We want to write it in slope-intercept form:

y = mx + (b' = -12m - 2).

The slope of parallel lines is the same. The slopes of perpendicular lines are opposite reciprocals. To put it another way, if m=ab, then m=ba. To find the equation of a line, first determine the slope using the given information.

We can use the fact that parallel lines have the same slope to find the equation of a line that is parallel to a given line and passes through a given point.

Assume that the given line has the equation y = mx + b, where m represents the slope and b represents the y-intercept.

The slope of the line we are looking for is m because it is parallel to the given line. Because we don't know what the y-intercept of this line is, let's call it b'.

We now have two pieces of information regarding the new line:

It has the same slope as the given line (m).

It runs through the point (12,-2).

We can use this data to calculate the equation of the new line:

To begin, we can use the point-slope form of a line equation:

y - y1 = m(x - x1) (x - x1)

(x1, y1) denotes the point (12,-2) and m denotes the slope of the given line.

Substituting known values:

y - (-2) = m(x - 12) (x - 12)

Simplifying:

y + 2 = mx - 12m

We must now calculate the value of b' that makes this equation true for any point on the line. Because b' is the line's y-intercept, we can set x = 0 and solve for y:

y + 2 = m(0) - 12m

y = -12m - 2

As a result, the equation of the line parallel to the given line and passing through the point (12,-2) is:

y = mx - 12m - 2

Alternatively, we can write it in slope-intercept form:

y = mx + (b' = -12m - 2).

Where m is the distance from A to P and n is the distance from P to B.

Length is a measure of distance or size. It is the measurement of the longest dimension of an object, such as a line, segment, or plane. It is commonly used to measure the physical size of objects, as well as the space between them. Length can be measured in many different units, such as meters, feet, or inches. Length is also used to measure the amount of time it takes for something to occur, such as the length of a movie or a song.
Therefore, if the coordinates of A are (x1, y1) and the coordinates of B are (x2, y2), the x- and y- coordinates of point P would be:

x= [2/3(x2 -x1) +x1
y = [2/3](y2 - y1) +y1

This equation can be used to calculate the coordinates of any point P on a directed line segment from A to B such that P is a fraction of the length of the line segment from A to B. By setting the fraction equal to 2/3, we can calculate the coordinates of point P that is 2/3 the length of the line segment from A to B. This can be useful in a variety of applications, such as computer graphics, game design, and engineering. For example, this equation could be used to calculate the coordinates of a point on a line segment that is an exact distance from the two endpoints, or to calculate the coordinates of a point that is a certain percentage of the distance between the two endpoints.

It is commonly used to measure the physical size of objects, as well as the space between them. Length can be measured in many different units, such as meters, feet, or inches.

Given the coordinates of the points A, B and P, we can calculate the x- and y- coordinates of point P such that it is 2/3 the length of the line segment from A to B.
To do this, we need to use the following formula: x = [m/m+n](x2 -x1) +x1, y = [m/m+n](y2 - y1) +y1, where m is 2/3, n is 1/3, x1 and y1 are the x- and y-coordinates of point A, and x2 and y2 are the x- and y-coordinates of point B.
In this case, m = 2/3, n = 1/3, x1 = 2, y1 = -1, x2 = 4, y2 = -3.
Therefore, plugging these values into the formula we get:
x = [2/3](4 -2) +2 = 4
y = [2/3](-3 - (-1)) + (-1) = -2

the pressure at a depth of 66 ft is 197,580 Pa, and the volume of the tank at this depth is 0.000505 L.

To find the pressure at a depth of 66 ft in a liquid, we can use the formula:

pressure = density x gravity x depth

Assuming the liquid in the tank is water, the density is 1000 kg/m³, and gravity is 9.81 m/s².

First, we need to convert 66 ft to meters:

66 ft x 0.3048 m/ft = 20.1168 m

Then, we can find the pressure at this depth:

pressure = 1000 kg/m³ x 9.81 m/s² x 20.1168 m = 197,580 Pa

To find the volume of the tank at this depth, we can use Boyle's Law, which states that the pressure and volume of a gas are inversely proportional at a constant temperature:

P₁V₁ = P₂V₂

where P₁ and V₁ are the initial pressure and volume (1 atm and 10 L, respectively), and P₂ and V₂ are the final pressure and volume.

