25. Anthropologists use a linear model that relates human femur (thighbone) length to height. The model allows an anthropologist
to determine the height of an individual when only a partial skeleton (including the femur) is found. Here we find the model by analyzing the data on femur length and height for the eight males given in the following table.
(c) An anthropologist finds a human femur of length
How tall was the person?
(c) An anthropologist finds a human femur of length

First lets look at our graph of y = cos x
***First picture***
Next lets look at a <span>vertical stretch.
***Second picture***
To vertically stretch y = cos x, we need to multiply cos by a number greater than 1. I am going to use 2.
Standard Form: y = cos x (Red Line)
Vertical Stretch: y = 2 cos x (Blue Line)
Lets look at a vertical shrink
***Third picture***
To create a vertical shrink, you multiply the cos by a number less than 1. I am going to use .5
</span>Standard Form: y = cos x (Red Line)
Vertical Shrink: y = .5 cos x (Green Line)
Now lets look at horizontal stretch.
***Forth picture.***
To create a horizontal stretch, you multiply the x by a value less than 1. I am going to use .5
Standard Form: y = cos x (Red Line)
Vertical Stretch: y = .5 cos x (Orange Line)
Finally, to create a horizontal shrink, you multiply the x by a value greater than 1. I am going to use 2.
***Fifth picture.***
Standard Form: y = cos x (Red Line)
Vertical Shrink: y = 2 cos x (Purple Line)
