Below are some examples of these types of functions: y = 2x + 1 y = 3x2 - 5x + 3 y = Sin(x) x2 + y2 = 4 y2 = x3 - Tan(x). These algebraic functions are all different and have different properties. It is often useful to have a visual way to look at these functions. Graphs provide such a tool.
Did you know: About 78% of the Average Human Brain Consists of Water. The human brain is the main part of the nervous system, coordinating all the functions of the body via electric impulses. The human brain hosts approximately 80 to 120 billion nerve cells and it is largely made of water. Water is of major importance to all living things; in some organisms, up to 90% of their body weight comes from water. Up to 60% of the human body is water, the brain is composed of 70% water, and the lungs are nearly 90% water. Lean muscle tissue contains about 75% water by weight, as is the brain; body fat contains 10% water and bone has 22% water.
Question: What Are the Elements in the Human Body? Answer: Most of the human body is made up of water, H2O, with cells consisting of 65-90% water by weight. Therefore, it isn't surprising that most of a human body's mass is oxygen. Carbon, the basic unit for organic molecules, comes in second. 99% of the mass of the human body is made up of just six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
