Find the length of the circumferences of the circles whose diameters is 49​

To convert an area from inches to centimeters, conversion factor should be 15.24 square centimeters.

To convert an area from inches to centimeters, we use the conversion factor of 2.54 cm per inch.

This means that for every inch, there are 2.54 centimeters. In order to find the area in centimeters, we first need to find the area in inches, and then multiply it by 2.54.

To find the area, we use the formula
=> area = length x width.

Let's say the length of a rectangle is 2 inches and the width is 3 inches. The area of this rectangle would be 6 square inches

=> (2 x 3 = 6).

To convert this area to square centimeters, we multiply the area in inches by 2.54.

So,

=> 6 square inches x 2.54 = 15.24 square centimeters.

The tilde approximation of the growth function f(n) = n + 5n^4 + nlg(n) is ~5n^4.

The tilde notation is used to describe the asymptotic behavior of a function, which means how the function grows relative to other functions as the input gets very large.

To determine the tilde approximation of the function f(n) = n + 5n^4 + nlg(n), we need to identify the term that grows the fastest as n becomes very large.

Analyze the first term: n. As n gets larger, the term n becomes relatively smaller compared to the other terms in the function.

Analyze the second term: 5n^4. This term grows much faster than the first term as n becomes larger.

Analyze the third term: nlg(n). The logarithmic term grows slower than the polynomial term, meaning that it becomes relatively smaller as n becomes larger.

Based on the analysis above, we can conclude that the dominant term in the function is 5n^4.

Therefore, the tilde approximation of the function f(n) = n + 5n^4 + nlg(n) is ~5n^4, meaning that the function grows approximately as n^4 when n becomes very large.

You can use the equation:

k = 125 / 5

Where k is the number of emergency kits that Brody packs and 5 is the number of water bottles he puts in each kit.

This equation is determined based on the information given in the problem: "Brody puts 5 water bottles into each kit they pack, and in all, he packs 125 water bottles." To find the number of kits, we need to divide the total number of water bottles (125) by the number of water bottles in each kit (5). This gives us the number of kits, k, that Brody packs.

This equation is specific to this problem and may not be applicable to every problem. It depends on the specific information given in each problem. In general, to determine the equation for a problem, you need to understand the relationships between the variables involved and express them mathematically.

Total number of ways to get from bottom left cell to the top right cell in a  13 × 13 grid using move two cells up or three cells to the right is equal to    2 ways.

Size of the grid is 13 × 13.

Number of rows = 13

Number of columns = 13

Condition for the movement is two cells up or three cells to the right direction.

Here neither 2 nor 3 is a multiple of 13.

It is not possible to divide 13 by any one.

First way of movement is:

Four movement of three cells to the right and then six movement of two cells up.

Second way:

And three cells right →two cells up→ three cells right →two cells up→ three cells right →two cells up→ three cells right →two cells up three times.

The probability that the first ball is red and the second one is blue is 0.3.

This is calculated by first finding the probability of drawing a red ball, which is 3/5, and then the probability of drawing a blue ball after a red ball has been removed, which is exactly evaluated as 1/4. To find the combined the probability, we multiply the two probabilities: 0.3 = (3/5) * (1/4). This means that if we perform this experiment many times, on average, we would expect to draw a red ball first followed by a blue ball in 30% of the trials.

The correct method of labelling the population for SRS is 001 - 690.

What is a simple random sample(SRS)?

In statistics, a simple random sample is a subset of people chosen at random from a larger group, all of whom were chosen with the same probability. It is a method of choosing a sample at random.

For the given question,

Total number of students = 690

Number of students to be selected for SRS = 50

One method of creating a straightforward random sample is to number the students from 1 to 690 before using a random number generator to select 50 numbers. A random sample is the most effective at eliminating potential bias because every member of the population has an equal chance of being chosen.

Any two participants must have an equal chance of being selected for the sample, and any group, that isn't larger than the sample size, must be able to have all of its members selected.

Therefore the correct method of labelling the population for SRS is 001 - 690.

Differentiation from First Principles is a formal method for determining a tangent's gradient.

What is meant by differentiation?

Finding a function's derivative is the process of differentiation. It is also the process of determining how quickly a function changes in relation to its variables.

According to the Sum rule, a sum of functions' derivatives equals the sum of those functions' derivatives. The derivative of two different functions is the difference of their derivatives, according to the Difference rule.

Differentiation from First Principles is a formal method for determining a tangent's gradient. The straight line connecting any two locations on the curve that are fairly near to one another will have a gradient that is similar to that of the tangent at those places.

s(t) = ∫vdt = ∫sin(πt)dt = (-cos(πt))/π + c

substituting the values t = 3, we get

s(-3) = (-cos(-3π))/π + c = 0

simplifying the above equation, we get

(-cos(3π))/π + c = 0

1/π + c = c

c = -1/π

Therefore, the correct answer is s(t) = (-cos(πt))/π - 1/π = (-cos(πt) - 1)/π.

A system of linear equations for the graph below is y = -3x + 3  Y=1/3x-7

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter 'm'.

Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation. The m is the slope of the line. And b is the b in the point that is the y-intercept (0, b). For example,

The point is a solution to the system of linear equations is (3/4, 1/4).

A system of linear equations consists of two or more equations, each of which has two or more variables, all of which are taken into account concurrently. Any ordered pair that satisfies each equation separately is the solution to a system of two-variable linear equations.

Let the equation be

x + y = 1 ------(1)

3x - y = 3 ------(2)

Add equation (1) and (2), we get

x + y + 3x - y = 1 + 2

simplifying the equation, we get

⇒ 4x = 3

⇒ x = 3/4

Put x = 3/4 in equation (1), then

3/4 + y = 1

simplifying the equation

y = 1 - 3/4

y = 1/4

(x, y) = (3/4, 1/4)

A plane is traveling at a constant speed of K kilometers per hour. The coordinate represented on the graph is option A: (1,K)

What is speed?

The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

The plane is traveling at a constant speed of K kilometers per hour.

K is considered the speed of the plane.

The formula for speed is given as -

Speed = Distance / Time

K = Distance / Time

Distance = K × Time

The value of time is given 1 hour.

Distance = K × 1

Distance = K miles

Como se puede ver, el gasto del canal calculado con el método de integración gráfica coincide con el caudal transportado, por lo que el cálculo es correcto.

El caudal transportado es el volumen (m3) de agua que fluye a través de una sección transversal de un canal por unidad de tiempo, en este caso es de 18.4m3/s. La pendiente de fondo es la pendiente de la superficie de fondo de un canal, en este caso es de 0.022. El coeficiente de rugosidad es una medida de la rugosidad del canal, en este caso es de 0.024.

Para calcular el gasto del canal utilizando el método de integración gráfica, se usa la siguiente fórmula:

Q = A*(S^(1/2))*C*(L^(2/3))

Donde Q es el gasto en m3/s, A es el área de sección transversal del canal en m2, S es la pendiente de fondo en m/m, C es el coeficiente de rugosidad del canal y L es la longitud del canal en m.

En este caso, el área de sección transversal es de 18.4m2, la pendiente de fondo es de 0.022 m/m, el coeficiente de rugosidad es de 0.024 y la longitud del canal es de 400m.

Utilizando los datos anteriores, el gasto del canal es de:

Q = 18.4 * (0.022^(1/2)) * 0.024 * (400^(2/3))

Q = 18.4 * 0.05 * 0.024 * 8.93
