An engineer is testing an experimental engine for its efficiency. The engineer runs the
engine
under load and measures its output at intervals of thours. At the beginning of the test the
engine was outputting 2900 watts. At the first interval the engine was down to 2892.75
watts. Write an exponential decay formula to model this situation.
