The power P in watts delivered to a small light bulb and R is its resistance in Ohms. The current is given by P=I²R, where I is the current in amperes flowing through the bulb, and Ris its resistance in ohms. The current is given by I=5-0.001t and the resistance is given by R=10+0.08t, where t is time measured in seconds. Determine the rate of changeof power, after t seconds, and 10 seconds.
