Answer:

[tex]x(20-2x)(25-2x)[/tex]

Step-by-step explanation:

The length removed from each side is [tex]2x[/tex].

So, the length and width of the box are [tex]25-2x[/tex] and [tex]20-2x[/tex].

The height of the box is [tex]x[/tex], so the volume is [tex]x(20-2x)(25-2x)[/tex].

Step-by-step explanation:

The volume of the pyramid with a base area of s² and the height s is [tex]\frac{1}{3} s^{2}[/tex]

The formula for calculating the volume of a square based pyramid is expressed as:

Since it is a square-based pyramid, the base area is calculated as:

Base Area = s²

If the height of the pyramid is equal to of the length of a side on the base, hence h = s

Substituting the base area and the height into the formula for the volume, this will give us;

[tex]V=\frac{BH}{3} \\V=\frac{s^{2}Xs }{3} \\V=\frac{s^{3} }{3} \\V=\frac{1}{3 } s^{2} \\[/tex]

Hence the volume of the pyramid with a base area of s² and the height s is [tex]\frac{1}{3}s^{3}[/tex]

The 4 functions of a stem are fruits, flowers, leaves, and branches.

In plants, a stem's primary role is to aid in the transfer of water and minerals from the roots to the leaves and other sections of the plant. Additionally, it supports the buds, leaves, flowers, fruits, and branches of plants.

In a plant, a stem does the following tasks:

(i) It holds up the fruits, flowers, leaves, and branches.

(ii) It moves water and minerals from a plant's roots to its leaves and other areas.

(iii) It transports nourishment from the leaves to various plant sections.

The larger number is 8 and the smaller number is -4.

Let us assume that the larger number is x and the smaller number is y.

Now according to the question:

The sum of two numbers is 4, so

x+y= 4....(1)

A two-variable linear equation has two variables and can be represented as: ax+by=c

Here x and y are the variables, a and b are the respective cofficients of the variables and c is a constant term.

And the larger number is 12 more than three times the smaller number.

So

x=y+12 ...(2)

By equation (1) and (2)

y+12+y=4

2y= 4-12=-8

y = -4

Now put the value of y in equation (2)

x= y+12=-4+12=8

So the larger number is 8 and the smaller number is -4.

A function can have an asymptote if it approaches a horizontal or vertical line but never touches it. There are several types of functions that can have asymptotes, including rational functions, exponential functions, and logarithmic functions.

For example, a rational function is a function that can be written in the form of a ratio of two polynomials. These functions can have horizontal asymptotes if the degree of the denominator is greater than the degree of the numerator, and they can have vertical asymptotes if the denominator has a factor that is not present in the numerator.

Exponential functions can have horizontal asymptotes if the base of the exponent is less than 1, and they can have vertical asymptotes if the base of the exponent is greater than 1.

Logarithmic functions can have horizontal asymptotes if the base of the logarithm is less than 1, and they can have vertical asymptotes if the base of the logarithm is greater than 1.

It's also possible for a function to have both horizontal and vertical asymptotes, depending on its form.

The values of p and q are 11 and 3 respectively.

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers. Simply said, the mean is the average of the values in the given collection. It indicates that values in a certain data collection are distributed equally.

Given that,

∑f = 40

=> 26+p+q = 40

=>p+q=40-26

=> p+q = 14 .......................(i)

∵ x bar = ∑xf/∑f

=>14.7 = 408+9p+27p / 40 (since, x bar = 14.7)

=>588 = 408+9p+27p

=>588 - 408= 9(p+3p)

=>180= 9(p+3p)

=>p+3q=20......................(ii)

Solving equations (i) and (ii)

=>p+3q -(p+q)=20-14

=>p+3q-p-q=6

To find the median of a set of numbers, you first need to put the numbers in order from smallest to largest. Then, if there is an odd number of values, the median is the middle value. If there is an even number of values, the median is the average of the two middle values.

In this case, the set of numbers is already in order: [2, 4, 5, 6, 7, 8, 11]. There are 7 values, so the median is the middle value, which is 6.

