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 some rules used to determine the number of significant figures and how they differ for addition and subtraction vs multiplication and division?

For multiplication/division, use the least number of significant figures (ie 6.24 * 2.0 = 12). For addition subtraction, use the least specific number (ie 28.24 - 2.1 = 26.1)


What are the values in determining the number of significant figures involving the four mathematical operations?

addition multiplication division subtraction


What is the rules in adding and subracting significant figures?

The smallest significant place of the numbers is rounded in either addition or subtraction (for example: 2.038 +0.12 +0.1 =2.3).


When you add or subtract what is the rule for determining the number of significant figures in the answer?

= significant figures = and got For addition and subtraction, the result should have as many decimal places as the measured number with the smallest number of decimal places.


When finding significant figures for multiplication and division problems you go by the least number of?

multiplication/division: least number of significant figures addition/subtraction: least number of numbers to the right of decimal point


How do you do significant figures when more than one operation is involved?

It depends on the operation - for multiplication, the ammount of significant figures is the same as the multiple that has the least. Same for division. For subtraction and addition, the significant figures are decided by the least ammount of spaces past the decimal in the answer. For example, 30.7+2.111111111 would be 30.8


Rules on addition and subtraction of significant figures?

Round to the least precise number. 3.4 + 3= 6.4 which becomes 6.


Rules in determining significant figures in four fundamental operations?

The simple rule is: no more significant figures than the least accurate of the values in the computation. For multiplication and division, the result should have as many significant figures as the measured number with the smallest number of significant figures. For addition and subtraction, the result should have as many decimal places as the measured number with the smallest number of decimal places. (Rounding off can be tricky, but that would be another thread)


What is the number of significant figures in 546 km?

3 of them.


How many significant figures would the sum of 0.582and 324.6 have?

4, for addition and subtraction you add or subtract the numbers and round to the smallest digit of the number that is less specific. In this case the 6 in 324.6.


How do you determine how many significant figures to keep in an answer obtained by adding and subtracting?

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.


Determine the number of significant figures in the measurement 0.0030?

The leading zeros are never counted as significant figures, therefore the answer is two.

You use the most figures that you can accurately determine.


How many significant figures should be reported in the answer to 1.26 x 3.14159?

Three, so the answer would be 3.96. Always use the number with the smallest amount of significant figures to determine the amount of significant figures will be in the solution.


Determine the number of significant figures in 1.056 ml?

1.056ml has four significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.


How do you determine the significant figures in your measurements?

The rules for identifying significant figures when writing or interpreting numbers are as follows: All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5). Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3. Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2. Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.
