The pressure P on a diver's body is a linear function of the diver's depth x feet below the surface of the water. At the water's surface the pressure is 1 atmosphere. When the diver is at a depth of 100 feet, the pressure is about 3.92 atmospheres. What is the pressure of the water on the diver at a depth of 225 feet?
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
