The average annual salary of the employees of a company in the year 2005 was $70,000. It increased by the same factor each year and in 2006, the average annual salary was $82,000. Let f(x) represent the average annual salary, in thousand dollars, after x years since 2005. Which of the following best represents the relationship between x and f(x)?f(x) = 70(1.17)x f(x) = 82(1.17)x f(x) = 70(2.2)x f(x) = 82(2.2)x

HELP MEEEE PLZZZZZZZZZZZZZZZZZZZZZZZThis graph shows the water level in a bathtub, in inches, over time (in minutes).What situation could match the graph?A.Alison empties the water from the tub and then fills it halfway up again. She allows the water to sit for a couple of minutes and then checks to see if it is at the right temperature. It is a little hot, so she adds some more cold water to the tub. She takes a short bath and then allows half of the water to drain from the tub.B.Alison turns on the water and allows it to run in the tub for a few minutes. Then she decides the water is too hot and allows some of the water to drain out of the tub before filling it up the rest of the way. After the tub is full, Alison takes a short bath. After the bath, Alison allows the water to completely drain from the tub.C.Alison turns on the water and allows it to run in the tub for a few minutes.
