The graph in the figure shows the temperature T = T(v) adjusted for wind chill as a function of the velocity v of the wind when the thermometer reads 30 degrees Fahrenheit. The adjusted temperature T shows the temperature that has an equivalent cooling power when there is no wind.15 20 25 30 35 40 45= Wind speed (mph)(a) At what wind speed is the temperature adjusted for wind chill equal to 0?27.5✔✔mph(b) Your answer in part (a) is the solution of an equation involving T(v). Which equation?T(v) =Explain your reasoning.X(c) At what value of v would a small increase in v have the greatest effect on T(v)? In other words, at what wind speed could you expect a small increase in wind speed to cause the greatest change in wind chill?45xmph

For a person at rest, the velocity v (in liters per second) of airflow during a respiratory cycle (the time from the beginning of one breath to the beginning of the next) is modeled by v=0.85sint/3, where t is the time (in seconds). a Find the time for one full respiratory cycle. b Find the number of cycles per minute. c Sketch the graph of the velocity function. Use the graph to confirm your answer in part a by finding two times when new breaths begin. (Inhalation occurs when v0, and exhalation occurs when v0.)
Use function notation to represent the change in Sam's height above the ground over the time interval from t=4 seconds since the Ferris Wheel began moving to t=10 seconds since the Ferris Wheel started moving. What was the change in Sam's height above the ground as the amount of time since the Ferris Wheel started moving increases from 4 seconds to 10 seconds? Use function notation to represent the average rate of change of Sam's height above the ground (in feet) in terms of the amount of time (in seconds) since the Ferris Wheel started moving on the interval from t=4 to t=10. Determine the value of the average rate of change (represented in part e) of Sam's height above the ground (in feet) in terms of the amount of time (in seconds) since the Ferris Wheel started moving, as t increases from 4 to 10 seconds. Select an answer feet seconds feet per second seconds per foot
