Estimating heights. An anthropologist can use certain linear functions to estimate the height of a male or female, given the length of certain bones. The humerus is the bone from the elbow to the shoulder. Let x = the length of the humerus, in centimeters Then the height, in centimeters, of a male with a humerus of length x its given by
The height, in centimeters, of a female with a humerus of length x is given by
A 26-cm humerus was uncovered in some ruins.
a. If we assume it was from a male, how tall was he?
b. If we assume it was from a female, how tall was she?

Roman and Shanice come along in a truck to help pull her out. They attach one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude and its direction angle from the positive x-axis. 119 lb 20.2° 377 lbarrow_forward
