The circle (x-2)^2 + (y-5) =16 It shift up 3 units vertically and to the left 1 unit horizontally. Where is the center of the circle? What is it's radius? What is the equation?

The temperature of a chemical solution is originally 21 ? c . a chemist heats the solution at a constant rate, and the temperature of the solution 75 ? c after 1212 12 minutes of heating. the temperature, tt t , of the solution in ? c is a function of x , the heating time in minutes. write the function's formula.
