The limit of the function [[3 · cos (2 - 2x) - 3 · x] / (2 · x - 2)] when x tends to 1 is - 3 / 2.

In this problem we must determine the limit of a function, that is, the value to which the function goes when x tends to 1. This can be done by means of limit properties for polynomial and trigonometric limits.

First, write the limit:

[tex]\lim_{x \to 1}[/tex] [[3 · cos (2 - 2x) - 3 · x] / (2 · x - 2)]

Second, use limit properties and algebra properties:

[tex]\lim_{x \to 1}[/tex] [[3 · cos (2 - 2x) - 3 + 3 - 3 · x] / (2 · x - 2)]

[tex]\lim_{x \to 1}[/tex] [[3 · cos (2 - 2x) - 3] / (2 · x - 2)] + [tex]\lim_{x \to 1}[/tex] [(3 - 3 · x) / (2 · x - 2)]

(3 / 2) · [tex]\lim_{x \to 1}[/tex] [[1 - cos (1 - x)] / (1 - x)] + (3 / 2) · [tex]\lim_{x \to 1}[/tex] [(1 - x) / (x - 1)]

Third, use polynomial and trigonometric limits:

(3 / 2) · 0 + (3 / 2) · (- 1)

Fourth, simplify the result:

What does rate in math mean?

In mathematics, the term 'rate' usually refers to a ratio or a comparison between two different values. It is defined as the amount of one quantity with respect to another, and is most commonly expressed as a fraction, with one value being the numerator and the other being the denominator. For example, "the rate of increase" is a comparison between the amount of increase in an item over time, such as the rate of inflation over a period of time. Additionally, the term 'rate' can also be used to describe a rate of change, such as the rate of growth of a population. In this case, the rate of change describes how quickly the population is changing over time.

Given that:

For rate we have to differentiate all the function first

Answer:

Step-by-step explanation:

the adjacent angles are congruent

angle 1 = 51°

the sum of the angles is 360°

51 · 2 + 2 · angle (2) = 360

102 + 2angle(2) = 360

2angle (2) = 360 - 102

2 angle (2) = 258

angle (2) = 258/2

angle (2) = 129°

angle (3) = 129°

A 31.2 foot ladder is required to access an electrical box that is 28 feet up.

Which ratios in trigonometry are there?

Sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant are the six trigonometric ratios (sec). A branch of mathematics called trigonometry in geometry deals with the sides and angles of a right-angled triangle.

A right-angled triangle is formed by the ladder, the distance from the wall to the ladder's base, and the distance from the ground to the electrical box.

The link between the sides and angles of a right-angled triangle is demonstrated through trigonometric ratios.

If x stands for the ladder's length, then:

28 feet/x for sin(64).

28 feet/sin x = (64)

x = 31.2 ft

Therefore, a 31.2-foot ladder is required to reach an electrical box that is 28 feet up.

Answer:

11.8 m

Step-by-step explanation:

this makes up a right triangle so we can use the Pythagorean theorem

a^2+b^2=c^2

a- height/leg a

b- length/ leg b

c- hypotheneus

since we are tying to find b we can isolate b^2 on one side of the equation

a^2+b^2=c^2

-a^2.       -a^2

b^2=c^2-a^2

And now we can plug in values

b^2=36^2-34^2

b^2=1296-1156

b^2=140

Square root both sides

twice of 1/8 = 2/8 = 1/4

Answer:

25%

Step-by-step explanation:

"twice" means two times.

"twice the value of 1/8" is

2 × 1/8

(to multiply a whole number times a fraction, multiply the big number × the top number)

2 × 1/ 8 is 2/8

2/8 is 1/4.

1/4 = .25 = 25%

Since the answer is a percent, change 1/4 to a decimal, .25, change the decimal to a percent.

Or you could change 1/4 to 25/100. Percent means "per hundred" 25/100 is 25%.

  C.  x² -8x +16 = 20

Step-by-step explanation:

You want the next step in completing the square after you get x² -8x = 4.

The constant in a perfect square monic trinomial is the square of half the coefficient of the linear term.

The coefficient of x is -8. Half that is -4, and its square is (-4)² = 16. This will be the value added to the equation in the second step.

  x² -8x +16 = 4 +16

  x² -8x +16 = 20

Additional comment

A monic polynomial has a leading coefficient of 1. We generally work with monic quadratics when completing the square. We do this by factoring the leading coefficient out of the variable terms.

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Slope can be determined by using two points (x1, y1) and (x2, y2) and putting them in rise-over-run format (rise-over-run is equal to slope)

in this case we can use (3, 2) as (x1, y1) and (0, 0) as (x2, y2)

Rise-over-run format is: [tex]\frac{y2 - y1}{x2 - x1}[/tex]

so substitute our number in and you get: [tex]\frac{2-0}{3-0}[/tex]

solve to get: [tex]\frac{2}{3}[/tex]

this is your slope

It should be noted that 23.4 is 8.1 percent of 288.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

23.4 is what percent of 288 will be calculated thus:

= 23.4 / 288 × 100

= 8.1%

Answer:

2x+y=-4

Step-by-step explanation:

y-2=-2(x+3) is in point-slope form.

