Which of the following equations describes the graph?

Answer:

96

Step-by-step explanation:

Using side b as the base, 4 points makes 3 bases (the space in between).  With three bases, you can have 3 bases of 1 segment, 2 bases of 2 segments, and 1 base of 3 segments.  This equals 6 bases. Each of these can connect to a point on line a. 6x6=36

Using side a as the base, 6 points makes 5 bases.  With 5 bases, you can have 5 bases of 1 segment, 4 bases of 2 segments, 3 bases of 3 segments, 2 bases of 4 segments, and 1 base of 5 segments.  This equals 15 bases.  Each of these can connect to a point on line b.  15x4=60

Answer:

y = -1.71x + 6.42

Step-by-step explanation:

The gradient at any point on the curve is given by the expression;

[tex]\frac{dy}{dx} = \frac{1}{\sqrt{x } - 2} \\[/tex]

At the point (2,3), the gradient of the curve will be:

[tex]\frac{dy}{dx}|(x = 2) = \frac{1}{\sqrt{ 2}-2 } \\\\\frac{dy}{dx}|(x = 2) = m = - 1.71[/tex]

The equation of this curve at this point can be given by:

[tex]y - y_1 = m(x-x_1)[/tex]

Where [tex]x_1 =2, y_1 = 3[/tex]

Substituting these values into the given equation:

[tex]y - 3 = -1.71(x-2)\\y - 3 = -1.71x + 3.42\\y = -1.71x + 3.42 + 3\\y = -1.71x + 6.42[/tex]

Answer: AB ≅ DE

∠BAC≅∠DEF

Step-by-step explanation:

as AAS is a criterion where two angles and a side not included between the angles is congruent with the other triangle's two angles and the side not included between the angles.

Detailed explanation:

The diagonals of the parallelogram must be measured in order to ascertain its name. Let's figure out these numbers:

The slope of the EF is equal to (y2 - y1) / (x2 - x1) = (-1 - (-4)) / (0 - (-2)) = 3 / 2.

Diagonal GH: [(x2 - x1)2 + (y2 - y1)2] is the length of the GH.

= √[(-5 - (-3))² + (-2 - 1)²]

= √[(-2)² + (-3)²]

= √[4 + 9] = √13

Slope of GH is equal to (y2 - y1)/(x2 - x1) = (-2 - 1)/(-5 - (-3)) = -3 / -2 = 3 / 2

Let's examine the outcomes now:

The parallelogram is a rhombus if the lengths of both diagonals are equal (EF = GH) and the slopes of both diagonals are equal (slope of EF = slope of GH).

In our case, EF = GH = √13, and the slopes of EF and GH are both 3/2. Therefore, the parallelogram is a rhombus.

Therefore, the correct answer is c) Rhombus.

For the first question, the most specific name for the parallelogram defined by the coordinates E, F, G, and H is d) Square because the lengths of the sides and the diagonals are equal.

For the second question, the statement that would prove the parallelogram PWRS is a rhombus is d) Length of QR and PS is 2.2 and Length of RS and QP is 2.2, as it shows that all sides of the parallelogram are congruent.

To determine the most specific name for the parallelogram defined by the given coordinates, we need to analyze the properties of the shape based on the lengths and slopes of its diagonals.

Let's analyze each option:

a) Rectangle: In a rectangle, opposite sides are parallel and equal in length.

Diagonals are also congruent.

To determine if the parallelogram is a rectangle, we need to find the lengths of the diagonals.

Using the distance formula, we find that the length of EF is approximately 4.47 units, while the length of GH is approximately 4.24 units.

Since the diagonals are not congruent, the parallelogram is not a rectangle.

b) Triangle: A triangle is a three-sided polygon, which is not applicable to the given parallelogram.

c) Rhombus: In a rhombus, all sides are congruent.

The diagonals of a rhombus are perpendicular bisectors of each other. To determine if the parallelogram is a rhombus, we need to compare the slopes of the diagonals.

The slope of EF is -3/2, while the slope of GH is -3/2.

Since the slopes are equal, and the lengths of the sides are not given, we cannot determine if the parallelogram is a rhombus solely based on the given information.

d) Square: A square is a special type of rectangle and rhombus, where all sides are congruent and all angles are right angles.

Since we cannot determine if the parallelogram is a rhombus, we cannot conclude that it is a square.

In conclusion, based on the given information, we cannot determine the most specific name for the parallelogram defined by the coordinates.

For the second question, to prove that the parallelogram PWRS is a rhombus, we would need to show that the lengths of the sides are congruent and that the diagonals are perpendicular bisectors of each other.