We can rearrange this equation to solve for V₂:

V₂ = (P₁ x V₁) / P₂

Substituting the values, we get:

V₂ = (1 atm x 10 L) / (197,580 Pa / 1 atm) = 0.000505 L

To find:-

Answer:-

Here since the given triangle is a right angled triangle, we may use the trigonometric ratios . We can see that perpendicular and base are involved in this question whose measures are "x" and "√10" respectively with respect to 60° angle. So here we may use the ratio of tangent as , in any right angled triangle,

[tex]\implies\tan\theta =\dfrac{p}{b} \\[/tex]

and here p = x , and b = √10 . So on substituting the respective values, we have;

[tex]\implies \tan\theta = \dfrac{x}{\sqrt{10}} \\[/tex]

Also the angle here is 60° , so that;

[tex]\implies\tan60^o =\dfrac{x}{\sqrt10} \\[/tex]

The value tan60° is √3 , so we have;

[tex]\implies \sqrt3 =\dfrac{x}{\sqrt10}\\[/tex]

[tex]\implies x =\sqrt{10}\cdot \sqrt{3}\\[/tex]

[tex]\implies x =\sqrt{10\cdot 3} \\[/tex]

[tex]\implies x =\sqrt{30} \\[/tex]

The value of √30 is approximately 5.48 , so that;

Therefore the value of x is approximately 5.48 .

Answer:

The length of side x in simplest radical form is [tex]\sqrt{30}[/tex].

Step-by-step explanation:

From inspection of the given right triangle, we can see that the interior angles are 30°, 60° and 90°. Therefore, this triangle is a 30-60-90 triangle.

A 30-60-90 triangle is a special right triangle where the measures of its sides are in the ratio  1 : √3 : 2.  Therefore, the formula for the ratio of the sides is b: b√3 : 2b where:

We have been given the side opposite the 30° angle, so:

[tex]\implies b=\sqrt{10}[/tex]

The side labelled "x" is the side opposite the 60° angle, so:

[tex]\implies x=b\sqrt{3}[/tex]

Substitute the found value of b into the equation for x:

[tex]\implies x=\sqrt{10}\sqrt{3}[/tex]

[tex]\textsf{Apply the radical rule:} \quad \sqrt{a}\sqrt{b}=\sqrt{ab}[/tex]

[tex]\implies x=\sqrt{10 \cdot3}[/tex]

[tex]\implies x=\sqrt{30}[/tex]

Therefore, the length of side x in simplest radical form is [tex]\sqrt{30}[/tex].

[tex]\hrulefill[/tex]

We can also calculate the length of side x using the tangent trigonometric ratio:

[tex]\boxed{\tan \theta=\sf \dfrac{O}{A}}[/tex]

where:

From inspection of the given right triangle:

Substitute these values into the formula:

[tex]\implies \tan 30^{\circ}=\dfrac{\sqrt{10}}{x}[/tex]

[tex]\implies \dfrac{\sqrt{3}}{3}=\dfrac{\sqrt{10}}{x}[/tex]

[tex]\implies x\sqrt{3}=3\sqrt{10}[/tex]

[tex]\implies x=\dfrac{3\sqrt{10}}{\sqrt{3}}[/tex]

Rationalise the denominator by multiplying the numerator and denominator by √3:

[tex]\implies x=\dfrac{3\sqrt{10}}{\sqrt{3}}\cdot \dfrac{\sqrt{3}}{\sqrt{3}}[/tex]

[tex]\implies x=\dfrac{3\sqrt{10}\sqrt{3}}{3}[/tex]

[tex]\implies x=\sqrt{10}\sqrt{3}[/tex]

[tex]\implies x=\sqrt{10\cdot3}[/tex]

[tex]\implies x=\sqrt{30}[/tex]

Therefore, the length of side x in simplest radical form is [tex]\sqrt{30}[/tex].

By using the Pythagorean theorem we know that the given triangle is not a right triangle.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry.

According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Pythagorean triples consist of the three positive numbers a, b, and c, where a2+b2 = c2.

The symbols for these triples are (a,b,c). Here, a represents the right-angled triangle's hypotenuse, b its base, and c its perpendicular.

The smallest and most well-known triplets are (3,4,5).

So, we have the values already,

Now, calculate as follows:

3² + 4² = 6²

9 + 16 = 36

25 ≠ 36

Hence, the given triangle is not a right triangle.

The effective interest rate of the simple discount note is 6%.

The effective interest rate (EIR) of a simple discount note can be calculated using the following formula:

EIR = (Discount ÷ Face Value) x (360 ÷ t)

Where Discount is the difference between the face value and the discounted value, t is the time in days from the issuance of the note until its maturity, and 360 is the number of days in a year used for interest rate calculations.

In this case, the face value is $3,500, the bank discount rate is 11%, and the time to maturity is 24 months or 720 days.

