show that the lines x2-4xy+y2=0 and x+y=3 form an equilateral triangle also find area of the triangle
arlik [135]

Given pair of lines are x² + 4xy + y² = 0

⇒ (y/x) ² + 4 y/x + 1 = 0

⇒ y/x = -4±2√3/2 = -2±√3,

∴  The lines y = (-2 + √3) x and y = (-2 - √3) x and x - y = 4 forms an equilateral triangle

Clearly the pair of lines x² + 4xy +y²  = 0  intersect at origin,

The perpendicular distance form origin to x - y = 4 is the height of the

h = 2 √ 2

∵ Area of triangle = h²/√3 = 8/√3

5 of 10<br> What is the decimal multiplier to increase by 2.8%
Verdich [7]

Answer:

1.028

Step-by-step explanation:

The original amount is 100%

Add 2.8% to 100% = 102.8%

Now divide by 100 to find the decimal multiplier

102.8 ÷ 100 = 1.028

hope this helps :)

Find the measure of each interior angle and each exterior angle of a regular 20-gon (a twenty-sided polygon).Measure of each int
ra1l [238]

Given a regular 20-gon ( a 20 sided polygon )

The measure of each interior angle will be given by:

\frac{(n-2)}{n}\cdot180

where n is the number of sides

Substitute with n = 20

So, the measure of each interior angle =

\frac{20-2}{20}\cdot180=\frac{18}{20}\cdot180=162

The sum of exterior angles = 360

So, the measure of each exterior angle = 360/20 = 18

In Problems 1-8, determine the level of measurement of each variable.
lbvjy [14]

The level of measurement of each given variable are:

1. Ordinal

2. Nominal

3. Ratio

4. Interval

5. Ordinal

6. Nominal

7. Ratio

8. Interval

Level of measurement is used in assigning measurement to variables depending on their attributes.

There are basically four (4) levels of measurement (see image in the attachment):

1. <u>Nominal:</u> Here, values are assigned to variables just for naming and identification sake. It is also used for categorization.

  • Examples of variables that fall under the measurement are: Favorite movie, Eye Color.

<u>2. Ordinal:</u> This level of measurement show difference between variables and the direction of the difference. In order words, it shows magnitude or rank among variables.

  • Examples of such variables that fall under this are: highest degree conferred, birth order among siblings in a family.

<u>3. Interval Scale:</u> this third level of measurement shows magnitude, a known equal difference between variables can be ascertain. However, this type of measurement has <em>no true zero</em> point.

  • Examples of the variables that fall here include: Monthly temperatures, year of birth of college students

4. Ratio Scale: This scale of measurement has a "true zero". It also has every property of the interval scale.

  • Examples are: ages of children, volume of water used.

Therefore, the level of measurement of each given variable are:

1. Ordinal

2. Nominal

3. Ratio

4. Interval

5. Ordinal

6. Nominal

7. Ratio

8. Interval
