If point E is the midpoint of and point D is the midpoint of , which expression represents the value of s

The combination of two rays with the same terminal is called an angle. The vertex of the angle is the common terminal of the rays, which are referred to as the sides of the angle.

A ray is a segment of a line with one endpoint and an endlessly extending end. Two rays can be linked at their starting points to create an angle, and their other ends can stretch indefinitely.

According to the question,

the proportion of an angle's measurement to the width of its sides.

Therefore, an angle's measure is constant regardless of how far it is from its vertex.

Due to the fact that adjacent angles are two angles with a shared vertex, and side, but not interior points.

Therefore,

The combination of two rays with the same terminal is called an angle.

The vertex of the angle is the common terminal of the rays, which are referred to as the sides of the angle.

Hence the measure of an angle is the same at all distances from its vertex.

The graph on the bottom left represents the polynomial function

y =  -x⁴ + 6x³ + 11x² - 60x - 100.

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.

The relationships between two or more items are frequently represented by the points on a graph.

Given:

An equation,

y =  -x⁴ + 6x³ + 11x² - 60x - 100.

And one of the factors of the equation is (x-5).

That means, x = 5 is one of the roots of the equation.

From the given graphs,

we can eliminate top left graph and bottom right graph.

Because, the graphs of the equation do not touch the x-axis at x = 5.

Let x = -2,

Then,

y = -(-2)⁴ + 6(-2)³ + 11(-2)² - 60(-2) - 100.

y = -16 -48 + 44 + 120 - 100

y = 0

That means,

x = -2 is one of the roots of the equation.

Residual is the difference between the expected and actual y values, so r I = y I y i. A negative residual indicates that the anticipated value is excessively high, whereas a positive residual indicates that the projected value was excessively low. The goal of a regression line is to reduce the total amount of residuals.

What is Mcq, or salvage value?

When an item reaches the end of its useful life, its salvage value—or potential market value—is estimated. It can also be described as the asset's book value after depreciation has been taken into account.

What does the depreciation formula's residual value mean?

The asset's final worth is its residual value. To obtain the entire amount, it is therefore deducted from the starting value. Consequently, we are given the depreciation figure. This sum is divided by the usable years of the asset using the straight-line depreciation technique.

The equation x² - 4x + 3√2 = 0 has no real roots.

The roots of a quadratic equation are the values of variables satisfying the given quadratic equation.

There are three types of roots in quadratic equations, they are:

How many roots f(x) has can be seen from the discriminant's value : -

If b2 - 4ac > 0, the quadratic function has two unique real roots.

If b2 - 4ac = 0, then the quadratic function has one repeating real root.

If b2 - 4ac < 0, then the quadratic function has non-real roots.

Discriminant ; D = b² - 4ac

According to the given question, we have to find the nature of the roots of the equation, so finding the nature of the roots of all the equations separately

1.  x² - 4x + 3√2 = 0

Here, a = 1, b = -4 and c = 3√2

∵ D = b² - 4ac

∴ D = (-4)² - 4(1)(3√2)

⇒ D = 16 - 12√2

⇒ D = 16 - 12(1.414) = 16 - 16.968

∴ D = -0.968

⇒ D < 0

Consequently, there are no real roots in the equation.

2. x² + 4x - 3√2 = 0

Here, a = 1, b = 4 and c = -3√2

∵ D = b² - 4ac

∴ D = (4)² - 4(1)(-3√2)

⇒ D =  16 + 12√2 > 0

⇒ D > 0

As a result, the equation has two unique real roots.

3. x² + 5x + 3√2 = 0

Here, a = 1, b = 5 and c = 3√2

∵ D = b² - 4ac

∴ D = (5)² - 4(1)(3√2)

⇒ D = 25 - 12√2 = 8.029

⇒ D > 0

As a result, the equation has two unique real roots.

4. 3x² + 4√3x + 4 = 0

Here, a = 3, b = 4√3 and c = 4

∵ D = b² - 4ac

∴ D = (4√3)² - 4(3)(4)

⇒ D = 48 - 48 = 0

⇒ D = 0

As a result, the equation has two roots that are equal.

The measures of the three angles in a triangle is 84°, 30° and 66° respectively.

