Therefore, the distance from the coal tray is approximately 301.96 inches when the heat intensity is 0.685 and the width of the coal tray is 25 inches.

We can write the following using the formula in the question:

[tex]P = 100/(1 + d^2)[/tex]

where d represents the proportion of the food's distance from the coals to the tray's width.

Substituting d = z/25 results in:

[tex]P = 100/(1 + (z/25)^2)[/tex]

With y = 0.685, we can replace P with P = 0.685 and find z:

[tex]0.685 = 100/(1 + (z/25)^2)[/tex]

By dividing the two sides by [tex](1 + (z/25)^2)[/tex], we get at:

[tex]0.685 + 0.685(z/25)^2 = 100[/tex]

If we simplify, we get:

[tex](z/25)^2 = (100/0.685) - 1(z/25)^2 = 145.9854[/tex]

When we square the two sides, we obtain:

[tex]z/25 = 12.0783z = 25*12.0783z = -25*12.0783[/tex]

Given that z cannot be negative, we decide:

Z=25 * 12.0783 * 301.9575 inches

Answer:

stretch by 2, right 4, down 1

Step-by-step explanation:

In a function in the form:

f(x) = a(x - h)² + k

the number in front, a, shows vertical stretch (if its bigger than 1. Its a shrink or smash if its a fraction less than 1)

Horizontal shifts are shown in close next to the x, inside the parenthesis shown here with an h. Horizontals shifts are maybe the opposite of what you might think they should be. + anumber is a left shift and - anumber is a right shift.

Vertical shifts are shown by a number tacked onto the end of the equation, k These shifts are more intuitive. + anumber shifts up and - anumber shifts down.

For your equation:

f(x) = 2(x-4)²-1

The 2 is a vertical stretch. The -4 by the x is a right shift 4. The -1 tacked into the end is a shift down 1

To find a point that represents a solution for the equation x + 3y = 8, we need to find a point (x,y) that satisfies this equation. One way to do this is to choose a value for x, and then solve for y. For example, if we let x = 2, we have:

2 + 3y = 8

Subtracting 2 from both sides, we get:

3y = 6

Dividing both sides by 3, we get:

y = 2

So the point (2,2) is a solution for the equation x + 3y = 8. To check, we can substitute x = 2 and y = 2 into the equation:

2 + 3(2) = 8

8 = 8

This is true, so (2,2) is a solution for the equation.

Alternatively, we could choose a value for y and solve for x. For example, if we let y = 0, we have:

x + 3(0) = 8

x = 8

So the point (8,0) is also a solution for the equation x + 3y = 8.

Therefore , the solution of the given problem of unitary method comes out to be  1,440 students who favor ice cream

The task may be completed using this generally accepted ease, existing variables, and any important components from the original Diocesan customizable query. If so, you might get another opportunity to work with the object. Otherwise, algorithmic evidence will no longer be affected by any significant factors.  

Here,

The table shows that 81 of the 225 students favor ice cream.

Out of the 4,000 students, we can use the following proportion to estimate how many favor ice cream:

=> 81/225 = x/4000

If we cross-multiply, we obtain:

=> 225x = 81 * 4000

If we simplify, we get:

=> 225x = 324,000

By multiplying both parts by 225, we obtain:

=> x = 1440

The college will have about 1,440 students who favor ice cream, so that is the best guess as to how many scoops of ice cream the college will require.

Step-by-step explanation:

The sample space for rolling a fair 12-sided die is S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.

Sample space refers to the set of all possible outcomes or events that can occur in an experiment or random process. It is denoted by the symbol "S" and contains all the possible values, results, or states that can be observed or measured. In probability theory, the sample space is used to define the range of possible outcomes that can be observed or measured in a given experiment or event.

Probability is a measure of the likelihood or chance of an event occurring. It quantifies the likelihood of an event happening based on the ratio of the number of favorable outcomes to the total number of possible outcomes. It is expressed as a value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

According to the given information:

When you roll a 12-sided dice, number of dots on the uppermost face is called as outcome. Now, whenever a dice is rolled we can get either 1, 2,3,4,5,6,7,8,9,10,11 or 12 dots on the uppermost face that is now outcome.

So experiment here is "Rolling a 12-faced dice" and list of possible outcomes is "{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}".

Sample space by its definition is list of all the possible outcomes of an experiment.

Answer:

[tex]\textsf{A.} \quad \dfrac{1}{4}[/tex]

Step-by-step explanation:

Given geometric sequence:

[tex]8,\;2,\;\dfrac{1}{2},\;\dfrac{1}{8},\;\dfrac{1}{32}[/tex]

The common ratio for a geometric sequence can be found by dividing a term by the previous term.

[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{2}{8}=\dfrac{2 \div 2}{8 \div 2} =\dfrac{1}{4}[/tex]

Therefore, the common ratio for the given geometric sequence is 1/4.

To find the middle term of the expansion of (2x/y^3)^12, we need to first determine the number of terms in the expansion.

Using the formula for the binomial theorem, we know that the number of terms in the expansion of (2x/y^3)^12 is 13.

Now, to find the middle term, we need to find the term that is in the middle of the expansion. Since there are 13 terms in the expansion, the middle term is the 7th term.

The general term of the expansion is given by:

T(r+1) = (12 C r) (2x)^r (y^-3)^(12-r)

So, the 7th term is:

T(8) = (12 C 7) (2x)^7 (y^-3)^(5)

Simplifying this expression, we get:

T(8) = (792) (128x^7 / y^15)

Therefore, the middle term of the expansion is 792(128x^7/y^15)

What is division?

