28. Oil Production in Mexico
Crude oil production by Pemex, Mexico's national oil company, for 2008-2013 could be approximated by P(t) = 0.017t^2 - 0.4t + 5.23 million barrels per day (8 ≤ t ≤ 13), where t is time in years since the start of 2000. According to the model, approximately when was oil production by Pemex least? What was the oil production at that time? (Round the answer to two significant digits) [HINT: See Example 1.]
