The greatest possible quotient of any two distinct members of the set; { 2 / 5, 1 / 2, 5, 10 } as required is; 25.

It follows from the task content that the set from which the two numbers whose quotient is to be maximised is; { 2 / 5, 1 / 2, 5, 10 }.

On this note, since the quotient which is to be maximised is hypothetically; x / y;

To maximize the result of the quotient; it follows that the numerator, x must be as great as possible and the denominator, y must be as less as possible.

On this note, since the maximum number in the set is 10 and the minimum is 2 / 5; we have that;

10 / (2 / 5)

= ( 10 × 5 ) / 2

= 25.

Ultimately, the greatest possible quotient as required is; 25.

Answer:

x = 5/3

Step-by-step explanation:

6x + 11 = 21

6x = 10

x = 10/6

x = 5/3

Let's check

6(5/3) + 11 = 21

30/3 + 11 = 21

10 + 11 = 21

21 = 21

So, x = 5/3 is correct!

The number of coordinates needed to specify the position and orientation of a rigid body in an n-dimensional space is n.

A rigid body is an object that maintains its shape and size while in motion. In order to specify the position and orientation of a rigid body in an n-dimensional space, we need to know its coordinates in each of the n dimensions. The coordinates describe the location of the body in the space and the orientation of the body relative to the space's coordinate system. Thus, n coordinates are required to fully specify the position and orientation of a rigid body in an n-dimensional space.

However, it is important to note that if the rigid body is placed in a space that's non-Euclidean, other parameters could be necessary to fully describe the rigid body position and orientation.

To find the y-coordinate of the solution, we can substitute in this value for y and round it to the nearest tenth: y = -2.2

system of coordinates, Arrangement of reference lines or curves for locating points in space The Cartesian (named for René Descartes) system is the most popular one in two dimensions.

To solve for y in the equation 5x + 2y = 21, we can start by isolating y on one side of the equation. To do this, we can subtract 5x from both sides of the equation:

5x + 2y = 21

5x - 5x + 2y = 21 - 5x

2y = 21 - 5x

To solve for y, we can then divide both sides of the equation by 2:

2y = 21 - 5x

y = (21 - 5x) / 2

To solve for y in the equation -21 + 6y = -34, we can start by isolating y on one side of the equation. To do this, we can add 21 to both sides of the equation:

-21 + 6y = -34

-21 + 21 + 6y = -34 + 21

6y = -13

To solve for y, we can then divide both sides of the equation by 6:

6y = -13

y = -13/6

y = -2.1666666666666665

To find the y-coordinate of the solution, we can substitute in this value for y and round it to the nearest tenth:

The probability for all five answers is greater than 0.

The normal distribution is a type of continuous probability distribution, and probability can never equal 0 for a continuous distribution. The probability of a particular value (in this case, 8) is the area under the normal curve at that point. Since the area under a continuous distribution is always greater than 0, the probability of a specific value (A) is not 0.

The probability of a range of values (D) is calculated by subtracting the area under the normal curve to the left of the lower value, from the area under the normal curve to the right of the higher value. This calculation would produce a value greater than 0.

The probability of values greater than a given number (B) is calculated by subtracting the area under the normal curve to the left of the given number, from the area under the normal curve to the right of the given number. This calculation would produce a value greater than 0.

The probability of values less than a given number (C) is calculated by subtracting the area under the normal curve to the right of the given number, from the area under the normal curve to the left of the given number. This calculation would produce a value greater than 0.

Finally, the probability of values less than one number or greater than another number (E) is calculated by subtracting the area under the normal curve to the left of the lower number, from the area under the normal curve to the right of the higher number.

So, Mathilda should mix 600 grams of OMT with 300 grams of WMT to sell the resulting mixture at Php 1.80 per gram.

The unitary approach involves calculating the value of a single unit, from which we may calculate the values of the necessary number of units.

The unitary method's formula is to identify the value of a single unit, then multiply that value by the number of units to obtain the required value.

