the researchers have also determined that the current rate of the rise in water level is twice the 1880 to 2009 rate. assuming that this new rate began in 2009, you can use the function g(x) = 3.2(x - 2009) + 206, which models the total rise in water level in mm since 1880 for any year x, beginning in 2009.1. what is the domain of g(x)?2. write a simplified function, g(x)3. according to the model, what will be the total rise in water level by 2025?4. when will the total rise in water level be equal to about half a meter?please help and thank you!!

. A hawk flying at a height of 60 feet spots a rabbit on the ground. If the hawk dives at a speed of 55 feet per second, howlong will it take the hawk to reach the rabbit?(Hint: A model for the vertical motion of a projected object is given by the equation h = -16t2 + vt + s, where h is the heightin feet, t is the time in seconds, v is the initial velocity in feet per second, and s is the starting height of the object in feet. Usethis equation to find the time taken by the hawk to reach the rabbit.
