Find the exact value of Cosine (StartFraction 5 pi Over 6 EndFraction) cosine (StartFraction pi over 12 EndFraction) + sine (StartFraction 5 pi Over 6 EndFraction) sine (StartFraction pi Over 12 EndFraction)

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
