What are the parts of an algebraic expression, and how do they relate to polynomial expressions?

Arlecino [84]

The parts of algebraic expressions related to polynomials are variables and coefficients.

<h3>What are the parts of algebraic expressions?</h3>

The parts of algebraic expressions are;

Variables which are letters that represent numbers
Coefficients are numbers that multiply the variables
Constant is a number that is not multiplied by any variable

Polynomials are algebraic expressions composed of variables, constants and exponents, that are combined using the mathematical operations such as addition, subtraction, and multiplication

Polynomials consists of variables and coefficients. The variables in polynomials are also called indeterminates. The coefficients also multiply this variables.

Thus, the parts of algebraic expressions related to polynomials are variables and coefficients.

12. Find the distance between points P(-1, 2) and Q(-3, 4).

marusya05 [52]

Answer:

D=2.82

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (-1,2)$

$(x_2,y_2) = (-3,4)$

Replacing these values in the distance formula

$D =\sqrt{(-1-(-3))^2+(2-4)^2}$

$D =\sqrt{(-1+3)^2+(-2)^2}$

$D =\sqrt{(2)^2+4}$

$D =\sqrt{4+4}$

$D =\sqrt{8}$

$D= 2.8284$

Hence the Distance is 2.82 units

?÷(−7)=(−4) what is the missing number

Hunter-Best [27]

Answer:

The answer is 28.

Step-by-step explanation:

To find the solution, you must multiply the other two numbers together to find the original number that is divided.

-7 * -4 = 28 Answer

28/-7 = -4

Hope this helps!

A researcher thinks that a person's mood has an effect on how helpful that person is likely to be. To test this, the researcher

eimsori [14]

Answer:

One possible confound for the experiment is the attitude of the research assistants.

Step-by-step explanation:

A confounder simply means a variable that has impact in influencing both the dependent variable and independent variable, causing a spurious association.

So, we can conclude that the attitudes of the research assistants have positive and negative impacts in determining the reactions of both participants in the experiment.

The rudeness of a research assistant will negatively impact the response of the participant allocated to him/her.

The calmness of the other research assistant will positively impact the response of the participant allocated to him/her.
