b. Slope of GK = [tex]\frac{5}{3}[/tex] and Slope of adjacent to RS =  [tex]-\frac{3}{5}[/tex]

c. The parallelogram GHJK is Square.

Define the term parallelogram?

A quadrilateral with two sets of parallel sides is referred to as a parallelogram. As a result, a parallelogram's opposite sides are parallel and congruent in length, and its opposite angles are similarly congruent.

Given in figure GHJK, the vertices are G(-3, 6), H(2, 3), J(-1, -2), K(-6, 1)

a. Length of line = [tex]\sqrt{({x_{2}-x_{1})^{2} } + ({y_{2}-y_{1})^{2}}[/tex]

for points G(-3, 6) and K(-6, 1)

Length of GK = [tex]\sqrt{(-6+3)^{2} + (1-6)^{2} }[/tex] = [tex]\sqrt{34}[/tex]

Length of GK = [tex]\sqrt{34}[/tex]

Length of adjacent side (GH, KJ) to GK =  [tex]\sqrt{(2+3)^{2} + (3-6)^{2} }[/tex] = [tex]\sqrt{34}[/tex]

Length of adjacent to GK = [tex]\sqrt{34}[/tex]

b. [tex]Slope = \frac{(y_{2} -y_{1})}{(x_{2} -x_{1})}[/tex]

Slope of GK = [tex]\frac{(1 - 6)}{(-6 + 3)}[/tex] = [tex]\frac{5}{3}[/tex]

Slope of GK = [tex]\frac{5}{3}[/tex]

Slope of adjacent side to GK = [tex]\frac{3-6}{2+3}[/tex] = [tex]-\frac{3}{5}[/tex]

Slope of adjacent to RS =  [tex]-\frac{3}{5}[/tex]

c. All sides are equals to [tex]\sqrt{34}[/tex]

So, length of diagonal GJ = [tex]\sqrt{({-3+1))^{2} } + ({6+2})^{2}} = \sqrt{68}[/tex]

and length of diagonal HK = [tex]\sqrt{({2+6))^{2} } + ({3-1})^{2}} = \sqrt{68}[/tex]

All sides and diagonals are equal then parallelogram GHJK is Square.

Step-by-step explanation:

2 slices per person, and 8 slices in 1 cake means that 4 people can share 1 cake.

So, you would do the amount of people (60) divided by the number of people that can eat 1 cake (4) to end up with ordering 15 cakes

Brian is at the grand opening celebration of a supermarket. He spins a wheel with 10 equal-sized slices, as shown below. The wheel has 3 black slices, 3 grey slices, and 4 white slices. When the wheel is spun, the arrow stops on a slice at random. If the arrow stops on the border of two slices, the wheel is spun again. (a) If the arrow stops on a black slice, then Brian wins a gift card. Find the odds against Brian winning a gift card.​

Answers

The probability against Brian winning a gift card are approximately 3.118 to 1.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event happening is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Probability is used in various fields, such as statistics, finance, science, engineering, and gaming, to make predictions and decisions based on uncertain events.

In the given question,

The probability of the arrow stopping on a black slice is 3/10. Therefore, the probability of the arrow stopping on a non-black slice is 7/10.

If the arrow stops on the border of two slices, the wheel is spun again, so Brian has another chance to win. The probability of the arrow stopping on a non-black slice is 7/10, so the probability of the arrow stopping on a black slice on the second spin is 3/7.

To find the odds against Brian winning a gift card, we first find the probability of him not winning a gift card on either spin:

P(not winning) = P(non-black on first spin) + P(black on first spin and non-black on second spin)

P(not winning) = (7/10) + (3/10) × (4/7)

P(not winning) = 0.7571

The probability of not winning is 0.7571, so the odds against winning are:

Odds against winning = P(not winning) / P(winning)

Odds against winning = 0.7571 / 0.2429

Odds against winning = 3.118

Therefore, the odds against Brian winning a gift card are approximately 3.118 to 1.

Gasoline costs $0.83/liter and has a density of 900 g/liter. What is the cost of 48.5 kg of gasoline? Round to the nearest cent.​

Answers

By simplification, the cost of 48.5 kg of gasoline is approximately $0.04.

What is density?

