- A patient’s temperature was 97.0 °F at 8:05 A.M. and 103.4 °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.? answer in FarehnheitHow did you get the equation of H(t)The mass of a star similar to the Sun is 2.04 ✕ 1030 kg, and the mass of an atom of hydrogen, of which the Sun is mostly composed, is 1.67 ✕ 10-27 kg. How many atoms are in the star?
- The world population in billions is approximately P = 7.4e0.010" where t is in years since 2016. Estimate the relative rate of change of population in 2020 using this model and the values of At below. Round your answers to three decimal places. (a) At = 1 The relative rate of change is % per year. the absolute tolerance is +/-0.001 (b) At = 0.1 The relative rate of change is % per year. (c) At = 0.01 The relative rate of change is % per year.Although human lung capacity is about 3 liters per lung, the tidal volume, representing the amount of air that is breathed in and out with each breath is much -3 less, typically about 250 cm7 per lung. The cycle of inhalation and exhalation during normal activity can be represented as a sine curve, as shown in the figure below, where the amount of air in each lung before inhalation begins is about 1.09 liters (the functional residual capacity of the lung) and the time on the horizontal axis has been calculated with the average adult breathing rate of 16 breaths per minute. Volume of air in lungs (L) 1.34 1.09 mm minimum height maximum height 15 We can model each lung as a cylinder of radius 5.95 cm in which one end cap is free to move up and down, increasing and decreasing the volume of the model lung during the breathing process. (a) Using the data above, calculate the minimum and maximum heights (in cm) of the model lung during the breathing process. (Round your answers to at least…They determined that they can use this exponential model to predict the number of trees in the forest that will be infected after y years
