Step-by-step explanation:

distance in x direction:  ║-4║ + 2 = 6

distance in y direction:  5 + ║-2║ = 7

Use pythagorean theorem to find hypotenuse of triangle with legs of 6 and 7:

[tex]d^{2} = 6^{2} + 7^{2} = 85\\d = \sqrt{85} = 9.2195 = 9.22[/tex]

A) The slope is 3/2

B) The line in point-slope form: y = (3/2)*(x - 2) + 10

C) The line in slope-intercept form: y = (3/2)*x  + 7

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

a = (y2 - y1)/(x2 - x1)

Here the line goes through (2, 10) and (-2, 4), then the slope is:

a = (10 - 4)/(2 + 2) = 6/4 = 3/2

b) The line in point-slope form for a point (h, k) is:

y = a*(x - h) + k

So here we get:

y = (3/2)*(x - 2) + 10

c) Expanding the above equation we will get:

y = (3/2)*x - (3/2)*2 + 10

y = (3/2)*x  + 7

a) The slope is infinity.

b) We can't write the linear equation in the slope-intercept form because the slope is infinity, in this case, the line is written as x = 2.

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

slope = (y2 - y1)/(x2 - x1)

Here we have two points (2, 1) and (2, 0), then the slope is:

slope = (1 - 0)/(2 - 2) = 1/0 → ∞

So the slope is infinity, as the case for all vertical lines.

b) Why we can't write the linear equation in the traditional form?

This happens because the slope is infinity, the vertical linear equations are written as:

x = a

In this case, we can see that the line is at x = 2, so that is our linear equation.

The slope of the vertical line in the given graph is undefined.

The equation of the line is x = 2.

The slope of a vertical line is usually undefined because the horizontal change (change in x) is equal to 0. Thus, we cannot divide a number by 0. Therefore, the slope of a vertical line is undefined.

The line given is a vertical line that intersects the x-axis at 2. Its slope is undefined. Since its slope is undefined, it is impossible to write the equation of the vertical line in the traditional version of the point-slope form. Hence, it is written as x = b, where b is the point where the x-axis is intersected by the line.

Slope of the line is undefined. The equation is x = 2.

The distance between the point (5,12) and the line y = 5x + 12 is 4.90 units

If a point P with the coordinates (x₁, y₁), and we need to know its distance from the line represented by ax + by + c = 0

Then the distance of a point from the line is given by the formula:

d = (ax₁ + by₁ + c) / √(a² + b²)

Given: the point (5,12) and the line y = 5x + 12. The line can be written as

5x-y+12 = 0. Thus:

x₁ = 5, y₁ = 12, a = 5, b = -1, c = 12. Substitute these into the formula:

d = (ax₁ + by₁ + c) / √(a² + b²)

d = (5×5 + (-1×12) + 12) / √(5² + (-1)²)

d = 25/√26 = 4.90 units

Therefore, the distance between the point and the line is 4.90 units. Option D is the answer

Step-by-step explanation:

Let x = total number of pages in the book.

She read half the book in Monday. She read x/2.

She read 90 pages on Tuesday. By now she read a total of x/2 + 90.

She has 1/8 left to go. That means she read 7/8 of the book.

7/8 x = x/2 + 90

Multiply both sides by 8.

8 × 7/8 x = 8 × x/2 + 8 × 90

7x = 4x + 720

3x = 720

The equation for resistor 2, R₂ is (d) R₂ = R₁Rt/(R₁ - Rt)

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

Rt = R₁R₂/(R₁ + R₂)

The question implies that we make R₂ the subject of the formula

So, we have

Rt = R₁R₂/(R₁ + R₂)

Cross multiply the equations

(R₁ + R₂)Rt = R₁R₂

Open the brackets

So, the equation becomes

R₁Rt + R₂Rt = R₁R₂

Collect the like terms

R₁R₂ - R₂Rt = R₁Rt

Factor out R₂

R₂(R₁ - Rt) = R₁Rt

Using partial quotient, the place value while subtracting is determined by the dividend.

divisor    dividend    quotient  multiplication  subtraction  new dividend

5             1175            200         200 * 5 = 1000        1175 - 1000 = 175

5             175             30            30 * 5 = 150             175 - 150    =  25    

5             25              5              5 * 5 = 25                 25 - 25      = 0

The quotient is then added as

= 200 + 30 + 5

= 235

Assuming the quotient was written 2. While subtracting, the dividend for the first value (1175) is in thousands. placing the the 2 in thousands makes it more than the dividend hence the 2 should be in hundreds

1175 - 2000 incorrect

The Mean measure should be used to summarize the data in all three problems.

What is the mean?

In mathematics, particularly statistics, there are several types of means. Each mean is used to summarize a specific group of data, often in order to better understand the overall value of a data set.

Generally,

For ratio and interval type of data, we use mean as the central tendency

For the ordinal type of data, we use the median as the central tendency

and For the nominal type of data mode is prefered.

Interval data:- In this type of data point lies in some interval on a scale.

Like temperature in degrees Fahrenheit, it has some range of value on the measurement scale of temperature.

Ratio Data:- It is similar to interval type of data but absolute zero is treated as the point of origin.No negative value

Example:- temperature in kelvin (0 is the origin)

Ordinal data:- It is of categorical type of data that is in the natural order and the distance between the two data is not known.

Example:- How you describe your last purchasing experiences,

1) Very Pleasant 2) Somewhat Pleasant 3) Neutral 4) Somewhat Unpleasant 5) Very Unpleasant.

Nominal data:- In this data is leveled or named without any quantitative value.

Example:- Colour of hair, gender, country, etc.

a)

In part (a) the data is ratio type.

Hence, the Mean is the best central tendency of measurement.

b)

In (b) part also ratio type of data.

Hence, the Mean is the best central tendency of measurement.

C)

In this part, data is of the Interval data.

Hence, the Mean is the best central tendency of measurement.

Therefore, the Mean measure should be used to summarize the data in all three problems.
