The magnitude of the vector RS is found to be - 6√2.

The direction of the given vector RS is - Ф = 45° in the fourth quadrant clockwise

The algebraic representation of the distances among two points based on their coordinates (in coordinate system). The Pythagorean theorem is used to calculate distances between points in 2- and 3-dimensional Euclidean space using rectangular coordinates.

Now, in response to the question;

The coordinates of points R and S are (-3,3) and (-9,9), respectively.

The distance formula is described as follows for the points R and S:

RS² = (x₂ - x₁)² + (y₂ - y₁)²

RS = √[(x₂ - x₁)² + (y₂ - y₁)²]

R and S's coordinates are-

(x₁,y₁) = (-3,3)  and (x₂,y₂) = (-9,9).

Changing the values with in formula;

RS = √[(-9 + 3)² + (9 - 3)²]

RS = √[(-6)² + (6)²]

RS = √[36 + 36]

RS  = 6√2 (magnitude of the vector RS)

Now, estimate the direction of the vector RS.

A vector's direction is described by the angle it makes with such a horizontal line.

To determine the direction of a vector, use one of the following equations:

tan Ф = Δy/Δx

Where, x = horizontal change

and, y = vertical change

tan Ф = (y₂ - y₁)/(x₂ - x₁)

         = (-9 + 3)/(9 - 3)

tan Ф = -1

Ф = 45° angle of direction in the fourth quadrant clockwise.

As a result, the distance between coordinates R and s is observed to be 6√2, which is same as the magnitude of the given vector RS,

The difference quotient of f(t) is: (6 - 2h - 4t)

And when h tends to zero is (6 - 4t)

Here we have the function:

f(t) = (2t)(3 - t)

Expanding the function we get:

f(t) = 6t - 2t^2

Now we want to get the difference quotient, which is:

(f(t+h) - f(t))/h

Replacing our function there, we will get:

( 6*(t + h) - 2*(t + h)^2 - 6*t + 2*t^2)/h

Now we can simplify the numerator to get:

(6*t + 6*h - 2t^2 - 2h^2 - 4*t*h - 6t + 2t^2)/h

(6h - 2h^2 - 4th)/h

Now divide by h so we get:

(6 - 2h - 4t)

Now, remember that in the difference quotient we need to take the limit when h tends to zero, in that limit we will get:

(6 - 4t)

That is the difference quotient of the function f(t).

Answer:

x = 12

Step-by-step explanation:

NB. Supplementary angles / Angles of a straight line add up to 180°

180° - 124° (the given angle)

= 56°

This means that the other part of the angle must be equal to 56° ...in other words (4x + 8)° = 56°

(4x + 8)° = 56°

56° - 8°

= 48°

So 4x = 48°

-Divide both sides by 4 in order to get rid of the 4 infront of the x so that you're able to get x alone to solve.

4x ÷4 = 48° ÷4

x = 12

You can substitute 12 in the place of x to see if this is correct.

(4(12) +8)° = 56°

56° + 124° = 180°

....therefore x = 12

The given statement states that the sum of two vectors is  = (2 , 5).

Vector addition is the process of joining two or maybe more vectors to get a vector sum. The parallelogram law specifies the rules for adding and multiplying two or more vectors. When eigenvectors are aligned head to tail, this same vector total is calculated by drawing the same vector from the free tail to the free head.

Given two vectors are:

a =(13,-4 )

b = (-11,9)

The vector sum is,

M = [a1 + b1, a2 + b2]

  = (Mx, My).

Substitution of the value we  get:

The amount of springs the machine will make by 6 pm is; 96 strings

We are given that;

Amount of paper clips machine can make in an hour = 300 paper clips

Amount of strings the machine can make in an hour = 360 strings

Now, the machine starts working at 1pm and makes 450 paper clips.

Thus, time taken = 450/360 = 1.25 hours

This is at 2:15 pm

By 6pm, time taken would be 6:00 - 2:15 = 3:45 or 3.75 hours

Thus, number of springs made = 360/3.75 = 96 springs

C. When elements are represented in a Venn diagram (using circles), the placement of elements inside or outside the circles indicates their relationship to the sets being represented.

D. Yes, the elements written at the intersection of both circles form a subset of the two sets.

C. Place an element inside a circle to indicate that it is a member of the set indicated by the circle.

An element that is positioned at the intersection of two circles denotes an element that is a part of both sets that are symbolized by those circles.

Outside the circles: In a Venn diagram, an element that is positioned outside every circle does not belong to any of the sets being represented.

D. This is so because these components are a part of the intersection of the two sets and as such, they are a part of both sets. In set theory, all of the components that are shared by two sets are contained in their intersection. Due to their simultaneous membership in both sets, the elements at the intersection are a subset of both sets.

The slope of the line determined by the equation 2 x+y=5 is -2

A line's inclination or steepness can be determined using the slope formula. Finding the proportion of the change in the y-axis to the change in the x-axis allows it to be used to calculate the slope of any line.

The change in a line's "y" coordinate relative to its "x" coordinate is known as the line's slope.

The given equation =  2x + y = 5

It can be rewritten as: y = -2x + 5            (subtracted 2x from both the sides)

Work Shown:

M = number of miles

L = cost to rent a luxury car = 1.15M + 16.40

E = cost to rent an economy car = 0.80M+10.95

C = difference in price

C = L - E

C = (1.15M + 16.40) - (0.80M+10.95)

C = 1.15M + 16.40 - 0.80M-10.95

C = 0.35M + 5.45

Don't forget to distribute the negative to each term in the second parenthesis.

-------------------

Optional Section:

Let's say you drove M = 100 miles as an example.

The luxury car would cost L = 1.15M+16.40 = 1.15*100+16.40 = 131.40 dollars to rent.

The economy car would cost E = 0.80M+10.95 = 0.80*100+10.95 = 90.95 dollars to rent.

The difference in rental costs is L-E = 131.40-90.95 = 40.45 dollars.

Or you could say C = 0.35M+5.45 = 0.35*100+5.45 = 40.45

This means you pay $40.45 more if you go for a luxury car instead of an economy car.

The slope passing through the two given two points (1,3) and (4,9) is 2.

The slope of a line is a measurement of its steepness and direction.

A line's slope is defined like a change in y coordinate with respect to a change in x coordinate.

m = Δy/Δx

where,m is the slope

Where, tan θ = Δy/Δx

This tanθ is also known as the line's slope.

A line's slope can be determined by calculating using two points just on straight line. We can use the slope of line formula with the coordinates of a two points.

Consider the coordinates of those 2 points,

P1 = (x₁, y₁)

P2 = (x₂, y₂)

Then slope will become;

Slope = m = tan θ = (y₂ - y₁)/(x₂ - x₁)

Now, as per the given question;

(x₁, y₁) = (1,3) and,

(x₂, y₂) = (4,9)

Substitute the values in the formula of the slope;

m = (9 - 3)/(4 - 1)

m = 6/3

m = 2.

Therefore, the slope of the line passing through the stated points is found to be 2.