α + β + γ = 180° . From this, you can calculate the angles: ax, bx, and cx, as well as the unknown x. We translate these ideas into a detailed procedure for using ratios to locate missing angles in triangles in the following section.

The ratios are:

∠A = 14, ∠B = 5, ∠C = 11

Total ratio = 14 + 5 + 11= 30

The total angle in a triangle = 180°

So,

∠A= 14 / 30 × 180°= 0.46× 180°= 84°

∠B= 5/30 × 180°= 0.16 × 180°=30°

Mike's car will be worth £4116 at the start of 2017 as the car decreases in value by 30% every year

At the start of 2014, Mike's car is worth £12000,

we shall calculate the decreased worth of the same car to the start of 2017 as follows:

At the end of 2014, 30% of £12000 is calculated as;

£12000 × 30/100 = £3600

At the start of 2015, the car will be worth

£12000 - £3600 = £8400

At the end of 2015, 30% of £8400 is calculated as;

£8400 × 30/100 = £25200

At the start of 2016, the car will be worth

£8400 - £2520 = £5880

At the end of 2016, 30% of £5880 is calculated as;

£5880 × 30/100 = £1764

At the start of 2017, the car will be worth

What comprises an arithmetic series?

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6. An arithmetic progression is another name for an arithmetic sequence.

This sequence appears to be increasing by 6 each time, so it is an arithmetic sequence. The common difference is 6. The nth term of an arithmetic sequence is given by the formula:

an = a1 + (n-1)d

where a1 is the first term, d is the common difference and n is the position of the term in the sequence.

We can use this formula to find the 48th term of the sequence:

a48 = a1 + (48-1)d

a48 = 13 + (48-1)6

a48 = 13 + 47*6

a48 = 13 + 282

Answer:

x = 1, x = 5

Step-by-step explanation:

|x−7|=|2x−8|  ==> there are 2 ways to simplify this equation:

1. x - 7 = 2x - 8

2. -(x - 7) = 2x - 8

Let's first solve equation 1:

x - 7 = 2x - 8

-7 = x - 8  ==> subtract x on both sides

x - 8 + 8 = -7 + 8  ==> add 8 on both sides

x = 1  ==> simplify

Now let's solve equation 2:

-(x - 7) = 2x - 8

-x - (-7) = 2x - 8  ==> distribute the negative sign to x and -7

-x + 7 = 2x - 8  ==> subtracting a negative number is equivalent to adding a

                               positive number

7 = 3x - 8  ==> add x on both sides

15 = 3x ==> add 8 on both sides

x = 5 ==> divide 3 on both sides

Hence, the answers are x = 1 and x = 5.

A box plot, often known as a boxplot, is a method in descriptive statistics for graphically displaying the localization, spread, and skewness groups of numerical data through their quartiles. A box plot is a graphical representation of statistical data that uses the lowest, first quartile, median, third quartile, and maximum values. The name "box plot" refers to how the graph resembles a rectangle with lines extending from the top and bottom. Box and whisker plots, often known as box plots, are an excellent graphic for displaying the distribution of data points over a specified metric. These graphs show ranges within variables that have been measured. Outliers, the median, the mean, and where the majority of the data points fall inside the "box" are all included.

A 30-60-90 triangle is a special type of right triangle where the angles are 30 degrees, 60 degrees, and 90 degrees. The side opposite the 30 degree angle is called the "short leg", the side opposite the 60 degree angle is called the "medium leg", and the side opposite the 90 degree angle is called the "long leg".

The ratios of the sides in a 30-60-90 triangle are always in the proportion of 1 : √3 : 2 . To find the legs of a 30-60-90 triangle when given the long leg, you can use these ratios.

If the long leg is "x", then the short leg is x/2 and the medium leg is x*√3/2.

For example, if the long leg is 8 cm, you can use these ratios to find the short leg and medium leg:

The short leg is 8 cm / 2 = 4 cm

The medium leg is 8 cm * √3 / 2 = 4 * √3 cm = 4 * 1.732 cm = 6.928 cm (approx)

So, in this example, the short leg is 4cm and the medium leg is 6.928cm (approx).