Ax+By=C is standard form.

We have to bring x and y to the same side of the equation.

First, let's distribute.

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

y-2=-2x-6

Next, we will add 2 to both sides to get rid of the -2 on the left side of the equation.

y=-2x-6+2

Then, we will add 2x to both sides to get rid of the -2x on the right side of the equation.

2x+y=-6+2

Now x and y are on the same side of the equation. We just need to simplify the right side.

2x+y=-4

This is the answer in standard form.

Answer:

2x + y = -4

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{5.5 cm}\underline{Standard form of a linear equation}\\\\$Ax+By=C$\\\\where:\\ \phantom{ww}$\bullet$ $A, B$ and $C$ are constants. \\ \phantom{ww}$\bullet$ $A$ must be positive.\\\end{minipage}}[/tex]

Given equation:

[tex]y-2=-2(x+3)[/tex]

To write the given equation in standard form, collect the terms with variables on the one side of the equation (ensuring the term in x is positive), and collect the constants on the other side of the equation.

Distribute the right side of the equation:

[tex]\implies y-2=-2 \cdot x+(-2) \cdot 3[/tex]

[tex]\implies y-2=-2x-6[/tex]

Add 2x to both sides of the equation:

[tex]\implies y-2+2x=-2x-6+2x[/tex]

[tex]\implies y-2+2x=-6[/tex]

Add 2 to both sides of the equation:

[tex]\implies y-2+2x+2=-6+2[/tex]

[tex]\implies y+2x=-4[/tex]

Rearrange the left side to standard form:

[tex]\implies 2x+y=-4[/tex]

Answer:

Step-by-step explanation:

The standard form of a linear equation is y=mx+b, where m is the slope and b is the y-intercept.  Let's rewirite the given equation to match this format:

 y = 6 - 6x

 y = -6x + 6

The slope is -6 and the y-intercept is 6.  The slope tells us the angle the line is taking.  A negative slope such as this means that the line is angled down as it goes from left to right.  The size of the number tells us just how steep the line is.  

All parallel lines have the same slope.  Any line with the format of y = -6 + b will be parallel.  See the attached graph for proof.  The graph shows several parallel lines to y=-6+b, including the three top lines, all with the same slope, but with three different values for b:  +6, 0, and +10.

Perpendicular lines have a slope that is the negative inverse  of the reference line, in this case y = -6x + 6.  A perpendicular line will have a slope of -(1/-6) or 1/6 [the negative inverse of -6].  Perpendicular lines will have the form y = (1/6)x + b.  See the attached graph.  The three bottom equations are all perpendicular to y=-6x+6.  All have the same slope (1/6), but differnt y-intercepts (b = 0, 6, and 10).  The y-intercept numbers for both the parallel and perpendicular lines were randomly chosen, simply to illustrate the possibilities.

In summary,

"Slope of a parallel line" is -6, and

"Slope of  perpendicular line" is (1/6)

The function that has a graph that is parallel to the graph of 2x-y=6 is y = 2x - 8

From the question, we have the following parameters that can be used in our computation:

2x - y = 6

Subtract 2x from both sides of the equation

So, we have the following representation

-y = -2x + 6

Multiply both sides of the equation by -1

y = 2x - 6

Also, from the question;

We have the following points

The point is given as

Point = (3, -2) i.e.  (x, y) = (3, -2)

The equation of a line can be represented as

y = mx + c

Where

Slope = m

By comparing the equations, we have the following

m = 2

This means that the slope is 2

The slopes of parallel lines have the same values

This means that the slope of the other line is 2

The equation of the line is then calculated as

y = m(x - x₁) +y₁

Where

m = 2

(x₁, y₁) = (3, -2)

So, we have

y = 2(x - 3) - 2

Open the brackets

y = 2x - 6 - 2

Evaluate the like terms

y = 2x - 8

Hence, the line has an equation of y = 2x - 8

Answer:

Step-by-step explanation:

Given a set of parallel lines with a transversal and angles marked, you want to find the values for x and y consistent with the markings.

Alternate interior angles are congruent, so the marked acute angles have the same measure:

  3x +2y = 52

Corresponding angles are congruent, so the marked obtuse angles have the same measure:

  18x +2y = 142

Subtracting the first equation from the second gives ...

  (18x +2y) -(3x +2y) = (142) -(52)

  15x = 90

  x = 6

The value of y can be found from either equation. We choose to use the first:

  3(6) +2y = 52

  9 +y = 26 . . . . . . . . divide by 2

  y = 17 . . . . . . . . . subtract 9