Discounted value = Face value x (1 - Bank discount rate x t ÷ 360)

Discounted value = $3,500 x (1 - 0.11 x 720 ÷ 360)

Discounted value = $3,080

Therefore, the discount is $420 ($3,500 - $3,080).

Using the formula for EIR, we get:

EIR = ($420 ÷ $3,500) x (360 ÷ 720)

Answer:

Step-by-step explanation:

Let x be the measure of the first angle.

According to the problem, we know that:

The sum of the angles of the triangle is 180: x + y + z = 180

The sum of the second and third angles is five times the measure of the first angle: y + z = 5x

The third angle is 16 more than the second: z = y + 16

We can substitute the third equation into the second equation to get:

y + (y + 16) = 5x

Simplifying this equation, we get:

2y + 16 = 5x

We can rearrange this equation to get:

y = (5/2)x - 8

Now we can substitute this equation and the equation z = y + 16 into the first equation to get:

x + (5/2)x - 8 + (5/2)x + 8 = 180

Simplifying this equation, we get:

6x = 360

Dividing both sides by 6, we get:

x = 60

Now we can use this value of x to find y and z:

y = (5/2)x - 8 = (5/2)(60) - 8 = 58

z = y + 16 = 58 + 16 = 74

Therefore, the measures of the three angles are x = 60, y = 58, and z = 74.

Orlando and Nancy will be at an elevation of -110 when they are at the same elevation.

Step-by-step explanation:

We can set up an equation to find the time it takes for Orlando and Nancy to be at the same elevation

We will use the variable T to represent the time in minutes

Orlando's elevation : -60 + 8t

Nancy's elevation : -35 + 12t

We will solve for t to see at what time the elevations were equal

-60 + 8t = -35 + 12t

-60 + 35 = 12t - 8t

-25 = 4t

4t = -25

t = -6.25

This means that both will be at the same elevation 6.25 minutes before Orlando goes down

To find the elevation they will be at that time, we will plug -6.25 into either expression.

-60 + 8t = -60 + 8(-6.25) = -110

Orlando and Nancy will be at an elevation of -110 when they are at the same elevation.

Probability is used in many areas of life, such as gambling, finance, and science. It is also used to make decisions in everyday life, such as estimating the likelihood of rain or the chance of winning a bet.

The probability that John's drive to work will take between 36 and 40 minutes can be calculated using a normal distribution table. The mean of the distribution is µ = 38 minutes, and the standard deviation is σ = 5 minutes.

To calculate the probability, we need to convert the given range (36 minutes to 40 minutes) into standard normal scores. This is done by subtracting the mean (µ = 38 minutes) from the lower bound (36 minutes) and then dividing by the standard deviation (σ = 5 minutes). The result is a standard normal score of -0.4. The same calculation is carried out for the upper bound (40 minutes) and the result is a standard normal score of 0.4.

Using a normal distribution table, we can then determine the probability that John's drive to work will take between 36 and 40 minutes. This probability is equal to the area under the normal curve between the two standard normal scores of -0.4 and 0.4. The result is a probability of 0.3829.

Therefore, the probability that John's drive to work will take between 36 and 40 minutes is 0.3829.

Answer:

Step-by-step explanation:

To find the inventory turnover for Roselli's Machine Manufacturing Co, we need to use the formula:

Inventory turnover = Cost of goods sold / Average inventory

First, we need to find the cost of goods sold (COGS):

COGS = Sales - Gross profit

COGS = R120 000 - R50 000

COGS = R70 000

Next, we need to find the average inventory. We can use the quick ratio formula to find the current assets:

Quick ratio = (Current assets - Inventory) / Current liabilities

Rearranging the formula to solve for inventory, we get:

Inventory = Current assets - (Quick ratio x Current liabilities)

Plugging in the values we know, we get:

1.75 = (Current assets - Inventory) / R25 000

Current assets - Inventory = 1.75 x R25 000

Current assets - Inventory = R43 750

Inventory = Current assets - R43 750

Since the current ratio is 2.5, we know that:

Current assets / Current liabilities = 2.5

Solving for current assets, we get:

Current assets = 2.5 x R25 000

Current assets = R62 500

Substituting the values we found for inventory and COGS into the inventory turnover formula, we get:

Inventory turnover = COGS / Average inventory

Inventory turnover = R70 000 / [(R62 500 - R43 750) / 2]

Inventory turnover = R70 000 / (R18 750 / 2)

Inventory turnover = R70 000 / R9 375

Inventory turnover = 7.47

Therefore, the inventory turnover for Roselli's Machine Manufacturing Co is 7.47.
