(2x² - 40x² – 28) /(x² – 5x – 2)
erastova [34]

Answer:

x = i sqrt(14/19) or x = -i sqrt(14/19)

Step-by-step explanation:

Solve for x:

(-38 x^2 - 28)/(x^2 - 5 x - 2) = 0

Multiply both sides by x^2 - 5 x - 2:

-38 x^2 - 28 = 0

Add 28 to both sides:

-38 x^2 = 28

Divide both sides by -38:

x^2 = -14/19

Take the square root of both sides:

Answer: x = i sqrt(14/19) or x = -i sqrt(14/19)

ASAP PLEASE ANSWER quadrilateral ABCD is dilated at center (0,0) with scale factor 1/2 to form quadrilateral A'B'C'D'. wha is th
zhenek [66]

Answer:

|A'B'|=\sqrt{5}

Step-by-step explanation:

The points A and B have coordinates at (0,4) and (4,2) respectively.

The distance formula can be used to find the length of AB.

|AB|=\sqrt{(4-0)^2+(2-4)^2}

|AB|=\sqrt{(4)^2+(-2)^2}

|AB|=\sqrt{16+4}

|AB|=\sqrt{20}

|AB|=2\sqrt{5}

Since quadrilateral ABCD was enlarged with  a scale factor of \frac{1}{2}.

The length of A'B' is

\frac{1}{2}|AB|

=\frac{1}{2}\times2\sqrt{5}

\therefore |A'B'|=\sqrt{5}

Tems11 [23]

Answer:

Explanatory variable: Extra support by faculties

Response variable: whether community college students who have assess into elementary algebra could be successful if they were placed directly into college-level statistics.

Confounding Variable: Ability of students to get passing grades.

It is an experiment to check if the hypothesis is true.

Step-by-step explanation:

An explanatory variable is a type of independent variable. An explanatory variable is that variable that explains changes in another variable. It can be anything that might affect the response variable. The explanatory variable is used to predict or explain differences in the response variable. In an experimental or research study, the explanatory variable is the variable that is manipulated by the researcher.

From the information given,

Explanatory variable: Extra support by faculties.

The response variable is also known as the dependent/outcome variable. Here, its value can be predicted or its variation can be explained by the explanatory variable. In an experimental study, this is the outcome that is measured after manipulation of the explanatory variable

From the question above,

Response variable: whether community college students who have assess into elementary algebra could be successful if they were placed directly into college-level statistics.

A confounding variable is that outside influence that changes the effect of a dependent and independent variable. This extraneous influence is often used to influence the outcome of an experimental design. The Confounding Variable in the above is:

Confounding Variable: Ability of students to get passing grades.

It is an experiment to check if the hypothesis is true.
