The slope of the line that contains the points: (-7, 8) and (12, 8) is 0

From the question, the points are given as

(-7, 8) and (12, 8)

Rewrite the above points properly

So, we have the following ordered pairs

(x, y) =  (-7, 8) and (12, 8)

The slope of the line is then calculated using the following slope equation

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) =  (-7, 8) and (12, 8)

Substitute the known values in the above equation

So, we have the following equation

Slope = (8 - 8)/(12 + 7)

Evaluate

Slope = 0

Hence, the slope of the line is 0

The simplified expression, when using the Quotient rule is b. 1 / 8⁴.

The Quotient Rule allows us to be able to carry out operations on quotients. The rule is such that when dividing quotients with the same base, you should subtract the quotients. For multiplication, you add the quotients.

8 ⁵ / 8 ⁹ will therefore be:

= 8 ⁵ ⁻ ⁹

= 8 ⁻⁴

8 ⁻⁴  is the equivalent of  1 / 8⁴ because when a number is taken to a negative power, then that number becomes a denominator to 1.

The slopes of the lines are 2/3, 5, 5/6 and 1 respectively

The slope of a line is a measure of its steepness or incline. It is defined as the ratio of the vertical change (called the "rise") to the horizontal change (called the "run") between two points on the line.

The slope of a line can be expressed using the following formula:

Slope = (y₂ - y₁) / (x₂ - x₁)

where (x₁, y₁) and (x₂, y₂) are two points on the line.

1.  P₁(0,2) and P₂(3,4):

Slope = (4-2)/(3-0) = 2/3

2.  P₁(1,2) and P₂(3, 7):

Slope = (7-2)/(3-2) = 5/1 = 5

3. P₁(-1,1) and P₂(5,6):

Slope = (6-1) / (5-(-1)) = 5/6

4. P₁(-1,-2) and P₂(10,11)

Slope = (11-(-1)) / (10-(-2)) = 12/12 = 1

The first derivative of the implicit functions are listed below:

In this problem we have an implicit function of the form f(x, y) = 0, whose first derivative shall be found by implicit differentiation. Now we proceed to present the procedure. First, write the entire expression:

2 · x² + 8 · x · y + 6 · y² + 13 · y - 2 = 0

Second, use the derivative rules:

4 · x + 8 · y + 8 · x · y' + 12 · y · y' + 13 · y' = 0

4 · x + 8 · y + (8 · x + 12 · y + 13) · y' = 0

y' = - 4 · (x + 2 · y) / (8 · x + 12 · y + 13)

The same procedure is used in the next two implicit functions:

3 · x³ = 2 · y² - 9 · y

9 · x² = 4 · y · y' - 9 · y'

9 · x² = (4 · y - 9) · y'

y' = 9 · x² / (4 · y - 9)

3 · y² = 5 · x - (2 / 5) · x + 2

Given √24−x when x = 6 in simple radical form is 3*√2.

Simply put, simplifying a radical eliminates the need to find any further square roots, cube roots, fourth roots, etc.

Additionally, it entails eliminating any radicals from a fraction's denominator.

The square root of 2 or root 2 is represented using the square root symbol √ and written as √2 whose value is 1.414.

So, we have:

√24−x when x = 6
Thus we must now calculate the square root of 18.

The square root, if you're allowed to use a calculator, is 4.242.

If not, however, let's come as close as we can:

The required straight equation will be y = -0.5x + 27.5 passes through the points  (-5, 0) and (5, 2).

What are equations in a straight line?

A straight line's equation is given by y=mx+c, where c is the height at which the line intersects the y-axis (often referred to as the y-intercept) and m is the gradient.

According to the given graph,

We can see two points are (-5, 0) and (5, 2)

The linear equation will be: y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

Here

x₁ = -5, y₁ = 0

x₂ = 5, y₂ = 2

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₂]

Substitute values in the equation, we get

⇒ y - 0 = (2 - 0)/(8-4)(x-(-5))

⇒ y - 30 = (2)/(-4)(x + 5)

⇒ y - 30 = -1/2(x + 5)

⇒ y = (-1/2)x - 5/2 + 30

⇒ y = -0.5x + 27.5

Thus, the required equation will be y = -0.5x + 27.5 passes through the points  (-5, 0) and (5, 2).