A unit is a quantity with a fixed magnitude that is used to gauge the sizes of other quantities that behave similarly.

The terms millimeter (mm), centimeter (cm), meter (m), and kilometer (km) are used to describe length (km). The weight is measured in kilograms (kg) and grams (g). Milliliter (ml) and liter are used to measure volume (L).

Let x be the amount of OMT powder in grams. We know that the total amount of powder in the mixture is x + 300 grams since Mathilda is mixing x grams of OMT with 300 grams of WMT.

(x * Php 2 + 300 * Php 1) / (x + 300) = Php 1.80

Solving for x, we can get the amount of OMT powder in grams:

x = (300 * Php 1.80 - 300 * Php 1) / (Php 2 - Php 1.80) = 300 * (Php 1.80 - Php 1) / (Php 2 - Php 1.80) = 600

It looks like there may be a typo in the function you provided. It appears that you meant to write "f(x) = 80(0.5)^x", which would represent the distance after a pendulum begins swinging, where x is the number of swings.

This function indicates that the distance traveled by the pendulum decreases by half with each swing. For example, after the first swing, the distance traveled would be 80(0.5)^1 = 40 units. After the second swing, the distance traveled would be 80(0.5)^2 = 20 units. And so on.

The exponent x in the function represents the number of swings, so the distance traveled by the pendulum can be calculated by plugging in the desired value of x into the function. For example, to calculate the distance traveled after 10 swings, we can plug in x = 10:

f(10) = 80(0.5)^10 = 0.390625 units

This indicates that the pendulum has traveled a distance of approximately 0.39 units after 10 swings.

To solve this pair of equations, we can use the substitution method.

First, we solve the first equation for y:

2y = 4 - 3x

y = (4 - 3x) / 2

Next, we substitute this expression for y in the second equation:

2x + (4 - 3x) / 2 = 5

2x + 2 - 3x = 10

-x = 8

x = -8

Finally, we substitute this value for x in the expression for y to find the value of y:

y = (4 - 3(-8)) / 2

y = (4 + 24) / 2

y = 28 / 2

Work Shown:

x = number of years

y = population

y = 4000*1.02^x

4500 = 4000*1.02^x

4500/4000 = 1.02^x

1.125 = 1.02^x

log(1.125) = log(1.02^x)

log(1.125) = x*log(1.02)

x = log(1.125)/log(1.02)

x = 5.94784893412128

Rounding to the nearest year, it takes about 6 years for the population to reach 4500 people.

Check:

Plug in x = 5

y = 4000*1.02^x

y = 4000*1.02^5

y = 4416.3232128

y = 4416

J (-9, -8) -> J' (8, -9)

First, you take negative 8 (y) of J and make it positive 8 for the x of J'. Then, take -9 (y) of J and switch it to x of J'.

No, triangle ABC is not a right triangle. The equation of a line BC "y=x-11" is a line with slope of 1, which means it has an angle of 45 degrees with respect to the x-axis. The segment AB has a slope of 0, which means it is parallel to the x-axis. A right triangle's legs must be perpendicular, therefore a line with a slope of 1 and a line with a slope of 0 cannot be the legs of a right triangle.

A right triangle is a triangle in which one of the angles is 90 degrees. In order for a triangle to be a right triangle, the two sides (or legs) that form the 90-degree angle must be perpendicular to each other. Perpendicular lines have slopes that are negative reciprocals of each other.

In this case, the equation of the line segment AB is "y = -6", which means it is parallel to the x-axis. The slope of a line parallel to the x-axis is 0. On the other hand, the equation of the line BC is "y = x - 11", which means it has a slope of 1. A slope of 1 means that the line is at a 45 degree angle with respect to the x-axis.

Since the slopes of the two lines are not negative reciprocals of each other (0 and 1), the legs of the triangle cannot be perpendicular. Therefore, triangle ABC cannot be a right triangle.
