December 1, 2022
Review these terms and concepts related to algebra that may be tested on the Quantitative Reasoning section of the GRE test.   absolute value
We use the absolute value symbol to indicate that the length is a positive number because the absolute value of any number is positive.
constant
Also, there is still one of the original problems that Hubble was designed to help solve, which is determining how fast the universe is expanding—something called the Hubble constant.
conversion
A sudden conversion of a large amount of cryptocurrency can also be dangerous, causing the price of the coin to collapse as it’s turned into dollars.
domain
When a finite sequence is defined by a formula, its domain is a subset of the non-negative integers.
exponential
The curve of growth can be plotted as an exponential line—1, 2-, 4-, 8-, 16-fold growth—until the culture turns turbid, and the sugar source has been exhausted.
intercept
We will take a look at a few applications here so you can see how equations written in slope– intercept form describe real world situations.
inverse
There is a curious inverse relationship in modern physics between the tininess of the thing being sought and the scale of facilities required to do the searching.
logarithm
The logarithm of a number is simply the power to which 10 must be raised to equal the number in question.
matrix
Blue Team had their databases and matrixes and methodologies for systematically understanding the intentions and capabilities of the enemy.
