The axis of symmetry for the function f(x) is x = 8 , and h(x) is x = 3

The axis of symmetry is a hypothetical straight line that splits a form into two identical halves, making one half the mirror image of the other. Both pieces are overlaid when folded along the axis of symmetry.

A straight line called the axis of symmetry is what gives an object its symmetrical form and exactly the same reflections are produced on each side of the axis of symmetry on the graph.

From the given information:

f(x) = -4(x - 8)² + 3

Use the vertex form, y = a ( x − h )² + k, to determine the values of a, h, and k.

Since the value of a is negative, the parabola opens down, and the vertex (h, k) is (8, 3).

The distance (p) from the vertex and the focus of the quadratic equation can be calculated by using the formula:

P = 1/4a

Replacing the value of a from above:
P = 1/4(-4)

P = -1/16

The focus of a parabola can be determined by adding the p to the y-coordinate k if the parabola opens up or down. Thus, (h, k + p) = (8, 47/16).

Thus, the axis of symmetry is finally estimated by finding the line that passes through the vertex and the focus;

Axis of symmetry x = 8

For the graphical function of h(x); we use the following points on the graph to determine the equation of the parabola: (1,-2), (3,2), (5,-2)

Thus, h(x) = -x² + 6x - 7

Rewriting the function in its vertex form, we have:

y = - (x - 3)² + 2

Using the vertex form;

The vertex (h,k) = (3,2). The axis of symmetry (x) is the line that passes through the vertex and the focus, x = 3.

The other way of representing the given function is f(x) = 2 - 8/(x+4).

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Given, rational function f(x)=2x/x+4

Using Long division:

x + 4) 2x      ( 2

         2x + 8

-------------------------

                -8

The remainder is -8.

Since the Degree of the remainder is less than the degree of the divisor then we are done.

Now using,

Dividend = divisor* quotient + remainder

=> 2x = 2 * (x+4) -8

The Cartesian, or rectangular, coordinate system is composed of an x-axis that runs horizontally and a y-axis that goes vertically.

The rectangular coordinate system of the Cartesian plane, which bears Rene Descartes' (1596–1650) name, assigns each point in the plane a pair of integers.

An x-axis that runs horizontally and a y-axis that runs vertically make up the Cartesian, or rectangular, coordinate system. The origin is the place where the two axes meet. Any point can be characterized by its distance from the origin along the x-axis and along the y-axis, and this distance is represented by the symbol (x, y).

A two-dimensional coordinate plane produced by the intersection of the x- and y-axes is known as the cartesian plane in mathematics. At the location known as the origin, the x- and y-axes cross perpendicularly.

Circle Detection Algorithm is a highly efficient and effective solution to finding the most number of points that lie on any one circle in a 2D real plane.

The algorithm to solve this problem is known as the "Circle Detection Algorithm." This algorithm starts by considering three points randomly selected from the given N points.

Next, the algorithm checks the number of points that lie on this circle. If this number is greater than the current maximum, then this circle becomes the new candidate for the circle that contains the most number of points.

To ensure that the algorithm is efficient, it is important to choose the points randomly, as this reduces the chances of getting stuck in a local maximum.

The mathematical formula to calculate the center and radius of the circle that passes through three points (x₁, y₁), (x₂, y₂), and (x₃, y₃) is given by:

x = ( (y₂ - y₁)(y₃² - y₁² + x₃² - x₁²) - (y₃ - y₁)(y₂² - y₁² + x₂² - x₁²) ) / (2 * (x₃ - x₁)(y₂ -y₁) - 2 * (x₂ - x₁)(y₃ - y₁) )

y = ( (x₂ - x₁)(x₃² - x₁² + y₃² - y₁²) - (x₃ - x₁)(x₂² - x₁² + y₂² - y₁²) ) / (2 * (y₃ - y₁)(x₂ -x₁) - 2 * (y₂ - y₁)(x₃ - x₁) )

r = √(x₁ - x)² + (y₁ - y)²

Once the center and radius have been calculated, the algorithm can easily check the number of points that lie on the circle by calculating the distance of each point from the center and checking if it is equal to the radius.