Density is a physical property of matter that describes how much mass is present in a given volume of a substance. It is defined as the amount of mass per unit volume and is usually expressed in kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³). The formula for density is:

Density = Mass / Volume

First, we need to find the volume of 48.5 kg of gasoline using its density:

Volume = Mass / Density = 48.5 kg / 900 g/L = 0.05389 L

Next, we can find the cost of this volume of gasoline:

Cost = Volume x Price per liter = 0.05389 L x $0.83/L = $0.0448

Rounding this to the nearest cent, we get:

Cost = $0.04

Therefore, the cost of 48.5 kg of gasoline is approximately $0.04.

The frisbee would spend 2.62 seconds in air before touching ground.

What is an equation?

An equation is an expression that shows the relationship between numbers and variables using mathematical operators such as addition, subtraction, exponent, multiplication and division.

Let h represent the height of the frisbee after t seconds.

h = -16t² + 40t + 5

The time the Frisbee is in air is at h = 0, hence:

-16t² + 40t + 5 = 0

t = 2.62 seconds

The frisbee would spend 2.62 seconds in air

Find out more on equation at: https://brainly.com/question/2972832

#SPJ1

a) Note that given the above function the height of the Frisbee each second it is in the air are:

t=1; h=29 feett=2; h = 21 feett =3; h = -19

b) The frisbee lasts  t [tex]\approx[/tex] 2.6 (s) in the air.

What is the justification for the above response?

Recall that the function given is -16t² + 40t + 5
t=0; and h = 5

a)
Where t is 1
h = -16t² + 40t + 5

h= -16(1)² + 40(1) + 5

h= -16 + 40 + 5

h= 24 + 5

h= 29, thus, where = 1, h = 29


Using a similar sequence above, where t is
t=2; h = 21 feet; and where

t =3; h = -19



b) in this case, we must set h(t) = 0

⇒ -16t² + 40t + 5 = 0
To solve for t in the equation -16t² + 40t + 5 = 0, we can use the quadratic formula:

t = (-b ± √(b² - 4ac)) / 2a

where a, b, and c are the coefficients of the quadratic equation.

In this case, a = -16, b = 40, and c = 5, so substituting these values into the quadratic formula, we get:

t = (-40 ± √(40² - 4(-16)(5))) / 2(-16)

Simplifying:

t = (-40 ± √(1600 + 320)) / (-32)

t = (-40 ± √(1920)) / (-32)

t = (-40 ± 8 √(30)) / (-32)

t = (5/4) ± (√(30)/4)

Thus we have:

t = (5/4) + (√(30)/4) or t = (5/4) - (√(30)/4)

t₁ = 1.25 + (5.477225575051661134569697828008/4) or
t₂ = 1.25 - (5.477225575051661134569697828008/4)

t₁ = 1.25 + 1.369306393762915283642424457002
t₁ [tex]\approx[/tex] 2.6

t₂ = 1.25 - 1.369306393762915283642424457002

the length of a rectangle is 8in. more than 11 times the width. The perimeter of the rectangle is 184 inches. Find the measure of the length and width of the rectangle.

Answers

Considering the definition of perimeter, the length and width of the rectangle is 85 in and 7 in respectively.

Definition of perimeter

The perimeter of a two-dimensional figure is the distance around the figure. That is, the perimeter of a flat geometric figure is called the length of its contour.

The perimeter is the measurement obtained as a result of the sum of the sides of a flat geometric figure.

Perimeter of a rectangle

A rectangle is a geometric figure that has two pairs of sides of equal length. The expression to calculate the perimeter of a rectangle is:

Perimeter= 2× length + 2× width

Length and width of the rectangle

In this case, you know

The length of a rectangle is 8 in. more than 11 times the width. → lenght= 11×width + 8The perimeter of the rectangle is 184 inches

Replacing in the definition of the perimeter of the rectangle:

184= 2× (11×width + 8) + 2× width

Solving:

184= 2×11×width + 2×8 + 2× width

184= 22×width + 16 + 2× width

184 - 16= 22×width + 2× width

168= 24×width

168÷ 24= width

7 in= width

So, the length can be calculated as:

lenght= 11×7 in + 8 in

lenght= 85 in

Finally, the length of the rectangle is 85 in and the width of the rectangle is 7 in.

In triangle ABC, let the angle bisectors be BY and Cz. Given AB = 8, $AY = 6, and CY = 3, find BZ and BC.

