A patient’s temperature was 97.0 °F at 8:05 A.M. and 101.0 °F at 12:05 P.M. If the temperature change with respect to elapsed time was linear throughout the day, what would the patient’s temperature be at 3:35 P.M.?
The graph shows a city's daily rate of use of electricity (in millions of kilowatts). Estimate the total daily usage of electricity by summing the area of rectangles. Use the left endpoints, then the right endpoints, then give the average of those results as the answer. Let the width of each rectangle be 2 hours. 14 12- 10- 8- 6- 4- 2- Midnight 4 AM. 8A.M. Noon 4 PM. 8 P.M. Midnight The estimate of the city's total daily usage of electricity for the given day, found by averaging the estimates using left and right endpoints, is million kw-hrs. (Round to the nearest whole number as needed.) Millions ofkilowatt hours

At 8:30 a.m., a coroner was called to the home of a person who had died during the night. In order to estimate the time of death, the coroner took the person's temperature twice. At 9:00 a.m. the temperature was 87.3°F, and at 11:00 a.m. the temperature was 84.2°F. From these two temperatures, the coroner was able to determine that the time elapsed since death and the body temperature were related by the formula T - 70 t = -10 In 98.6 – 70 where t is the time in hours elapsed since the person died and T is the temperature (in degrees Fahrenheit) of the person's body. (This formula is derived from a general cooling principle called Newton's Law of Cooling. It uses the assumptions that the person had a normal body temperature of 98.6°F at death, and that the room temperature was a constant 70°F.) Use the formula to estimate the time of death of the person. (Round your answer to the nearest hour.) A.M.

At 8:30 a.m., a coroner was called to the home of a person who had died during the night. In order to estimate the time of death, the coroner took the person's temperature twice. At 9:00 a.m. the temperature was 84.2°F, and at 11:00 a.m. the temperature was 81.6°F. From these two temperatures, the coroner was able to determine that the time elapsed since death and the body temperature were related by the formula t = −10 ln T − 70 98.6 − 70 where t is the time in hours elapsed since the person died and T is the temperature (in degrees Fahrenheit) of the person's body. (This formula is derived from a general cooling principle called Newton's Law of Cooling. It uses the assumptions that the person had a normal body temperature of 98.6°F at death, and that the room temperature was a constant 70°F.) Use the formula to estimate the time of death of the person. (Round your answer to the nearest hour.)
