Mr. Gill is draining his pool. The pump he is using changes the water level by −214 inches per hour. A stronger pump would drain the pool 212 times as fast. What would the change in water level be per hour if Mr. Gill used the stronger pump?

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.