Answers

Therefore , the solution of the given problem of triangle comes out to be  BZ = (8/9) * BC = 40/9 as a result.

Exactly what is a triangle?

Due to its two or more extra sections, a trapezoid is a polygon. Its shape is a simple rectangle. Only the three edges A, B, but instead C distinguish a triangle from a regular triangle. Euclidean geometry produces a singular area rather than a cube when the borders are not perfectly collinear. Triangular shapes are defined as having three sides and three angles. Angles are formed by the meeting of a quadrilateral's 3 sides.

Here,

Let D represent the intersection of the angle bisector BY and the side AC, and let E represent the intersection of the angle bisector CZ and the side AB.

=>BC² = AB² + AC² - 2AB * AC * cos(BAC)

However, since BY and CZ are angle bisectors, we can calculate BAC as follows:

=> BC² = 8² + 9² - 2(8)(9)cos[(180° - (ABC + ACB))/2]

If we simplify, we get:

=> BC² = 145 - 144cos[(ABC + ACB)/2]

Using the angle bisector theory once more, we have the following:

=> AD/DC = 8/BC

=> DC = BC(AD/8)

Simplifying and substituting into the Law of Cosines equation yields:

=> BC² = 145 - 144cos[(ABC + ACB)/2]

=>  145 - 144cos[(180° - BAC)/2]

=> 145 - 144cos(B/2)

in which B Equals ABC.

We can now replace the value of BZ that we discovered earlier with:

=> BZ = (8/9) * BC

and solve for BC:

=> BC² = 145 - 144cos(B/2)

=>  (9/8)² * (145 - 144cos(B/2)) + (8/9)² * BZ²

Simplifying and substituting BZ results in:

BC² = 25

Since BC is a length, we obtain: by taking the positive square root.

=> BC = 5

=> BZ = (8/9) * BC = 40/9 as a result.

Employees at a computer store are paid a base salary of $2,000 a month plus an 8% commission on sales over $7,000 for the month. How much must an employee sell a month to make a total of $4,000 for the month?

Answers

The employee must sell $32,000 worth of merchandise in the month to make a total of $4,000.

How to calculate the employee must sell a month to make a total of $4,000 for the month

Let's first find out how much commission an employee would earn if they sold $x in a month,

where x is the amount of sales over $7,000.

The commission earned would be 8% of x, or 0.08x.

To earn a total of $4,000 for the month, the employee would need to earn a base salary of $2,000 plus an additional $2,000 in commission.

So we can set up the following equation:

0.08x + 2000 = 4000

Subtracting 2000 from both sides, we get:

0.08x = 2000

Dividing both sides by 0.08, we get:

x = 25000

Therefore, the employee must sell $25,000 in a month to make a total of $4,000 for the month. Note that this is the amount of sales over $7,000, so the total sales for the month would be $25,000 + $7,000 = $32,000.

An open rectangular box is to be constructed by cutting square corners out of a 16​- by 16​- inch piece of cardboard and folding up the flaps. A box formed this way is shown on the right. Find the value of x for which the volume of the box will be as large as possible.

Answers

Answer:

the value of x for which the volume of the box will be as large as possible is approximately 2.67 inches.

Step-by-step explanation:

Let x be the length of the side of the squares that are cut out of the corners of the cardboard. Then the dimensions of the base of the rectangular box will be:

Length = 16 - 2x (since two squares of side x are cut out of each end of the 16-inch length)

Width = 16 - 2x (since two squares of side x are cut out of each end of the 16-inch width)

The height of the box will be x, since that is the height of the squares that were cut out.

The volume of the box can be expressed as:

V = Length × Width × Height

V = (16 - 2x) × (16 - 2x) × x

V = 4x^3 - 64x^2 + 256x

To find the value of x that maximizes the volume of the box, we can take the derivative of V with respect to x and set it equal to zero:

dV/dx = 12x^2 - 128x + 256 = 0

We can solve this quadratic equation for x using the quadratic formula:

x = [128 ± sqrt(128^2 - 4 × 12 × 256)] / (2 × 12)

x = [128 ± sqrt(16384)] / 24

x = [128 ± 128] / 24

x = 10.67 or x = 2.67

Since x represents the length of a side of a square, it must be non-negative. Therefore, the only valid solution is x = 2.67 inches.

So, the value of x for which the volume of the box will be as large as possible is approximately 2.67 inches.

