PLEASE HELP !! A researcher in North America discovers a spear head that contains 78% of its original amount of C-14.
N = Noe^-kt
No= initial amount of C-14 (at time t = 0)
N = amount of C-14 at time t
K = 0.0001
t = time, in years

Use the knowledge of x- and y- intercepts to choose the correct graph of the equation 3x+6y=6

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
