Terms in this set (17)
common ratio
The ratio of successive terms of a geometric sequence.
compound interest
A special application of exponential growth.
Constant
A monomial that is a real number.
cubed root
If a^3=b, then a is the cube root of b.
exponential decay
When an initial amount decreases by the same percent over a given period of time.
exponential equation
An equation in which the variables occur as exponents.
exponential function
A function that can be described by an equation of the form y = a^x, where a>0 and a cannot equal 1.
exponential growth
When an initial amount increases by the same percent over a given period of time
geometric sequence
A sequence in which each term after the first is found by multiplying the previous term by a constant r, called the common ratio.
monomial
A number, a variable, or a product of a number and one or more variables.
negative exponent
For any real number a excluding 0 and any integer n, a^-n = 1/a^n and 1/a^-n = a^n.
nth root
If a^n = b, for a positive integer n, then a is an nth root of b.
order of magnitude
The order of magnitude of a quantity is the number rounded to the nearest power of 10.
rational exponent
For any positive real number b and any integers m and n>1, b^m/n = (the nth root of b)^m or (the nth root of b^m. m/n is the rational exponent.
recursive formula
Each term is formulated from one or more previous terms.
scientific notation
A number in scientific notation is expressed as a x 10^n, where a is greater than or equal to 1 but less than 10 and n is an integer.
zero exponent
For any nonzero number a, a^0 = 1. Any nonzero number raised to the zero power is equal to 1.