The probability of not rolling doubles on one roll of two fair six-sided dice is 5/6.

Hence, the probability of rolling doubles is 1/6. The probability of not rolling doubles in three rolls is (5/6)^3. So, the probability of rolling doubles on the third roll is 1 - (5/6)^3. This is the same as (1/6) (5/6)^2. So the correct answer is (d) (1/6) (5/6)^2.

The probability of rolling a specific number on one fair six-sided die is 1/6.

In this problem, we are looking for the probability of rolling doubles (i.e. getting the same number on both dice) in three rolls.

The probability of not rolling doubles in one roll is 5/6 (since there are five outcomes that are not doubles, out of a total of 6 possible outcomes).

The probability of not rolling doubles in three rolls is (5/6)^3, which represents the chance of not rolling doubles in three independent rolls, each with a 5/6 probability of not rolling doubles.

To find the probability of rolling doubles in three rolls, we subtract the probability of not rolling doubles in three rolls from 1:

P(rolling doubles in three rolls) = 1 - (5/6)^3 = (1/6) (5/6)^2

So, the correct answer is (d) (1/6) (5/6)^2.

Step-by-step explanation:

The maximum number of boxes that can fit in the trailer can be calculated by dividing the volume of the trailer by the volume of each box.

First, we need to convert the dimensions of the boxes and the trailer to the same unit, such as cubic feet. The volume of each box is given by:

V_box = (1 1/2 ft)^3 = (1.5 ft)^3 = 3.375 ft^3

Next, we calculate the volume of the trailer:

V_trailer = 28 ft * 8 1/2 ft * 9 1/6 ft = 2070 ft^3

Finally, we divide the volume of the trailer by the volume of each box to find the maximum number of boxes:

N_boxes = V_trailer / V_box = 2070 ft^3 / 3.375 ft^3 = 614.07 boxes

Since we can only fit whole boxes in the trailer, the maximum number of boxes that will fit is 614.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, A department store has marked down its merchandise by 25%. It later decreases by $5 the price of items that have not sold.

Let, 'x' be the price of the merchandise.

So, After adding 80% to its cost it becomes [(100 + 80)/100]×x = 1.8x.

Later it decreases by 25% the price of items that don't sell quickly.

So, It has a value of (75/100)×1.8x = 1.35x.

a. A function f(x) to represent the price after the 80% markup is.

f(x) = 1.8x.

b. A function g(x) to represent the price after the 25% markdown is,

f(x) = 1.35x.

c. A composition function to find the price of an item after both price adjustments that originally the boutique $150 is,

f(150) = 1.35×150.

f(150) = 202.5.

d. Let, The price of the item be $100, after 80% makeup it would be

$180 and after 25% markdown it would be $135.

If there is no solution to the system of equations, it signifies that the equations describe two parallel lines in the two-dimensional plane. This indicates that the lines will never meet because they have the same slope but separate y-intercepts. This signifies that the two lines are geometrically distinct and will never intersect.

A geometric significance is a geometric aspect or quality of a form or item. This encompasses the object's size and orientation, as well as its symmetry and proportions. Several areas, including architecture, engineering, graphic design, and mathematics, rely on geometric importance. In architecture, for example, the size and direction of a structure may be utilised to decide how much light it receives and how much shade it casts. The geometry of an item can be used to determine its strength, stiffness, and durability in engineering. The symmetry and dimensions of an object may be employed in graphic design to produce an appealing and balanced design.

The given question states that when there are no solutions to a system of K equations in two variables, it means that the lines associated with those equations are either parallel or coincident. Geometrically, this means that the lines are not intersecting, which implies that the two variables cannot simultaneously satisfy all of the equations.

Answer: 400 ft

Step-by-step explanation:

Since the triangles are Congruent Triangles (similar)

x/40  =  50/5

Cross multiply

5x = 2000

divide both sides by 5

5x/5 = 2000/5

x = 400 ft
