(a) Explanation Given information: The equation for the temperature on 22 January 1943, is approximated by T = − 2.15 m + 54 where T is temperature in degree Fahrenheit and m is the number of minutes since 9:00 that morning. Calculation: Consider the equation for the temperature, T = − 2.15 m + 54 . Since and m is the number of minutes from 9:00 for that morning. For time 9 : 01 A .M . , the corresponding value of m is 1. Substitute 1 for m in T = − 2.15 m + 54 and solve for T . T = − 2.15 ( 1 ) + 54 = − 2.15 + 54 = 51.85 ° Therefore, the temperature in degree Fahrenheit is 51.85 ° . For time 9 : 08 A .M . , the corresponding value of m is 8. Substitute 8 for m in T = − 2.15 m + 54 and solve for T . T = − 2 (b) To determine To graph: The equation T = − 2.15 m + 54 where T is temperature in degree Fahrenheit and m is the number of minutes since 9:00 that morning and then find the temperature at 9:15 A.M. (c) To determine To calculate: The time at which the temperature stop to drop at − 4 ° F when the equation is T = − 2.15 m + 54 where T is temperature in degree Fahrenheit and m is the number of minutes since 9:00 that morning.
