During a chemical reaction, the rate of change of the amount of the chemical remaining is proportional to the amount remaining. At time t=0, the amount of the chemical is 12 moles. At time t=4, the amount of the chemical is 4 moles. At what time t is the amount of the chemical 3 moles? (A mole is a unit of measure used in chemistry.) A = 3root2 B = 9/2 C = 4ln3/ln4 D = 4ln4/ln3
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.
