The polynomial 0.041h-0.018a-2.69 can be used to estimate the lung capicity in liters of a female with h, in centimeters and age a, in years. Find the lung capacity of a 50 year old woman who is 180 centimeters tall
.
The problem defines:
h as 180 cm
a as 50 years
.
Plug into the given equation and solve:
0.041h-0.018a-2.69
0.041(180)-0.018(50)-2.69
= 7.38-.9-2.69
= 6.48-2.69
= 3.79 liters
