Best Answer

If your question was 'what is 216 to one significant figure', the answer would be 2. This is because the two means two hundred. If your number was 0.216 and you had to round it to one significant figure it would also be 2, but if your number is 0.203 and you had to round it to two significant figures you would say 20 this is because you only count the zeros as significant figures after an actual number. For example; 0.31 to two significant figures would be 31 but 0.301 to two significant figures would be 30.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

List of the significant figure rule?

Each measurement is considered to have a certain number of what are called significant digits or significant figures ( aka sig figs or sig.digs ) . Rules for Identifying the Number of Significant Digits in a Number Rules 1)Any nonzero (digits from 1 to 9 ) digits are significant . 2)Any zeroes found between two significant digits are significant . 3)Any zeroes that are found to the right of both a significant digit and a decimal place are significant . Examples from the Rules Above According To Each Rule 1)Number 942 , with three nonzero digits , shows 3 significant digits 2)Number 50003 , with 2 nonzero digits and 3 zeroes between and significant digits , shows 5 significant digits . 3)Number 75.00 , with 2 nonzero digits and 2 zeroes that are to the right of both a significant digit and a decimal shows 4 significant digits . Always consider each rule and try memorizing them ,Practice and Memorize