So, the median of the set {7, 6, 4, 8, 2, 5, 11} is 6.

Answer:

1 balloon is = £2 and 1 cake is = £4

Step-by-step explanation:

this is true because 2 balloons = £4

and 3 cakes = £12 so 4 + 12 = 16 and also

4 balloons = £8

and 4 cakes = £16 so 8 + 16 = £24

this is one of the possible answers

Answer:

A cake is £3.50

A Balloon is £2.75

Step-by-step explanation:

Let b be balloons and c be cake

2 balloons and 3 cakes = £16 = 2b + 3c = 16

4 balloons and 4 cakes = £24 = 4b + 4c = 25

First times -2 to the first equation

-4b - 6c = -32

4b + 4c = 25

Now let's find c first by adding the two equations together.

-2c = -7

c = £3.50

Now put 3.50 back in the c

4b + 4(3.50) = 25

4b + 14 = 25

4b = 11

b = £2.75

The formula of current I is I=V/R.

In the field of physics, current can be described as the rate that shows the intensity of electrons that are flowing from one place to another.

The current is the measure of the potential difference from which the current moves forward when resistance is also a factor that stops it. Electric current is directly proportional to the potential difference applied and is inversely proportional to the resistance in the object in which the electric current is flowing.

Based on this fact, the formula for current, which is represented by the letter I is   I=V/R, here I is the current, V is the potential difference and R is the resistance.

The zeros of the function y = x^2 - 4x - 5 = 0 are 5 and -1.

The given function is y = x^2 - 4x - 5 = 0

We know that the general form of a quadratic equation is:

ax^2 + bx + c =0

On comparing the given equation y = x^2 - 4x - 5 = 0 with the general form of a quadratic equation ax^2 + bx + c =0 we get that:

a= 1, b = -4, c = -5

On multiplying a and c, we get -5 and the factors of it are 1 and 5.

Hence we can break the equation into:

x^2 - 5x + x - 5 = 0

We can factor it into:

x (x -5) + 1 (x - 5) = 0

(x + 1) (x - 5) = 0

Dialyzer re-use efficiency is largely determined by the fiber bundle volume (FBV).

This estimation is performed after the dialyzer has been pressure cleaned and may underrate the level of coagulated strands a patient really experiences while on dialysis.

The package's dimensions:

length = 32 in

width = level = 16 in

Volume of bundle = 8192 in³

The square-shaped package is depicted in the attached image.

Expect that the length is y in and that width = level = x in (since the base is a square)

This implies that the circumference is 4*x = 4x in

We are given that the greatest amount of length and circumference is 96.

This indicates:

This can be rewritten as: y + 4x = 96

The volume of the package can be calculated as follows: y = 96 - 4x..............> I

Volume is equal to the following: length * width * height * y * x * x = x2y in3 Substitute equation I for the following volume equation:

Volume = x2 (96-4x) = 96x2 - 4x3 in3 to achieve maximum volume:

dV/dx = 0 indicates that:

2(96) x - 4(3) x2 = 0 192x - 12x2 = 0 x (192-12x) = 0

either x = 0.......> This is rejected because the side cannot be zero or 192 - 12x = 0...............> 192 = 12x...............> x = 16 in.......> accepted

In Part (b), y = 96 - 4x = 96 - 4(16) = 96 - 64 = 32: obtaining a volume:

When the degree of an equation is even and the leading coefficient is positive, the graph of the equation will be a parabola. This parabola will open upwards, meaning that it will start at the y-axis and increase in value as x increases. The vertex of the parabola will be the lowest point on the graph, and this vertex will always be located to the right of the y-axis. Additionally, the parabola will be symmetrical about the line of symmetry, which is the vertical line that passes through the vertex. To further illustrate, consider the equation y = 4x^2 + 5x + 1. In this equation, the degree is even (2) and the leading coefficient is positive (4). Therefore, the graph of this equation will be a parabola that opens upwards and has its vertex to the right of the y-axis.