Division is a basic arithmetic operation in mathematics that involves dividing one number by another. It is denoted by the symbol "/", or by the horizontal fraction bar. The number being divided is called the dividend, while the number it is being divided by is called the divisor. The result of the division is called the quotient. For example, if we divide 10 by 2, the dividend is 10, the divisor is 2, and the quotient is 5. The formula for division is:

dividend / divisor = quotient

In some cases, division may result in a remainder. For example, if we divide 10 by 3, the quotient is 3 with a remainder of 1. This can be expressed as 10 / 3 = 3 remainder 1, or as a mixed number, 3 1/3. In other cases, the division may result in a decimal or a fraction.

Here,

1) To divide (x² + 6x + 9) by (x + 3), we can use polynomial long division as follows:

x + 3 | x² + 6x + 9

- x² - 3x

-------

3x + 9

3x + 9

-----

0

Therefore, the quotient is x + 3 , dividend is x² + 6x + 9, divisor is (x+3) and the remainder is 0.

So, (x² + 6x + 9) = (x+3)×(x-3) + 0

2) To divide (x² - 9x + 18) by (x - 6), we can use polynomial long division as follows:

x - 6 | x² - 9x + 18

- x² + 6x

-------

-15x + 18

-15x + 90

--------

-72

Therefore, the quotient is x - 3, dividend is (x² - 9x + 18), divisor is x-6 and the remainder is -72.

So, (x² - 9x + 18) = (x-6)×(x-3) + (-72)

3) To divide (x² + 4x - 7) by (x + 5), we can use polynomial long division as follows:

x + 5 | x² + 4x - 7

- x² - 5x

-------

-x - 7

-x - 5

------

-2

Therefore, the quotient is (-x + -1), dividend is x² + 4x - 7, divisor is x+5 and the remainder is -2.

So, (x² + 4x - 7) = (-x-1)×(x+5) + (-2)

Percentage is a way of expressing a number or proportion as a fraction of 100. It is represented by the symbol "%".

The growth rate of E.Coli is given as 1.9% per minute, which can be expressed as 0.019 per minute as a decimal.

Let N(t) be the number of E.Coli present at time t. Then, we can write the differential equation governing the population growth as:

dN/dt = rN,

where r is the growth rate (0.019 per minute in this case).

The general solution to this differential equation is:

N(t) = [tex]N0e^{(rt)}[/tex]),

where N0 is the initial population size.

We are given that the current number of E.Coli present is 172, so N0 = 172. We want to find N(8.5), so we plug in t = 8.5 and solve:

1) the midpoint of the line segment is (2, 2.5). 2) the slope of the line is -3.25.  3)the length of the line segment is approximately 13.60.    4) the equation of the line is y = -3.25x + 9.

what is slope ?

In mathematics, the slope of a line is a measure of its steepness, defined as the ratio of the vertical change (rise) between two points on the line to the horizontal change (run) between the same two points. It is often denoted by the letter "m".

In the given question,

To find the midpoint of the line segment that connects the points (4,-4) and (0,9), we use the midpoint formula:

Midpoint = ((x₁ + x₂)/2, (y1 + y₂)/2)

Midpoint = ((4 + 0)/2, (-4 + 9)/2)

Midpoint = (2, 2.5)

So the midpoint of the line segment is (2, 2.5).

To find the slope of the line that passes through the two given points, we use the slope formula:

Slope = (y₂ - Ly₁)/(x₂ - x₁)

Slope = (9 - (-4))/(0 - 4)

Slope = 13/-4

Slope = -3.25

So the slope of the line is -3.25.

To find the length of the line segment that connects the two given points, we use the distance formula:

Length = √((x₂ - x₁)² + (y₂ - y1)²)

Length = √((0 - 4)² + (9 - (-4))²)

Length = √(16 + 169)

Length = √(185)

Length ≈ 13.60

So the length of the line segment is approximately 13.60.

Now, we can use the point-slope formula to find the equation of the line that passes through the point (4,-4) with slope -3.25:

y - y1 = m(x - x₁)

y - (-4) = -3.25(x - 4)

y + 4 = -3.25x + 13

y = -3.25x + 9

According to the popular legend, Archimedes discovered a principle of buoyancy while taking a bath.

what was his discovery ?

He realized that the volume of water displaced by his body was equal to the volume of his body. This insight led him to formulate the principle of buoyancy, which states that an object placed in a fluid experiences an upward force equal to the weight of the fluid it displaces.

Archimedes was reportedly so excited by this discovery that he ran through the streets of Syracuse shouting "Eureka!" (meaning "I have found it" in Greek). This principle has numerous practical applications, including in shipbuilding and the design of submarines and other underwater vehicles.

In geometric terms, the principle of buoyancy can be explained using the concept of displacement. When an object is submerged in a fluid, it displaces a certain volume of fluid, which is equal to the volume of the object. This volume of fluid has weight, and the fluid exerts an upward force on the object that is equal to the weight of the displaced fluid. This is what causes objects to float in water or other fluids, as long as their weight is less than the weight of the fluid they displace.

As for what Archimedes did next with his new discoveries, it's difficult to say for certain, as there are many stories and legends about his life. However, we do know that he was a prolific inventor and mathematician, and he likely continued to explore the implications of his principle of buoyancy and other discoveries. He may have also used this principle in his work as an engineer and designer, creating new machines and devices that were more efficient and effective thanks to his insights into fluid mechanics.

Step-by-step explanation:

The coordinates of the points that make up the function are equal to (x, y).

If we reflect the function over the y-axis, the sign of the y-value stays the same due to still being on the same side of the x-axis. The x-value sign will be the opposite of its current value due to being reflected over the y-axis.

This leads us to the algebraic expression:
