The distance from the center point to a corner flag is approximately 6.4 cm on the plan

The length and width of the rectangular field, on a scale of 1 cm to 10 m, can be represented as 104 m / 10 = 10.4 cm and 76 m / 10 = 7.6 cm, respectively. The half of the length is 5.2 cm and the half of the width is 3.8 cm.

To find the distance from the center point to a corner flag, we need to use the Pythagorean theorem. The distance is the square root of the sum of the squares of half the length and half the width:

√(5.2^2 + 3.8^2) = √(27.04 + 14.44) = √41.48

So the distance from the center point to a corner flag is approximately 6.4 cm on the plan.

The solution to the given system of inequalities is x belongs to (-1/3, 7).

The system of two inequalities represents two lines in a 2D plane and the solution is the common area between the two lines that satisfies both inequalities. Here's one way to solve this system:

Solve each inequality for x to get the equation of a line:

m<2: 4x - 26 < 2 -> 4x < 28 -> x < 7

m<3: 3x + 4 < 3 -> 3x < -1 -> x < -1/3

Plot both lines on a coordinate plane and shade the region where both inequalities are satisfied.

The solution is the set of all points that satisfy both inequalities and lies in the shaded region, which is x < 7 and x < -1/3. The solution is therefore x < min(7, -1/3) = -1/3 < x < 7.

So, the solution to the system of inequalities is x belongs to (-1/3, 7).

For the given figure, the value of different angles, x = 122° and w = 90°.

An angle is a shape in planar geometry made up of two rays or lines that have a common termination. The Latin word "angulus," which meaning "corner," is where the English term "angle" originates. The shared termini of two rays are the vertex and the two rays, which are referred to as the sides of an angle, respectively. When two rays meet at a point, they create an angle. The "angle," which is the term used to describe the "opening" between these two rays, is represented by the symbol. Angles are typically expressed as 60°, 90°, etc. and are measured in degrees.

For the given figure,

The value of angle w is 90°.

The value of angle x = 180 - 58 = 122°

The value of 2w - 25 will be = 2 × 90 - 25 = 155°

If Donna is running around a track. It takes her 3 1/2 minutes to run 1/4 of a lap. If she keeps running at the same speed. The time it take her to run 5 laps is:  70 minutes .

1. It takes Donna 3 1/2 minutes to run 1/4 of a lap. So,

it takes her 3 1/2 * 4 = 14 minutes to run 1 full lap.

Thus, it will take her 14 * 5 = 70 minutes to run 5 laps.

2. To find the rate needed, we need to know the time and distance. Since Donna runs 1/4 of a lap in 3 1/2 minutes.

The rate can be expressed as 1/4 lap / 3 1/2 minutes.

3. To find the unit rate, we need to convert the time to a common unit, such as seconds.

So,

3 1/2 minutes = 3.5 * 60

= 210 seconds.

The unit rate will then be 1/4 lap / 210 seconds.

The total amount to be paid back would be $35,731.73.

The amount is 100 words. Plagiarism is not allowed, so the answer must be original and unique.The amount is unspecified and cannot be determined without further information.

This can be calculated using the formula for compound interest:

A = P(1 + r/n)^nt,

where A is the total amount to be paid back, P is the principal amount (31,000), r is the annual interest rate (3%), n is the number of times the interest is compounded per year (annually in this case), and t is the number of years (11).

Plugging this into the formula, we get:

A = 31000 (1 + 0.03/1)^11

A = 31000 (1.03^11)

A = 31000 (1.357364)

A = $35,731.73

The change in the density rho of a substance when the temperature changes by δt is dρ = -β × δt × ρ.

The change in density, dρ, of a substance when the temperature changes by delta_t (δt) can be calculated using the coefficient of thermal expansion, beta (β):

dρ = -β × δt × ρ

Where rho is the original density of the substance. If beta * delta_t is much less than 1 (beta * delta_t << 1), then the change in density can be considered to be small, and the original density can be used in the calculation.

Therefore, the change in density rho is -β × δt × ρ.

F[g(x-1)] has a value of 2x2-4x+9. Applying the multiplication operation to functions and replacing the functions led to the discovery of the answer.

The functions can be added, subtracted, multiplied, or divided in the same manner that we add, subtract, multiply, and divide the terms in a function.

Consider f(x) and g, two functions (x). These are the notations:

To add, use the formula (f+g)(x) = f(x) + g(x)

for subtraction (f-g)(x) = f(x) - g(x)

To multiply, use the formula (fg)(x) = f(x)* g(x)

The division formula is (f/g)(x) = (f(x))/(g(x)).

A function that considers one function to be a component of another function is created when we replace one function for another.

So now, f(g) = 2g-3.

When provided, g = x^2+5

So, g(x-1) = (x-1)^2+5

The mean of the uncertainty distribution is 3.7

The probability distribution of a random event describes the likelihood of each possible outcome of that event.

In the case of the modified die at Pharaoh's Palace, the management has changed the standard probability distribution so that the probability of each side is proportional to the number of spots on the side.

The possible outcomes are 1, 2, 3, 4, 5, and 6, and their probabilities can be calculated by summing up the probabilities of each side and ensuring that they add up to 1.

The mean of the uncertainty distribution is calculated by taking the sum of each possible outcome multiplied by its probability and dividing by the number of possible outcomes.

As per the quadratic equation, the value of k is 48 ± 8√26.

The term called quadratic equation is known as the polynomial equation whose highest degree is two

Here we know that the value of the quadratic equation is written as,

=> (k - 4)x² - 3kx - 4(k -2) = 0.

Here we have identified that the given equation is in the form of ax² + bx + c = 0.

Then the value of a = k - 4, b = -3k and c = 4(k-2)

Now, we have to use the quadratic formula to identify the value of k, then it can be written as.

=> (-3k)² - (4 x (k - 4) x 4(k-2))

=> 9k² - ((4k - 16) x (4k - 8))

=> 9k² - (16k² - 32k - 64k + 128)

=> 9k² - 16k² +96k -128 = 0

y=-1/4x-2 is the  equation of the line that is perpendicular to y = 4x + 6 and passes through the point (8, −4).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The slope of perpendicular line will be -1/m

In the equation  y = 4x + 6  the slope m is 4

The slope of perpendicular line will be -1/4

Now let us find the y intercept

-4=-1/4(8)+b

-4=-2+b

-2=b

y=-1/4x-2 is the equation of perpendicular line.

Hence, y=-1/4x-2 is the  equation of the line that is perpendicular to y = 4x + 6 and passes through the point (8, −4).
