The body mass index (BMI) of a person is defined by B ( m , h ) = m h 2 where m is the person’s mass (in kilograms) and h is the height (in meters). Draw the level curves B ( m , h ) = 18.5, B ( m , h ) = 25, B ( m , h ) = 30, and B ( m , h ) = 40. A rough guideline is that a person is underweight if the BMI is less than 18.5; optimal if the BMI lies between 18.5 and 25; overweight if the BMI lies between 25 and 30; and obese if the BMI exceeds 30. Shade the region corresponding to optimal BMI. Does someone who weighs 62 kg and is 152 cm tall fall into this category?

A 20 foot ladder rests on level ground; its head (top) is against a vertical wall. The bottom of the ladder begins by being 12 feet from the wall but begins moving away at the rate of 0.1 feet per second. At what rate is the top of the ladder slipping down the wall? You may use a calculator.
