Air pressure decreases exponentially with increases in elevation. The air pressure, y, (in atm units) at a given elevation, I, (in meters) can be modeled using equation y = e-los, where k is the decay constant.
At an elevation of 5486 m where the air pressure is 0.5 atm, what is the value of k?
A k=
In( 5486)
0.5
O B. k=
In(0.5)
5486
Ock=-In ( 545
D. k=-In ( 59.56

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
