The height of the actual glass is equal to 10 cm.

In Geometry, a scale factor is the ratio of two corresponding side lengths or diameter in two similar geometric figures such as drinking glasses, which can be used to either horizontally or vertically enlarge (increase) or reduce (decrease or compress) a function that represents their size.

Mathematically, the scale factor of a geometric figure can be calculated by dividing the dimension of the image by the dimension of the pre-image (original figure):

Scale factor = Dimension of image (new figure)/Dimension of pre-image(original figure)

Scale factor = 2/2.5

For the height of the actual glass, we have:

2/2.5 = 8/x

x = (2.5 × 8)/2

x = 20/2

x = 10 cm.

Circle M has a center (h+d, k+e) and the radius is rs. Therefore, option C is the correct answer.

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Given that, circle B has a center (h, k) and a raius of r. Circle B is translated d units to the right and e units up. Then it is dilated about its new center by a scale factor s resulting in a new circle

Translation rules:

When the shape is moved towards the right by k units, then replace x with x + k.

When the shape is moved up by k units, then replace y with y + k.

Now, (h, k)→(h+d, k+e) and the radius is rs.

Answer: The graph that could be the graph of f(x) is a parabola that opens upwards, with a vertex at (2,-4) and x-intercepts at x = -1 and x = 4. Since the degree of the polynomial function f(x) is 3 and the roots are -1, 0, and 4, the polynomial function is a cubic function and its graph is a parabola.

The roots of a polynomial function are the x-coordinates of the x-intercepts of the graph of the function. Therefore, since the roots of the equation f(x) = 0 are -1, 0, and 4, the graph of f(x) will have x-intercepts at x = -1 and x = 4.

The fact that the vertex is at (2, -4) mean that the parabola will open upwards and pass through the point (2, -4)

It's important to note that, if the polynomial function has a degree greater than 3, there may be multiple graphs that could represent the polynomial function, as long as they have the same roots.

Yes, it is possible to order a list of numbers by their number of words. To do this, you will need to count the number of words in each number, then order them in ascending or descending order based on this number.

Here is an example of how to do this:

1. Count the number of words in each number. For example, the number “twenty-nine” has two words (“twenty” and “nine”).

2. Order the numbers from least to greatest or greatest to least based on the number of words. For example, “nine” has one word, so it would come before “twenty-nine” which has two words.

3. Place the numbers in order from least to greatest or greatest to least.

This method can also be used to order numbers that are written in words or numbers that are written in numerals. However, if the numbers are written in numerals, you will need to convert them to words before you can count the number of words.

The given number lies between 64 and 81

A value that, when multiplied by itself, equals the original number is said to be the square root of a number. The character "√" stands for it. For instance, since 4 × 4 is 16, the square root of 16 is 4. Although a number's square root can be positive or negative, the positive value is more frequently utilized. To determine a distance or length, it is also used in mathematics.

given that square root is approximately 8.1066

let the value of the number be x

so √x>8 and √x<9

=>     8 < √x < 9

squaring on the both side we get

64 < x < 81

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total salary of Saul be represented as A

Now , the equation will be

The basic monthly salary of Saul = $ 1,500

The total commission percentage of Saul = 4 %

The minimum amount of items to sell = $ 20,000

The amount of items worth sold = $ 26,000

So , the extra amount of items sold by Saul = 26,000 - 20,000 = $ 6,000

Now ,

The total salary of Saul A = basic monthly salary of Saul + ( commission percentage x extra amount of items sold by Saul )

An isosceles right triangle has a right angle (90 degrees) and two congruent acute angles(45 degrees).

A triangle's isosceles quality is characterised by its two equal-length sides. The third side which is not equally long as the first two is referred to as the base. The legs are the two equal sides. The vertex opposite the base has an obtuse, acute, or straight angle, and the angles at that vertex are congruent.

A right angle of 90 degrees and two congruent acute angles make up an isosceles right triangle (45 degrees). A right triangle has three angles, two of which are acute and one of which is always a right angle (90 degrees). Because the two legs of an isosceles right triangle are congruent, the two acute angles are likewise congruent. An isosceles right triangle, therefore, has angles of 90 degrees, 45 degrees, and 45 degrees.

Answer:

  75.5°

Step-by-step explanation:

You want the angle between a 50 pound force and a 75 pound force given that their resultant is a 100 pound force. Force 1 is aligned with the +x axis, and Force 2 is in the first quadrant.

The forces and their resultant form a triangle such that the angle opposite the resultant is the supplement of the angle between the forces. We can find the angle opposite the resultant using the law of cosines:

  c² = a² +b² -2ab·cos(C)

  cos(C) = (a² +b² -c²)/(2ab)

  C = arccos(a² +b² -c²)/(2ab) = arccos((50² +75² -100²)/(2·50·75))

  C = arccos(-1875/7500) = arccos(-1/4) ≈ 104.48°

The angle between the vectors is the supplement of this:

  angle12 = 180° -104.48° = 75.52° ≈ 75.5°

The angle between the forces is about 75.5°.

  (x, y) = (2, 4)

Step-by-step explanation:

You want to solve the system of equations ...

There are numerous ways to solve this system of equations. One of the simplest is to use a graphing calculator. (See the attachment)

  (x, y) = (2, 4)

The second equation gives an expression for x that can be substituted into the first equation:

  y = -2(y -2) +8

  3y = 12 . . . . . . . . add 2y and simplify

  y = 4

  4-2 = x = 2

The solution is (x, y) = (2, 4).

The y-variable has a coefficient of 1 on the left side of the equal sign, so we can eliminate the y-variable by subtracting the second equation from the first.

  (y) -(y -2) = (-2x+8) -(x)

  2 = -3x +8 . . . . . . . . . . . simplify

  3x = 6 . . . . . . . . . . add 3x-2

  x = 2 . . . . . . . . divide by 3

  y = -2(2) +8 = 4 . . . . . substitute for x in the first equation

The solution is (x, y) = (2, 4).

Sublimation is the straight transition from a solid state of materials to a vapor state upon heating (without becoming liquid).

When a substance changes from one state to another, as as from a solid to a gas, this transition, transformation, or conversion is referred to as sublimation.

Sublimation is the procedure through which a material is converted from its solid to gaseous phase without moving to its liquid form. At a temperature and pressure below the substance's triple point, this process, an endothermic phase transition, takes place. The opposite of this process, in which a gas is transformed straight into a solid state, is desublimation or deposition.

An inequality in math is a statement that compares two values using an inequality sign. Inequalities can be used to describe a range of values, such as greater than, less than, greater than or equal to, and less than or equal to.

For example, the inequality 7 > 5 states that the value 7 is greater than the value 5. This type of inequality is known as a strict inequality, meaning that the values must be greater or less than one another in order for the statement to be true.

Another type of inequality is a non-strict inequality, which uses the symbols “≥” and “≤”. Here, "greater than or equal to" and "less than or equal to" are the appropriate definitions. For example, the inequality 5 ≤ 7 states that the value 5 is less than or equal to the value 7. This type of inequality allows the values to be equal to each other, rather than just strictly less or greater than one another.

Inequalities are used in a variety of mathematical equations, including linear equations, quadratic equations, and polynomial equations. They can also be used to solve for unknown values, such as the solution to an equation. Inequalities are also used to describe ranges of values, such as the range of numbers on a number line.
