Answer: The distance between a and c is 8 units

Step-by-step explanation:

You can count the number of units they are apart, but if there isn’t a grid, then do this:

If x or y values in the ordered pairs are different, subtract them from each other and find the absolute value of the difference. (It’s my own rule, so there is a better method. My explanation apples only to ordered pairs that share a x or y value, like A and C)

2-(-6) = 8, and the absolute value of 8 is 8

Or

(-6)-2 = (-8), and the absolute value of -8 is 8 (You’ll get the same answer)

Barbara can buy a combination of earrings and necklaces with a total cost of no more than $144. We need to determine how many of each item she can buy within her budget.

Let's assume Barbara buys x earrings and y necklaces. The cost of earrings will be 12x, and the cost of necklaces will be 24y. According to the problem, the total cost must be no more than $144, so we have the inequality:

12x + 24y ≤ 144

To find the possible combinations, we can test different values of x and y that satisfy this inequality. Since we want to maximize the number of items Barbara can buy, we can start by setting x and y to their maximum possible values.

The maximum number of earrings Barbara can buy is 144/12 = 12 pairs. The maximum number of necklaces she can buy is 144/24 = 6 necklaces.

By trying different combinations within these limits, we find that Barbara can buy 0 earrings and 6 necklaces, spending a total of $144, or she can buy 6 earrings and 0 necklaces, also spending a total of $144.

Therefore, Barbara can either buy 6 necklaces or 6 earrings within her budget of $144.

Therefore, the result of (u*v)v is a vector with components (80, -16).

In mathematics, a vector is a mathematical object that has both magnitude and direction. Vectors are used to represent physical quantities such as force, velocity, and acceleration, as well as abstract mathematical quantities such as points, lines, and planes. A vector is usually represented geometrically as an arrow in a coordinate system, where the length of the arrow represents the magnitude of the vector, and the direction of the arrow represents the direction of the vector. Vectors can be added, subtracted, and multiplied by scalars, and these operations follow specific rules that make them a powerful tool for solving problems in mathematics, physics, engineering, and other fields. Vectors can have any number of dimensions, but in two-dimensional space, a vector can be represented as an ordered pair of numbers (x, y), where x and y represent the horizontal and vertical components of the vector, respectively. In three-dimensional space, a vector can be represented as an ordered triplet of numbers (x, y, z), and so on for higher dimensions.

Here,

To find (u*v)v, we first need to find the dot product of u and v, which is defined as:

u · v = (4, 4) · (-5, 1)

= (4 × -5) + (4 × 1)

= -20 + 4

= -16

Next, we need to multiply the dot product of u and v by v:

(u*v)v = (-16)(-5, 1)

= (80, -16)

The coordinates E (-5, 3), F (-3, 5), G (5, -1), and H (one, negative) allow us to visualize and analyze the trapezoid's properties and relationships between its sides and angles.

The trapezoid EFGH is a polygon with four sides and one set of equal sides. The names of its vertices are as follows: The numbers are E (-5, 3), F (-3, 5), G (-5, -1), and H (one, negative).

On a Cartesian plane, the vertices' individual situations are addressed by their directions. In this case, E is located at (-5, 3)—that is, it is 5 units to the left and 3 units above the origin. In like manner, F is at (- 3, 5), exhibiting it is 3 units aside and 5 units over the start.

The trapezoid's parallel sides are EF and GH. The trapezoid's base is EF, and its top side is GH. By dividing the difference in y-coordinates squared by the square root of the difference in x-coordinates squared, the distance formula can be used to calculate the length of EF. In this case, EF is the square root of (22 + 22) = 8.

According to its coordinates, G is 5 units to the right and 1 unit below the origin. H (one, negative) indicates that it is one unit to the right of the origin and below the x-axis.

In conclusion, specific vertex coordinates define the trapezoid EFGH's shape and location on a Cartesian plane. The trapezoid's properties and connections between its sides and points can be imagined and investigated using the directions E (- 5, 3), F (- 3, 5), G (5, - 1), and H (one, negative).

The angle subtended by an arc of length 'r' of a circle whose radius exists 'r' is comprehended as 1 radian.

The relations between sexagesimal measure (degree), centesimal measure(grade), and circular measure (radian) are

π radians = 180 Degrees

90 Degrees = 100 grades

⇒ 180 Degrees = 200 grades

Therefore, 180 Degrees = 200 grades = π radians

To transform the value of the angle in degree, to its equivalent radians, we must multiply the given value by π/180.

For instance, the value of 180 degrees is π in radians.

In a complete rotation, the length of the intercepted arc exists equivalent to the circumference of the circle or 2πr.

Dividing the equation 180 degrees = π radians

The relations between sexagesimal measure (degree), centesimal measure(grade), and circular measure (radian) are

π radians = 180 Degrees

90 Degrees = 100 grades

⇒ 180 Degrees = 200 grades

The equation does not give any specific values for "x" and "y", we can conclude that there are infinitely many pairs of positive numbers that satisfy both conditions. The product of these numbers will be the maximum.

Let's assume the two positive numbers as "x" and "y". We want to find the values of "x" and "y" that satisfy two conditions:

The sum of six times the first number and twice the second number is equal to 150: 6x + 2y = 150.

The product of the two numbers is maximum.

To find the values of "x" and "y" that maximize their product, we can use a mathematical principle known as the AM-GM inequality. According to this inequality, the arithmetic mean of two positive numbers is always greater than or equal to their geometric mean. In other words:

(x + y) / 2 ≥ √(xy)

Let's proceed with solving the problem:

Rewrite the equation from condition 1: 6x + 2y = 150.

Divide both sides of the equation by 2 to simplify it: 3x + y = 75.

Rearrange the equation to express y in terms of x: y = 75 - 3x.

Substitute this value of y into the equation from condition 1: 6x + 2(75 - 3x) = 150.

Simplify the equation: 6x + 150 - 6x = 150.

The equation simplifies to: 150 = 150.

This equation is an identity, meaning it is true for any value of "x" and "y".

Since the equation does not give any specific values for "x" and "y", we can conclude that there are infinitely many pairs of positive numbers that satisfy both conditions. The product of these numbers will be the maximum.
