This polynomial is said to be able to find the caloric needs, that's the calories, a moderately active woman needs to receive every day when they weigh a certain amount and when they are a certain number of inches tall.
00:19
So this polynomial on 917 plus 6w plus 6h minus 6a.
00:34
And also the a stands for what age the woman would be.
00:39
So we have three different variables in this case, w, which is for weight, h, which is for height, and a, which is for age.
00:49
So what we're going to do is we're going to look into a woman who is 125 pounds.
00:54
This would be w, 125, who for a height, they are 64 inches tall, so we'll use 64 for the h and who is 27 years old.
01:07
So we'll use 27 for the age.
01:09
We're going to take these three values and substitute them into the correct variables.
01:14
So we'll start over here at 917 and we will add 6w.
01:20
But instead of the w, i'm going to put in 125...
