When a drug is injected into the bloodstream of a patient through the right arm, the drug concentration in the bloodstream of the left arm t hours after the injection is approximated by for some values a and b. at C(t) = = t² + b' Lab tests show that those values for Artecoadipine are a = 0.25 and b 5.13, for = 0 < t < 24. The model suggests that after injection, the drug concentration of Artecoadipine in the left arm is increasing until some time T hours, and decreasing afterward. Find T. Round to 2 decimal places. hours

The table gives the annual US emissions, H(t), of "super greenhouse gases," in millions of metric tons of carbon-dioxide equivalent.¹ Let t be in years since 2000. ¹Includes HFCs (hydrofluorocarbons), PFCs (perfluorocarbons), SF6 (sulfur hexafluoride), and NF3 (nitrogen trifluoride). www.epa.gov/climate-indicators, accessed October 3, 2019. The units are Year 2002 2004 2006 2008 2010 2012 2014 The integral represents the H(t) 142.3 139.6 144.1 157.5 164.0 170.1 180.1 (a) What are the units and meaning of i 6₂1²³, H(t)dt?

A research group developed the following mathematical model relating systolic blood pressure and age: P(x) = a + bln(x + 1), where P(x) is pressure, measured in millimeters of mercury, and x is age in years. By examining Guilford County hospital records, they estimate the values for Guilford County to be a = 37 and b = 25. Using this model, estimate the rate of change of pressure with respect to time after 15 years. Round to the nearest hundredth (2 decimal places). millimeters per year

A manufacturing company is ready to introduce a new product with a national sales campaign. After extensive test marketing, the market research department estimates that sales (in millions of dollars) will increase at the monthly rate of S'(t) = 10 - 10 e nearest million.) - 0.2t for 0sts24, t months after the national campaign has started. What will the total sales be five months after the beginning of the campaign assuming zero sales at the beginning of the campaign? (Round the answer to the A. $49 million B. $1 million C. $2 million D. $18 million
