PLEASE HELP A conservation biologist is observing a population of bison affected by an unknown virus. Initially there were 110 individuals but the population is now decreasing by 2% per month. Which function models the number of bison, b, after n months?
b= 110(.8)^N
b= 110(.2) ^N
b= 110(.98)^n
b= 110(.02)^n

This is so harddd! solve. 1 + 1 = solve 4 + 4 = solve 3 x 3

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x
