Factorise using suitable identities (0.1x-0.2y)^2

Mathematics
1 answer:
Sav [38]3 years ago
3 0

Answer:

Step-by-step explanation:

(a - b)² = a² - 2ab + b²

a = 0.1x

b = 0.2y

(0.1x - 0.2y)²= (0.1x)² - 2*0.1x*0.2y + (0.2y)²

                   = (0.1)²x² - 0.04xy + (0.2)²y²

                   = 0.01x² - 0.04xy + 0.04y²

If YV = 28 in, find the length of the major arc VYX. Round to the nearest tenth ( one decimal place).
denpristay [2]

Answer:

VYX=84.3in

Step-by-step explanation:

Given

YV = 28in

\angle WZX = 15^\circ

See attachment

Required

Determine the length of VYX

First, calculate the major angle VZX

\theta = \angle VZX = 360 - \angle WZX

\theta = \angle VZX = 360 - 15

\theta = \angle VZX = 345

\theta = 345

The length of arc VYX, is:

L=\frac{\theta}{360} * 2\pi r

Where

r = \frac{1}{2} * Diameter

r = \frac{1}{2} * YV

r = \frac{1}{2} * 28

r = 14

So:

L=\frac{\theta}{360} * 2\pi r

L=\frac{345}{360} * 2 * \frac{22}{7} *14

L=\frac{345}{360} * 2 * 22 *2

L=\frac{345* 2 * 22 *2}{360}

L=\frac{30360}{360}

L=84.3in

Hence, the length of VYX is:

VYX=84.3in

Figure M and it’s congruent image, figure N, are graphed on the coordinate plane below.
mixer [17]

The reflection over the line y = x - 3 will take figure M onto its congruent image, figure N.

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

As we can see in the graph there are two shapes are shown.

Figure M and Figure N

The sequence of transformations that will take figure M onto its congruent image, figure N is:

First, we need to draw a line that passes through (3, 0) and (0, -3)

The equation of the line is:

\rm y+3=\dfrac{\left(-3\right)}{-3}\left(x\right)

y + 3 = x

y = x - 3

The reflection over the above line will take figure M onto its congruent image, figure N.

Thus, the reflection over the line y = x - 3 will take figure M onto its congruent image, figure N.

The dependent variable depends on a particular situation. The independent variable does depends on the result of an experiment. The controlled variable is a variable whose value is constant.

What is dependent variable?

The variable being measured or tested in an experiment is known as the dependent variable. The results of the participants' tests, for instance, since that is what is being measured, would be the dependent variable in a study looking at how tutoring affects test scores.

What is independent variable?

This isn't the same as an experiment's independent variable, which is a variable that can stand on its own. Tutoring would be the independent variable in the aforementioned case. The dependent variable (test results), however, may alter depending on the independent variable (tutoring).

What is controlled variable?

Anything kept constant or constrained in a research study is referred to as a control variable. Despite not being relevant to the study's objectives, this variable is controlled because it might have an impact on the results.

Numbers called parameters are used to define the characteristics of entire populations. Statistics are numerical representations of sample characteristics. One population parameter is the average income in the United States.
