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.

Use the following information. Michael Kasha, of Florida State University, used physics and mathematics to design a classical guitar. He used the model for the frequency of the vibrations on a circular plate v = 2.6t / d2 sqrt( E/P) where v is the frequency (in vibrations per second), t is the plate thickness (in millimeters), d is the diameter of the plate, E is the elasticity of the plate material, and ? is the density of the plate material. For fixed values of d, E, and the graph of the equation is a line, as shown in the figure. Estimate the frequency when the plate thickness is 4 millimeters.______ vibrations/sec

Consider the current flow of electricity within an electrical circuit. The formula of Ohm's Law says that when electric current is flowing through a resistor, the current i (measured in amps) can be calculated from the voltage v (measured in volts) and the resistance R of the resistor (measured in ohms). Complete Part (a) and Part (b) using the given formula: R Part (a). The resistor in a radio circuit was measured to be 5000 ohms. I. What is the formula for the current i in the radio circuit? Use lower-case letter v for voltage. IL.
