The parent function of the function y =  2x² - 6 is y = x². The explanation about transformation is given.

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.

We have the quadratic function,

y = 2x² - 6

To find the parent function:

Add

y(x) = 2x²

Divide by 2

y(x') = x²

If there is a horizontal or vertical shift, reflection around the x-axis or y-axis, or vertical stretch, the transformation may be found by comparing the equation to the parent function.

Parent Function:

y = x²

Horizontal Shift: None

Vertical Shift: Down 6 Units

Reflection about the x-axis: None

Reflection about the y-axis: None

Vertical Compression or Stretch: Stretched

Therefore, the parent function is y =  x².

The length of the side is 10√2 cm.

To solve this problem we need to know the concepts of area of plane figures.

We know the  area of a square is the square of its sides.

Now, the given data says that the area of a square game board is 200  sq.cm.

Let the side of the square be a cm.

According to question,

    a × a=200

⇒ a² = 200

⇒ a = √200

∴ a = 10√2 cm

So, the length of one side of the square game board is  10√2 cm.

For this particular problem (with units in mind), the formula for arc length is

Arc length

,

Where

x

is the central angle measure and

r

is the radius of the circle.

You don't really have to work too hard to remember this formula. The arc length formula is easy to remember because it is just the circumference of the circle times the central angle over

360

∘

.

Anyway, let's continue with the problem. We are given that the central angle is

60

, and that

r

, our radius, is

Step-by-step explanation:

The measure of the angle 1 is 95.05 degrees.

It is given in the question that:-

Measure of Angle 1 = 7x + 10

Measure of Angle 2 = 3x + 4

Measure of Angle 3 = 3x + 8

All the angles are supplementary.

We know that, the sum of all the supplementary angles is equal to 180 degrees.

Hence, we can write,

(7x + 10) + (3x + 4) + (3x + 8) = 180

(7x + 3x + 3x) + (10 + 4 + 8) = 180

13x + 22 = 180

13x = 180 - 22

13x = 158 degrees

x = 158/13 degrees

x = 12.15 degrees (rounded off  to the hundredths place )

Hence,

Measure of angle 1 = 7x + 10 = 7(12.15) + 10 = 85.05 + 10 = 95.05 degrees.

By dimensional analysis and the conversion factor between feet and yards, we find that a square yard is equal to a quantity of 3² square yard, that is, a quantity of 9 square feet. (Correct choice: C)

In accordance to dimensional analysis, area units are equal to the square of length units, that is, length unit multiplied by length unit. That is:

[A] = [L] × [L] = [L]²

Where:

L - Length unit

A - Area unit

If a yard is equal to a quantity of three feet, both length units, then a square yard is equal to a quantity of 3² square feet, that is, a quantity of 9 square feet, both area units. Therefore, we can construct the following conversion factor:

The price of the file is Rs 89.18  and pen is Rs 109.43 as calculated from a linear equation .

An equation is said to be a linear equation if the maximum power of the variable is consistently 1.

Let us consider the cost of the file be x dollars.

Then cost of the pen = x + 20.25

And cost of the book = x + 20.25 - 13.20 = x - 7.05

The cost of all three items together is 280.75

Now we will form a linear equation in x to find the cost of each of the pen, book and file separately.

x + x + 20.25 + x - 7.05 = 280.75

or, 3x + 13.20 = 280.75

or, 3x = 267.55

or, x = 89.18

Hence the cost of the file is approximately Rs 89.18

Cost of the pen = 89.18 + 20.25 = Rs 109.43

Cost of the book =  x - 7.05 = 89.18 - 7.05 = Rs 82.13

A fraction, which derives from the Latin word fractus, which means "broken," is a portion of a whole or, more broadly, any number of equal pieces. A fraction in spoken English refers to the number of components of a particular size.

A fraction consists of a numerator and a denominator. The numerator divided by the denominator is known as a fraction.

Compound fractions, complicated fractions, and mixed numeral fractions are examples of uncommon fractions that use numerators and denominators.
