Question 2c: Finding the limit of (4x⁵ − x)/(7x⁵ + 5x) as x approaches infinity. The limit is 4/7.
Compound Interest
- Question 3: Calculating the time to reach $90,000 in an account with $30,000 invested at 7.27% compounded continuously. The exact time is ln(3) / ln(1.0727) years.
Limits using Graph
- Question 6: Determining various limits and function values by inspecting the provided graph. Includes limits from the left and right, function values, and continuity at specified points on the graph. (Answers for each limit/function value are provided in the table; no further explanation needed)
