Answer:

Option A: T(-3, -4)

Step-by-step explanation:

For a general point (x, y), if we apply the transformation:

T(a, b)

at that point, the new point that we will get is:

T(a,b)[ (x, y) ] = (x + a, y + b)

Notice that if w take the difference between the new point (x + a, y + b) and the original point (x, y)

we get:

(x + a, y + b) - (x, y) = (x + a - x, y + b  y) = (a, b)

These are x-value and y-value that describe our transformation T(a, b).

Then if we know that the original point is B (-2, 1)

and the transformed point is B'( -5, -3)

We can just take the difference to get:

(-5, -3) - (-2, 1) = (-5 - (-2), -3 - 1) = (-5 + 2, -4) = (-3, -4)

Then the transformation applied is:

T(-3, -4)

The correct option is A.

The selection depends on individual needs, preferences, and the intended use of the tiny house.

a) To find the amount of space inside each house, we need to calculate the volume for each design.

House on the left:

Volume = length x width x height = 2.5 m x 18 m x 2.8 m = 126 m³

Triangular house:

Volume of a triangular prism = (base area x height) / 2

Base area = (1/2) x base x height = (1/2) x 4 m x 10 m = 20 m²

Volume = (20 m² x 7 m) / 2 = 70 m³

b) When comparing the environmental impacts of each house, several factors need to be considered:

Positive impacts:

1. Material usage: Tiny houses use fewer materials, reducing resource consumption and waste generation.

2. Energy efficiency: Smaller living spaces require less energy for heating, cooling, and lighting, leading to lower energy consumption.

3. Land utilization: Tiny houses can be built on smaller plots of land, preserving green spaces and reducing urban sprawl.

Negative impacts:

1. Construction materials: Although tiny houses use less material overall, the environmental impact depends on the types of materials used. Sustainable and eco-friendly materials should be prioritized.

2. Water and waste management: Adequate provisions for water supply and waste disposal should be implemented to minimize environmental impacts.

3. Transportation: The transportation of tiny houses to their locations can contribute to carbon emissions if not done efficiently.

c) The choice of design for a tiny house depends on personal preferences and priorities. However, considering the provided information:

The house on the left offers a larger interior space of 126 m³, providing more room for living and storage. It may be suitable for individuals or couples who desire more space and functionality within their tiny house.

The triangular house has a smaller interior volume of 70 m³ but offers a unique design and aesthetic appeal. It may be preferred by individuals who prioritize a distinctive architectural style or who are looking for a minimalist and cozy living space.

Ultimately, the selection depends on individual needs, preferences, and the intended use of the tiny house. Factors such as lifestyle, desired amenities, and personal values regarding sustainability and resource conservation should be considered when making the final decision.

If The ratio of the mass of the fruit to the mass of the yoghurt is 2:3 the mass of the yogurt is 99 g,

Let's assume the mass of the fruit is 2x and the mass of the yogurt is 3x, where x is a common factor.

According to the problem, the total mess of the desert is 165 g, so we can write an equation:

2x + 3x = 165

Simplifying this equation, we get:

5x = 165

x = 33

Therefore, the mass of the fruit is:

2x = 2(33) = 66 g

Answer:

73 degrees.

Step-by-step explanation:

the inward angle at W is the outward angle at Y and therefore the complement of 107 degrees to 180.

180 - 107 = 73 degrees.

The measure of angle ZWX is 73 degrees.

Any closed figure made by 4 line segments joined end to end in series is called a quadrilateral.

We are given that the trapezoid WXYZ, m∠ZYX=107°.

We have been given an image of a trapezoid and we are asked to find the measure of angle ZWX .

We can see from our trapezoid that angle XYZ and angle WZY measures 90 degrees.

Since we know that trapezoid is a quadrilateral and sum of all angles of a quadrilateral equals

m∠ZYX + m∠ZWX = 180

m∠ZWX = 180 - 107

m∠ZWX = 73 degrees.

Answer:

A book was 53 pages shorter than you expected

Jennifer sold 53 apples.

Andrew spent $53.

Step-by-step explanation:

The question proposed that we should determine which situation can be said to be the opposite of 53. From the listed option, we will realize that the following:

A book was 53 pages shorter than you expected

Jennifer sold 53 apples.

Andrew spent $53.

The above options are the opposite of 53. This is because a book that was shorter than expected will need to be refilled.

Suppose Jennifer has x apples, and She sold 53 apples out of it. It means x = -53, which is the opposite of 53.

Andrew spent $53; let say Andrew had y+$53. After spending $53, he has y = - $53, which is the opposite of 53.

But the temperature, which was 53°F, will still be at that position on the thermometer provided it is not being affected by external conditions.

A graph of the image of triangle V'W'X' after a rotation of 90° counterclockwise about the origin is: graph A.

A rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.

In Geometry, rotating a point 90° about the origin in a counterclockwise (anticlockwise) would produce a point that has the coordinates (-y, x).

Note: Each interval on this graph represents 1 unit.

By applying a rotation of 90° counterclockwise to triangle VWX, the coordinates of the vertices of the image triangle V'W'X' include the following:

(x, y)                    →            (-y, x)

Point V = (-2, -4)   →     Point V' = (-(-4), -2) = (4, -2)

Point W = (-2, -2)   →    Point W' = (-(-2), -2) = (2, -2)

Point X = (-5, -4)   →  Point X' = (-(-4), -5) = (4, -5)

Both parts (a) and (b) have the same number of ways to arrange the smoothies, which is 21! (21 factorial).

(a) To arrange 21 indistinguishable strawberry smoothies in a 21x21 grid such that no two smoothies are in the same row or column, we can consider the problem as placing 21 objects (smoothies) into 21 slots (grid compartments).

The first smoothie can be placed in any of the 21 slots in the first row. Once it is placed, the second smoothie can be placed in any of the 20 remaining slots in the first row or in any of the 20 slots in the second row (excluding the column where the first smoothie is placed). Similarly, the third smoothie can be placed in any of the 19 remaining slots in the first or second row or in any of the 19 slots in the third row (excluding the columns where the first and second smoothies are placed), and so on.

Therefore, the total number of ways to arrange the strawberry smoothies in the grid without repetition is:

21 * 20 * 19 * ... * 3 * 2 * 1 = 21! (21 factorial).

(b) In this case, Luciano has 21 distinct smoothies to arrange in the 21x21 grid such that no two smoothies are in the same row or column.

The first smoothie can be placed in any of the 21 slots in the first row. Once it is placed, the second smoothie can be placed in any of the 20 remaining slots in the first row or in any of the 20 slots in the second row (excluding the column where the first smoothie is placed). Similarly, the third smoothie can be placed in any of the 19 remaining slots in the first or second row or in any of the 19 slots in the third row (excluding the columns where the first and second smoothies are placed), and so on.

where h is the height of the jump and g is the acceleration due to gravity.

The required details for equation in given paragraph

An equation is a formula that expresses the equality of  expressions, with the aid of using connecting them with the equals signal =. The word equation and its cognates in different languages can also additionally have subtly extraordinary meanings; for example, in French an équation is described as containing one or more variables, whilst in English, any well-shaped formula which includes expressions associated with an equals signal is an equation. Solving an equation containing variables includes figuring out which values of the variables make the equality true. The variables for which the equation must be solved also are called unknowns, and the values of the unknowns that fulfill the equality are called solutions of the equation.

This equation is based on the kinematic equation for vertical motion with constant acceleration, which states that the time it takes for an object to fall a distance h under the influence of gravity is given by the formula:

Answer:

x ≤ 207 crates

Step-by-step explanation:

Greatest weight of the container = 27,500 kilograms

Weight of other shipment = 6,800 kilograms

Weight of a crate = 100 kilograms

Number of 100-kilogram crates that can be loaded into the shipping container = x

The inequality is

27,500 ≤ 6800 + 100x

27,500 - 6800 ≤ 100x

20,700 ≤ 100x

x ≤ 20,700 / 100

The solution of the differential equation dy/dx=\(2xy/(x^{2} -1)\) is y=\(-x^{2} +1\).

Given a differential equation dy/dx=\(2xy/(x^{2} -1)\).

We are required to find the solution of the differential equation when y(0)=1.

dy/dx=\(2xy/(x^{2} -1)\)

Taking y to left side and dx to right side.

1/y dy=2x/\((x^{2} -1)\) dx

Integrating both sides.

\(\int\limits {1/y} \, dy\)=\(\int\limits {2x/(x^{2} -1)} \, dx\)----------1

log y=\(\int\limits {2x/(x^{2} -1)} \, dx\)

Solving right side.

\(\int\limits {2x/(x^{2} -1)} \, dx\)

let \(x^{2} -1\)=z

differentiating both sides with respect to x.

2x=dz/dx

2x dx=dz

Put 2x dx=dz in 1.

\(\int\limits {1/y} \, dy\)=\(\int\limits {1/z } \, dz\)

log y=log z+log c

Put z=\(x^{2} -1\)

log y=log(\(x^{2} -1\))+log c

log y=log [{\(x^{2} -1\))c]

y=(\(x^{2} -1\))c------------2

Put x=0 and y=1

1=(0-1)c

1=-c

c=-1

Put c=-1 in 2 to get the solution.

y=-1(\(x^{2} -1\))

y=\(-x^{2} +1\)

Hence the solution of the differential equation dy/dx=\(2xy/(x^{2} -1)\) is

y=\(-x^{2} +1\).
