The polynormial 0.041h-0.018a-2.69 can be used to estimate the lung capacity in liters of a female with height h, in cetimeters, and age a, in years. Find the lung capacity of a 40-year old woman who is 190 centimeters tall. Round to the nearest hunderd.
To find the lung capacity of a 40-year-old woman who is 190 centimeters tall, we can substitute the given values into the polynomial equation 0.041h - 0.018a - 2.69.
Given:
h = 190 centimeters
a = 40 years
Substituting these values into the equation:
0.041(190) - 0.018(40) - 2.69
Now, we can simplify the equation step by step:
7.79 - 0.72 - 2.69
Next, we add/subtract the values within parentheses:
7.79 - 0.72 - 2.69 = 5.38 - 2.69 = 2.69
Therefore, the lung capacity of a 40-year-old woman who is 190 centimeters tall is approximately 2.69 liters.