However, based on the given options, we do not have the required information to prove that PWRS is a rhombus.

Die: 16. 2/3%

Coin: 50%

Step-by-step explanation:

Well rolling a 4 on a 6 sided die is 1/6.

To make that a percent we first make it a decimal.

1 ÷ 6 = .16666 repeating

To make this a percent we move the decimal place 2 times to the right.

16.2/3%

The chance of flipping a heads on a fair sided coin is 50% because there are two sides with a 50/50 chance of being either.

Thus,

for rolling a 4 on a 6 sided die there is a 16.2/3% chance and a 50% for flipping a heads on a 2 sided coin.

Answer:

y = (3/8)x - 1.5

Step-by-step explanation:

Use the slope-intercept form y = mx + b.  Substitute -1.5 for b, 4 for x and 0 for y.  Then:  0 = m(4) - 1.5, or

4m = 1.5, or

The slope is m = 1.5/4, or m = 0.375, or m = 3/8.

Note that the x-intercept can be treated just like any other point:  (4, 0)

Then the desired equation is     y = (3/8)x - 1.5

Answer:

[tex]\boxed{y=\frac{3}{8} x-1.5}[/tex]

Step-by-step explanation:

Part 1: Determining slope from two given points

We are given the points [tex]x=4[/tex] and [tex]y=-1.5[/tex]. We can go ahead and make the first part of the equation because we are given one of the unknowns (the y-intercept, or [tex]b[/tex]). The equation becomes [tex]y=mx-1.5[/tex].

Part 2: Determine the coordinate points

[tex]x=4[/tex] is a x-intercept, meaning it crosses the x-axis at this point. The y-value is [tex]0[/tex] ⇒ [tex](4, 0)[/tex] is the first point.

[tex]y=-1.5[/tex] is a y-intercept, meaning it crosses the y-axis at this point. The x-value is [tex]0[/tex] ⇒ [tex](0, -1.5)[/tex] is the second point.

Now, plug these values into the point-slope formula: [tex]m=\frac{y_{2} -y_{1} }{x_{2}-x_{1}}[/tex]

Plug this information into the equation to get your final answer of [tex]\boxed{y=\frac{3}{8} x-1.5}[/tex].

Answer:

c. (pi*r^2)/4

Step-by-step explanation:

pi r^2 is the area of a full circle.

Divide that by two gives the area of a half circle.

Divide that by four gives the area of a quarter circle.  So

c. area of quarter circle = (pi*r^2)/4

The formula for the area of the quarter circle in the upper left corner of the figure is πr² / 4

Area is the space occupied by a flat shape or the surface of an object. Therefore,

area of a circle = πr²

where

The quarter circle is a circle divided into 4 place.

Therefore, the area of a circle needed to be divided by 4 to get the area of a quarter circle.

Answer:

The monthly cost for 9 HCF is $38.54

Step-by-step explanation:

The graph is missing; however, the question can still be solved

Given

Slope = 1.55

When monthly cost = $47.84, Amount of water = 15 HCF

Required

Determine the monthly cost for 9 HCF

From the question, we understand that it is a linear function;

Linear functions are of the form

[tex]y = mx + b[/tex]

Where y is the function of x and m is the slope

In this case; the function is the monthly water bill

and x is the amount of water

Solving for b

When monthly cost = $47.84, Amount of water = 15 HCF

The function is as follows;

[tex]47.84 = 1.55 * 15 + b[/tex]

[tex]47.84 = 23.25 + b[/tex]

Subtract 23.25 from both sides

[tex]47.84 - 23.25= 23.25 - 23.25 + b[/tex]

[tex]24.59 = b[/tex]

[tex]b = 24.59[/tex]

Solving for the monthly cost for 9 HCF

Here, we have that

[tex]x = Amount\ of\ water = 9[/tex]

[tex]m = Slope = 1.55[/tex]

[tex]b = 24.59[/tex]

Substitute these values in the linear function; [tex]y = mx + b[/tex]

[tex]y = 1.55 * 9 + 24.59[/tex]

[tex]y = 13.95 + 24.59[/tex]

[tex]y = 38.54[/tex]

Hence, the monthly cost for 9 HCF is $38.54

This indicates that the point of intersection is: (8,-6)

Step-by-step explanation:

The intersection of two lines is the point where they intersect. The point where the line crosses the x axis is called [x-intercept]. The point [y-intercept] is where the line crosses the y-axis.

The point of intersection is calculated by equating their equations. By solving the resulting equation, the coordinates of the cut point are obtained.

