After sitting in a refrigerator for a while, a turkey at a temperature of 40°F is placed on the counter and slowly warms closer to room temperature (73°F). Newton's Law of Heating explains that the temperature of the turkey will increase proportionally to the difference between the temperature of the turkey and the temperature of the room, as given by the formula below: T = Ta + (To – Ta)e kt Ta =the temperature surrounding the object То = the initial temperature of the object t = the time in minutes T= the temperature of the object aftert minutes NE $4 8. 9 7 4 e k 5

The number of seconds that it takes a pendulum to swing back and forth once (called its period) is given by P=1.11.L¹1/2 where L is the length of the cable or chain holding the pendulum, measured in feet. Suppose you are making a rope swing and want the period of the swing to be 7 seconds. How long should the rope swing be? L= feet Round to 2 decimal places

A certain drug breaks down in the human body at a rate of 12% per hour. The initial amount of the drug in thebloodstream is 6 milligrams. Round to the nearest hundredth.Equation _________________________ Hour = t         mg of drug          Hour = t            mg of drug     0                                                   6     1                                                   7     2                                                   8     3                                                   9     4                                                  10     5
