An ideal diameter d, in feet, of a ship's propeller is given by the formula d= ch/5,-3/5 Here h is the horsepower of the engine driving the propeller, r is the (maximum) number revolutions per minute of the propeller, and c is a constant. In both parts, give your answer in terms of a percentage. (Round your answers to two decimal places.) (a) If the horsepower is increased by 20% while the number of revolutions per minute remains the same, how is the propeller diameter affected? The propeller diameter (increases v by %. (b) If the horsepower remains the same while the number of revolutions per minute is increased by 20%, how is the propeller diameter affected? The propeller diameter ( decreases by