In this case you have y=14−2.5x and y=1.5x−18

Equating the equations you get:

14-2.5x=1.5x-18

Solving:

14+18=1.5x+2.5x

32=4x

32÷4=x

x=8

Replacing in both equations: y=14-2.5*8=-6

y=1.5*8-18=-6

This indicates that the point of intersection is: (8,-6)

The intersection point can be seen graphically, representing both lines, as shown in the attached image, where the red line is y = 14−2.5x and the blue line represents y =1.5x-18

Answer:

11 pounds of Guatemala Antigua coffee

9 pounds of Arabian Mocha coffee

Step-by-step explanation:

Guatemala Antigua coffee - $10.20 per pound

Arabian Mocha coffee - $13.00 per pound

First find the total profit from the 20 pounds of the new coffee blend.

20 × $11.46 = $229.20

$10.20g + $13.00a = $229.20

Use guess and check to find the number of pounds of each type of coffee.

$10.20g + $13.00a = $229.20

$10.20(11) + $13.00(9) = $229.20

$112.20 + $117 = $229.20

$229.20 = $229.20

It checks out. So, they should mix 11 pounds of Guatemala Antigua coffee and 9 pounds of Arabian Mocha coffee.

Answer:

3.43

Step-by-step explanation:

To do this you would first find the area of the square which is 16. Then you would find the area of the 2 semicircle or just on whole circle. We are just going to use the formula for a whole circle since there are 2 semicircles. The formula to find a circle is pi times r^2 so we are going to put that into a calculator so we would do pi times 2 (radius of circle)^2 which is 12.57 and we would subtract 16 by 12.57 which is 3.43

Answer:

3.44 units^2

Step-by-step explanation:

Area of a square = l * w

Area of a circle = 3.14 * r^2

Area of semicircle = 3.14 * r^2 * 1/2

Area of shaded region: Area of square - Area of 2 semicircles

Area of square => 4 * 4 = 16

Area of both semicircles => (3.14 * r^2 * 1/2)*2 = 12.56

16 - 12.56 = 3.44

3.44 units^2 is the answer

Let's look back at the history of the world and reflect on some of the great new methods of transportation that have been invented. There were cars, motorbikes, cycles, carriages, trains, boats, carts and horseback. Cycles have by far been the most economical and productive to use. The first was made in 1817 by Karl von Drais. Since then, many improvements and changes have been made to the original design, like making equally sized wheels, adding rubber tires, etc.

Answer:

Cycling, also called bicycling or biking, is the use of bicycles for transport, recreation, exercise or sport. People engaged in cycling are referred to as "cyclists", "bicyclists", or "bikers". Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadracycles, recumbent and similar human-powered vehicles (HPVs).

Bicycles were introduced in the 19th century and now number approximately one billion worldwide. They are the principal means of transportation in many parts of the world.

Cycling is widely regarded as a very effective and efficient mode of transportation optimal for short to moderate distances.

Bicycles provide numerous benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, and access to roads, bike paths and rural trails. Cycling also offers a reduced consumption of fossil fuels, less air or noise pollution, and much reduced traffic congestion. These lead to less financial cost to the user as well as to society at large (negligible damage to roads, less road area required). By fitting bicycle racks on the front of buses, transit agencies can significantly increase the areas they can serve

In addition, cycling provides a variety of health benefits. The World Health Organization (WHO) states that cycling can reduce the risk of cancers, heart disease, and diabetes that are prevalent in sedentary lifestyles. Cycling on stationary bikes have also been used as part of rehabilitation for lower limb injuries, particularly after hip surgery. Individuals who cycle regularly have also reported mental health improvements, including less perceived stress and better vitality.

Among the disadvantages of cycling are the requirement of bicycles (excepting tricycles or quadracycles) to be balanced by the rider in order to remain upright, the reduced protection in crashes in comparison to motor vehicles, often longer travel time (except in densely populated areas), vulnerability to weather conditions, difficulty in transporting passengers, and the fact that a basic level of fitness is required for cycling moderate to long distances.

Answer:

1.5 meters

Step-by-step explanation:

We know that the sum of all of the data in a set = average * number of data.

Therefore, the sum of the first 10 is 1.5 * 10 = 15 meters, the sum of the second 10 is 1.48 * 10 = 14.8 meters and the sum of the last 2 is 1.6 * 2 = 3.2 meters for a total of 15 + 14.8 + 3.2 = 33 meters. This means that the mean is 33 / 22 = 1.5 meters.

Answer:

Hey there!

We have the average is: [tex]\frac{10(1.5)+10(1.48)+2(1.6)}{22}[/tex]

This can be simplified to: 33/22, or 1.5

Thus, the mean height on the team is 1.5 m.
