Question

Subtract:−4a2 + 3 /5 a −6 from 3a2 – 2a + 6.

Answer 1

Step-by-step explanation:

Your kneecap (patella) is attached by a tendon to your quadriceps muscle. This tendon pulls at a 10° angle relative to the femur, the bone of your upper leg. The patella is also attached to your lower leg (tibia) by a tendon that pulls parallel to the leg. To balance these forces, the end of your femur pushes outward on the patella. Bending your knee increases the tension in the tendons, and both have a tension of 60° when the knee is bent to make a 70° angle between the upper and lower leg. What force does the femur exert on the kneecap in this position"
