An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively.

What is an angle?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves.

Angle can also refer to the length of a rotation or an angle. This metric represents the relationship between a circular arc's length and radius. The arc is centered at the vertex and defined by the sides in the case of a geometric angle. When there is a rotation, the arc is defined by any other point and the rotation's image, and it is centered at the rotation's center.

what transformations take f(x) = 3x+1 to g(x) = −3x−5 ?

Answers

The transformation that took f(x) = 3x+1 to g(x) = −3x−5 is reflection and translation 4 units downwards

How to find the transformations

given data

f(x) = 3x+1

g(x) = −3x−5

Reflection

Reflections changes the sign of the both coordinates

from                                      to

f(x) = 3x + 1                          f'(x) = -3x - 1

Answer:

Either of ...

reflection across the y-axis, and translation down 6reflection across the x-axis and translation down 4

Step-by-step explanation:

You want the transformations that take f(x) = 3x+1 to g(x) = -3x-5.

Transformation

The x-term of the transformed function has a sign opposite that of the original function. That can be accomplished by either of (a) reflection across the y-axis (replaces x by -x), or by (b) reflection across the x-axis (replaces f(x) by -f(x)).

Either way, an additional translation is required. That translation can be either vertical or horizontal, and may be done either before or after the reflection.

Horizontal reflection

Reflecting f(x) across the y-axis means it becomes ...

  f(-x) = 3(-x) +1 = -3x +1

In order to make that into -3x-5, we must add -6 to the function value:

  g(x) = f(-x) -6 = (3(-x)+1) -6 = -3x -5

F(x) will be taken to g(x) = -3x-5 by reflection across the y-axis and translation down 6 units.

Vertical reflection

Reflecting f(x) across the x-axis means it becomes ...

  -f(x) = -(3x +1) = -3x -1

In order to make that into -3x-5, we must add -4 to the function value:

  g(x) = -f(x) -4 = -(3x +1) -4 = -3x -5

F(x) will be taken to g(x) = -3x-5 by reflection across the x-axis and translation down 4 units.

__

Additional comment

As noted above, the translation can be either horizontal or vertical. For example, translating the function 2 units to the right makes it f(x-2). Then reflection across the y-axis replaces x by -x, so we have ...

  g(x) = f(-x-2) = 3(-x-2)+1 = -3x -6 +1 = -3x -5

To get g(x), we could translate right 2 units, then reflect across the y-axis.

We also note that point (-1, -2) is shared by f(x) and g(x), so reflection horizontally across the line x=-1, or vertically across the line y=-2 would also give the required transformation.

What is equivalent ratio?

When we compare any two kinds of ratios, they are said to be equivalent. To determine whether these two or more ratios are equivalent, they can also be compared to one another. For instance, the ratios 1:2 and 2:4 can be called as equivalent.

Describe ratio

Simply put, a ratio is a comparison of two numbers. When a ratio is equal, the proportionate relationship remains constant. By multiplying the first value by the same ratio, or unit of proportion, you can determine your own equivalent ratios.

Which ratio is equivalent?

It is possible to treat an equivalent ratio and a proportion interchangeably. An equivalent ratio is the result of simplifying the two ratios to the same fraction.

Let us take the value of x -----> the number of diamonds

Let us take the value of y ----> the number of chandeliers

Answers

The equations will be a+ y ≤ 13, since Micaela can't work more than 13 hours and also she needs to earn at least $140 each week, so other equation will be 13a + 10y ≥ 140.

What is inequalities?

Inequality, a declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.

a = number of hours spent tutoring

y = number of hours spent landscaping

Micaela can't work more than 13 hours, so a + y ≤ 13.

Also, she needs to earn at least $140 each week, so 13a + 10y ≥ 140.

Using intercepts, you may graph things in this format on paper. They must be transformed into slope-intercept form in order to be graphed on a standard graphing calculator.

For instance, if a = 12 and y = 2, then a + y = 13 hours, and 12(13) + 2(10) = $176. Micaela puts in her maximum number of hours and earns more than she should.

By applying the elimination method, solve the following pair of simultaneous equations:
− 2 = 4
4 + 2 = 6

Answers

By applying the elimination method the value of x is - 2 and y is 7.

This is a problem from algebraic equations and we have to apply the elimination method. We can solve this problem by following a few steps.

So, the given equation according to the question is,

− 2x = 4 ................ ( equation 1 )

4x + 2y = 6 ............... ( equation 2 )

While applying the elimination method we have to multiply equation (1) with the positive coefficient of x in the second equation and vice versa.

Here the coefficient of x in the first equation is 2 and in the second equation is 4.

Now, we have to multiply equation ( 1 ) with 4 and equation ( 2 ) with 2.

Therefore,

− 2x = 4 ................ ( equation 1 ) × 4

4x + 2y = 6 ............... ( equation 2 ) × 2

Now, we can rewrite the equations as,

− 8x = 16 .................. ( equation 3 )

8x + 4y = 12 .................. ( equation 4 )

Now the coefficient of x in both equations are same but opposite sign. So, we have to add the equations.

Here we get , -8x + 8x + 4y = 16 + 12

Or, 4y = 28

Or, y = 7

Now, we have to put the value of y in any equation.

4x + 2.7 = 6  ( equation 2 )

Or, 4x = 6 - 14 = -8

Or, x = -2

A standard die is rolled. Find the probability that the number rolled is odd.

Answers

Answer

Explanation

To determine the probability that the number rolled is odd using a standard die, we first list the total outcomes as shown below:

1,2,3,4,5,6

As we can see, the odd numbers are:

1,3,5

This means that the total favorable outcomes is 3.

Now, we use the formula:

[tex]Probability=\frac{favorable\text{ outcomes}}{Total\text{ outcomes}}[/tex]

We plug in what we know:

[tex]\begin{gathered} Probab\imaginaryI l\imaginaryI ty=\frac{favorable\text{ outcomes}}{Total\text{ outcomes}} \\ =\frac{3}{6} \\ Simplify \\ Probab\mathrm{i}l\mathrm{i}ty=\frac{1}{2} \end{gathered}[/tex]

Therefore, the probability that the number rolled is odd is 1/2.

Answer:

3/6

A standard die has 6 sides, numbered 1 through 6 (1,2,3,4,5,6). That means we have 3 odd numbers (1,3,5)  and 3 even numbers (2,4,6).

The total possible outcomes of an odd number are 3, because there are 3 odd numbers, and the total outcomes are 6. So we write it as 3/6, like 3 out of six chances of getting an odd number.

It can be simplified to 1/2.
