In order in which the boxes appear:

[tex]\boxed{a\sqrt{2}}[/tex]

[tex]\boxed{a\sqrt{2}}[/tex]

[tex]\boxed{a\sqrt{2}}[/tex]

Step-by-step explanation:

At any coordinate (x , y) the distance from the origin (0, 0) is computed by the distance (Pythagorean formula) as:

d = [tex]\sqrt{x^2+y^2}[/tex]

Since x = y = a for both ants, the distance is

[tex]d = \sqrt{a^2+a^2}\\\\d = \sqrt{2a^2}\\\\d = \sqrt{a^2}\cdot \sqrt{2}\\\\d = a\sqrt{2}[/tex]

It does not matter whether both coordinates are positive or both negative since we are taking the squares of the coordinates and distance is always positive

If a is a set of real numbers that is bounded above and b is a set of real numbers that is bounded below, there is at most one real number that can exist in both sets.

A real number is any number that can be expressed as a decimal or fraction and exists on the number line.

If a set of real numbers, represented by a, is bounded above, it means that there exists a real number, represented by M, such that all the numbers in the set are less than or equal to M. Similarly, if a set of real numbers, represented by b, is bounded below, it means that there exists a real number, represented by m, such that all the numbers in the set are greater than or equal to m.

Now, let's consider a real number, represented by x, that exists in both sets a and b. If x exists in a, it must be less than or equal to M and if x exists in b, it must be greater than or equal to m. Hence, x must satisfy both conditions: M >= x >= m.

From these conditions, it can be deduced that M and m must be equal to x. In other words, there can only be one real number that is simultaneously the greatest value in a and the smallest value in b.

The probability of drawing two blue card is 1/16

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.

Probability = sample space / total outcome

The total number of cards = 12

number of blue cards = 3

Probability of drawing blue card = 3/12

= 1/4

Since the blue card is replaced,

the probability to draw blue card in the second draw is 3/12 = 1/4

probability of drawing two blue cards = 1/4× 1/4

The advantages of bar charts over pie charts while graphing the given data are discussed below.

A bar chart or bar graph is a visual representation of categorical data that uses rectangular bars with heights or lengths proportional to the values they represent. The possibility of a bar plot, both vertical and horizontal, exists. Vertical bar graphs are also referred to as column charts.

A circular statistical image known as a pie chart uses slices to represent numerical proportions. Each slice's arc length in a pie chart varies depending on the amount it represents.

Any numbers can be chosen for the numeric value axis in a bar chart.

Pie charts can only be used if the sum of the various parts equals a meaningful whole because they are intended to illustrate how each portion contributes to the whole.

Hence bar chart is more advantageous over pie chart when more information is to be presented through charts.

The restriction on the variable for the given equation is x ≠ 0

A restricted variable is a variable whose values are confined to some only of those of which it is capable.

Given is an equation, -3/x + 8 = 3/4,

In the given equation, -3/x + 8 = 3/4

We see that, x is in denominator, therefore, x ≠ 0,

Therefore, the restriction is x ≠ 0

Finding the value of x,

-3/x + 8 = 3/4

-3/x = 3/4 - 8

-3/x = -29/4

3/x = 29/4

x/3 = 4/29

x = 12/29

Answer: x = 15

Step-by-step explanation:

Use the Pythagorean theorem

The factors of the quadratic function  p(x) is equal to

(x + 5 + √(65)/2)(x - 5 + √(65)/2).

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, The zeros of the quadratic function p(x) = x² - 5x - 10 are,

(5 + √(65)/2, 5 - √(65)/2).

Therefore, The factors of p(x) = [x + (5 + √(65)/2)][x + (5 - √(65)/2)]

p(x) = (x + 5 + √(65)/2)(x - 5 + √(65)/2).

The height of the school is given by the equation H = 13.274 m

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the height of the building be represented as ED = H

Let the distance of mirror from the building be CD = 11.15 m

The distance walked extra from the mirror CB = 1.05 m

The distance of Fawzia's eyes to the ground AB = 1.25 m

Now , let the triangles be represented as ΔABC and ΔCED ,

where both the triangles are similar and have a common angle

So , the corresponding sides of similar triangles are in the same ratio

And , ED / AB = CD / CB

Substituting the values in the equation , we get

ED / 1.25 = 11.15 / 1.05

Multiplying by 1.25 on both sides of the equation , we get

The height of the school building ED = ( 11.15 x 1.25 ) / 1.05

On simplifying the equation , we get

Answer:

  A.  1008 square inches

Step-by-step explanation:

You want the lateral area of a triangular prism with base edge lengths 10 in, 10 in, and 8 in, and a height of 36 in.

The lateral area of the prism is the area of the three rectangular sides. The area of each rectangle is the product of its length and width. All have the same length, so we can sum the widths before multiplying:

  LA = Pl

  LA = (10 in + 10 in + 8 in)(36 in) = 28·36 in² = 1008 in²

The lateral surface area of the prism is 1008 square inches.

Alright to solve this problem, we can simply take the total gallons of paint Isaiah has and divide that by 1/3

So 6 divided by 1/3 should give us the answer.

But how do we divide fractions? Remember this useful tip for all throughout your school life when you don't have a calculator: Keep, Change, Flip

Keep the first fraction, change the sign to a multiplication sign, and flip the second fraction.

The general form of the equation of a hyperbola can be determined from the given information. The vertices of the hyperbola are given as (-2, 5) and (6, 5). The foci of the hyperbola are given as (-3, 5) and (7, 5). The first step in finding the equation of the hyperbola is to determine the center of the hyperbola. The center of the hyperbola can be calculated by taking the average of the x-coordinates of the vertices and then the average of the y-coordinates of the vertices. The center of the hyperbola is then (2, 5). The distance between the foci of the hyperbola is 4. This distance can be calculated by subtracting the x-coordinates of the foci and then subtracting the y-coordinates of the foci. The standard equation for a hyperbola can then be formed by substituting the center coordinates and the distance between the foci into the equation.

The domain of f(g(x)) is the set of all real numbers x for which g(x) is defined and lies in the domain of f(x).

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

Given f(x) = 1/(x + 1) and g(x) = 1/(x+2)

First, let's find the domain of g(x). The function g(x) = 1/(x+2), so the denominator of this fraction must be non-zero. This means that x + 2 must be non-zero, or x must not equal -2. Thus, the domain of g(x) is all real numbers except for x = -2.

Next, let's find the domain of f(x). The function f(x) = 1/(x + 1), so the denominator of this fraction must also be non-zero. This means that x + 1 must be non-zero, or x must not equal -1. Thus, the domain of f(x) is all real numbers except for x = -1.

So, for f(g(x)) to be defined, g(x) must be in the domain of f(x), or g(x) must not equal -1. Since g(x) = 1/(x+2), this means that x + 2 must not equal 0, or x must not equal -2.

Combining these two conditions, the domain of f(g(x)) is all real numbers except for x = -2 and x = -1.

Therefore, the domain of f(g(x)) is all real numbers except for x = -2 and x = -1.
