38. Changes in Temperature T ( t ) is the temperature on a hot summary day at time t hours. a. If T ' ( 10 ) = 4 , by approximately how much will the temperature rise from 10 : 00 to 10 : 45 ? b. Which of the following two conditions is the better news if you do not like hot weather? Explain your answer. i) T ( 10 ) = 95 , T ' ( 10 ) = 4 , T ' ' ( 10 ) = − 3 ii) T ( 10 ) = 95 , T ' ( 10 ) = − 4 , T ' ' ( 10 ) = 3
