The polynomial 0.041h-0.018a-2.69 can be used to ?

Question

estimate the lung capacity in liters of a female with height h, in centimeters, and age, a, in years. Find the lung capacity of a 50 year old woman who is 160 centimeters tall.

Her lung capacity approximately____liters?

Answer 1

h = 160 cm

a = 50 yrs

Lung capacity = 0.041h-0.018a-2.69

Substitute a and h to get Lung capacity

Lung capacity = 0.041(160) - 0.018(50) -2.69

= 6.56 - 0.9 - 2.69

= 2.97 Litres
