Question 195748: the polynomial 0.41h-0.018a-2.69 can be used to estimate the lung compacity, in liters,of a female with height "h", in centimeters, and age "a", in years. find the lung compacity of a 50 year old woman who is 160 centimeters tall.
Answer by MathTherapy(10551)   (Show Source):
You can put this solution on YOUR website! Since “h” represents an individual’s height, and “a” their age, and
Since the polynomial 0.41h – 0.018a – 2.69 is used to calculate lung capacity, then a person who’s 160 cm tall, and 50 years-old will have a lung capacity of:
0.41(160) – 0.018 (50) – 2.69
65.6 - .9 – 2.69 = 62.01
Therefore, the lung capacity, in liters, of this individual is 62.01.