Answer: Let x be the side length of the square corners that are cut out of the cardboard. Then the dimensions of the base of the box (after the corners have been cut out and the flaps folded up) are 16-2x by 16-2x, and the height of the box is x.

The volume V of the box is given by:

V = (16-2x)(16-2x)(x)

Expanding this expression gives:

V = 4x^3 - 64x^2 + 256x

To find the value of x that maximizes V, we can take the derivative of V with respect to x and set it equal to zero:

dV/dx = 12x^2 - 128x + 256 = 0

Dividing both sides by 4 gives:

3x^2 - 32x + 64 = 0

This quadratic equation can be factored as:

(3x - 16)(x - 4) = 0

So the solutions are x = 16/3 and x = 4.

Since x must be less than half of 16 (the side length of the cardboard), we can reject x = 16/3. Therefore, the value of x that maximizes the volume of the box is x = 4 inches.

The port hole in the side of a ship is in the
shape of a circle with a 2 foot diameter.
The top of the port hole is 6 feet below
the surface of the water and the density of
the water is 62.4 pounds per cubic foot.
Find the total force on this port hole due
to liquid pressure, accurate to the nearest
whole number.
[?] pounds

Answers

Answer:

the total force on the port hole due to liquid pressure is approximately 7400 pounds.

Step-by-step explanation:

The area of the circle is A = πr^2, where r = d/2 = 1 foot is the radius of the circle. So, the area is A = π(1 ft)^2 = π ft^2.

The port hole is submerged in water, with a height of 6 feet. The pressure of water at a depth of h feet is given by the formula P = ρgh, where ρ = 62.4 lb/ft^3 is the density of water, and g = 32.2 ft/s^2 is the acceleration due to gravity.

The total force on the port hole due to liquid pressure is the product of the pressure and the area of the circle, so we have:

F = P × A = ρgh × A = 62.4 lb/ft^3 × 32.2 ft/s^2 × 6 ft × π ft^2 ≈ 7400 lb

Therefore, the total force on the port hole due to liquid pressure is approximately 7400 pounds.

Jillian worked 62 hours this week and last week. She worked x hours last week and y hours this week. She worked 20% more hours this week than last week. What pair of equations can be used to find x and y?

Answers

The pair of equations that can be used to find x and y are:

x + y = 62

(1.02)x = 7

What are the pair of equations?

The form of the pair of equations would be:

hours worked last week + hours worked this week = total hours worked both weeks equation 1

(1 + percent increase/100) x hours worked last week = hours worked this week equation 2

x + y = 62 equation 1

(1 + 20/100) ×x = y

find the equation of the line using the point-slope formula. write the final equation using the slope-intercept form. (1,2) with a slope of -5/6

Answers

Answer: The point-slope formula is given by:

y - y1 = m(x - x1)

where m is the slope of the line and (x1, y1) is a point on the line.

We have a point (1,2) and a slope of -5/6. Substituting these values into the point-slope formula, we get:

y - 2 = (-5/6)(x - 1)

Expanding and rearranging this equation gives:

y - 2 = (-5/6)x + (5/6)

y = (-5/6)x + (5/6) + 2

y = (-5/6)x + (17/6)

This is the equation of the line in slope-intercept form, y = mx + b, where m is the slope (-5/6) and b is the y-intercept (17/6).

The novel Frankenstein emerged from an informal storytelling contest among Mary Shelley and her husband and friends. Originally, their purpose was simply to invent frightening tales to entertain themselves. However, Shelley's novel explores deeper themesthe dangers of unchecked curiosity, the responsibility of creating and caring for another creature, and what it means to be isolated from humanity.Shelley wrote Frankenstein nearly 200 years ago. Since then, the story of Frankenstein and his monster has been reimagined many times, in movies, television shows, and plays. Both of the main charactersthe scientist and his creationare frequently alluded to in pop songs and comic books. Some portrayals emphasize the horrific aspects of the story, while others take a more humorous tone.Identify an example from the media that presents elements of the Frankenstein story. (For instance, you might choose a movie, book, or song that features Shelley's characters.) If possible, provide a link to your example. Briefly discuss your example and address the following questions:(1) What form of media is used (television commercial, Web site, etc.)?(2) How is the Frankenstein story presented? What aspects are emphasized or downplayed? (For example, many versions present the tale as a horror story and do not portray the monster sympathetically).
