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 value of x when y = 1000 is 8.59.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

y = 1.7952 x [tex]2.0657^x[/tex]

Substitute y = 1000

1000 = 1.7952 x [tex]2.0657^x[/tex]

10³ = 1.7952 x [tex]2.0657^x[/tex]

Taking logs on both sides.

log 10³ = log (1.7952 x [tex]2.0657^x[/tex])

3 log 10 = log 1.7952 + x log 2.0657

3 x 1 = 0.25 + 0.32x

3 = 0.25 + 0.32x

0.32x = 3 - 0.25

x = 2.75/0.32

x = 8.59

Thus,

The value of x is 8.59.

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

£5880 - £1764 = £4116

Answer:

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).

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

a48 = 295

A dilation happens when the coordinates of the vertices of an image are multiplied by the scale factor, changing the side lengths of a figure.

For this problem, we want for the dimensions of the updated stage to be half the dimensions of the original stage, hence the scale factor of the dilation is given as follows:

Step-by-step explanation:

The equation and diameter CD of the parabola are x=1/10 y^2and 2√110

In this question we have four case of parabolas with vertical axes of reference, whose standard formula is:

a(x – h)2 + k

Where:(h, k) - The vertex of the parabola.

a - Least distance between the vertex and the focus of the parabola.

Please notice that p < 0 when the directrix is above the focus, otherwise p < 0. The vertex is the midpoint of line segment between the directrix and the focus.

Given;

Vertex is at origins (0,0) and latus rectum = 10 and the graph open right so a is positive and the equation is:

x=a (y-k)^2+h.

To write the equation we need to find a using the latus rectum equation.

We substitute the values.Then inverse place of a with 10

Latus rectum=|1/a|                

10=|1/a|                              

a=1/10

The equation:

x=a (y-k)^2+h                      

x=1/10(y-0)^2+0

x=1/10 y^2

-Assume the distance between C and the center is EC. If E is (11,0) and C is (11, y).

-EC=y

-The equation of the parabola is x=1/10 y^2

Now, Substitute the value of C coordinate, which

x=1/10 y^2                          

Substitute the value of C coordinate, which is (11, y).

11×10=1/(10×10) y^2    

√(y^2 )=√110                

y=EC=√110

Because the distance of EC = ED

CD=EC×2                                  

CD=√110×2

CD=2√110

Therefore, the equation of parabola and CD will be x=1/10 y^2 and 2√110

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.

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°

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 interval over which f(x) = x² - x - 1 has an average rate of change of zero is (1/2, 1/2) as it is the only point at which the average rate of change is zero.

An average rate of change of zero means that the function is not increasing or decreasing over the interval in question. To find the interval over which f(x) has an average rate of change of zero, we need to find the critical points of the function. A critical point is a point at which the function's derivative is equal to zero or is undefined.

The derivative of f(x) = x² - x - 1 is:

f'(x) = 2x - 1

Setting f'(x) = 0, we get:

2x - 1 = 0

Solving for x, we get:

x = 1/2

Since this is the only critical point of the function, it is the point where the function has an average rate of change of zero. To determine the interval, we need to check the sign of the function's derivative on either side of the critical point.

f''(x) = 2 > 0

So x = 1/2 is the minima of the function

f'(x) = 2(1/2) - 1 = 0, at x = 1/2

so f'(x) > 0 for x < 1/2 and f'(x) < 0 for x > 1/2

Therefore the interval over which f(x) has an average rate of change of zero is (1/2, 1/2) or {1/2}.
