Question 3. (Based on OpenStax Calculus, Volume 1, section 4.3, exercises 142 and 143) Assume that during the California gold rush, the amount of gold per year produced t years after the gold rush started was 25t t2 +16 million ounces. When did the local and absolute maximum and minimum gold production occur, and what were the production levels? Assume the gold rush lasted 40 years, so that 0 S t3 40. You may use a calculator for numeric calculations. (See the book's discussion just before exercises 142 and 143 on page 378 of our PDF version for more information.)