In the given question, a random sample of 12 employees was taken, and the number of days each was absent for sickness was recorded (for a 1-year period).

Using these data to create a 95% confidence interval for the population mean days absent for sickness

2   5   3   7   10   0   6   8   5   11   3   1

a) We have to find the sample mean and the standard deviation (round to two decimal places).

The sample mean;

X = 2+5+3+7+10+0+6+8+5+11+3+1/12

X = 61/12

X = 5.0833

Now the standard deviation

SD = √[{x(1)-X)^2+(x(2)-X)^2…………….(x(12)-X)^2}/N]

After solving using that formula;

SD = 3.476

b) 95% confidence in interval for the population mean days absent for sickness.

Lower Bound = X - t(α/2)*s/√n

Upper Bound = X + t(α /2)*s/√n

where

α /2 = (1 - confidence level)/2 = 0.025

X = sample mean = 5.083333333

t(α/2) = critical t for the confidence interval = 2.20098516

s = sample standard deviation = 3.476108936

n = sample size = 12

df = n - 1 = 11

Thus,

Lower bound = 2.874719086

Upper bound = 7.291947581

What is Exterior angle theorem?

The exterior angle theorem describes the connection between the two remote angles in a triangle and the external angle created by an extended side outside the triangle.

Given: Measure of angle YWX = (3x + 17) °

Measure of angle WXY = (3x + 2) °

Measure of angle XYZ = (10x − 5) °

Therefore, m∠XYZ = m∠YWX + m∠WXY (exterior angle theorem)

⇒ (10x − 5) ° = (3x + 17) ° + (3x + 2) °

Solve for x,

⇒ 10x - 5 = 3x + 17 + 3x + 2

⇒ 10x - 6x = 17 + 7

⇒ 4x = 24

⇒ x = 6

x=0.2km

3600second= 1 hour  

24 seconds =b   [b=(24s/3600s)x1 hour ]

b=0.0067(in 2 decimal place)

velocity in km/h will be

0.2km/0,0067secs

=29.85(in 2 decimal place)

Answer:

speed = 30 km/h

Step-by-step explanation:

We are told that a 200 metres race is run by an athlete in 24 seconds. The question then asks us to calculate the athlete's speed in km/h.

To do this, let's first convert the given data into the required units:

• Converting from metres to kilometres:
To convert from 200 metres to kilometres, we have to divide it by 1000:

200 m = 200 m ÷ 1000 m/km

           = 0.2 km

• Converting from seconds to hours:
To convert 24 seconds to hours, we have to divide it by 3600:

24 s = 24 s ÷ 3600 s/h

        = [tex]\frac{24}{3600}[/tex] h

Now that we have the data in the appropriate units, we can use the following formula to calculate speed:

[tex]\boxed{\mathrm{speed = \frac{distance}{time}}}[/tex]

⇒ speed = [tex]\mathrm{\frac{0.2 \ km}{24/3600 \ h}}[/tex]

⇒ speed = 30 km/h

Therefore, the speed of the athlete is 30 km/h.

Answer:

x = 40°

y = 35°

Step-by-step explanation:

Let us take two triangles ∆ABC and ∆ADE

We know that, in a triangle the sum of all angles is equal to 180°

So,

For the traingle ABC

Now,

m∠A + m∠B + m∠C = 180°

80° + 60° + x° = 180°

140° + x° = 180°

x° + 140° - 140° = 180° - 140°

x = 40°

For the triangle ADE

Now,

m∠A + m∠D + m∠E = 180°

80° + 65° + y° = 180°

145° + y° = 180°

y° + 145° - 145° = 180° - 145°

y = 35°

Thus, The value of x and y is 40° and 35° respectively
