In order to dilate something on a coordinate plane, multiply the coordinate with the scale factor. This process is known as mapping.

What is a dilation?

Dilation is a process of altering a thing. It is a process of renewal that to make the objects smaller or larger, with the use of specific scale factor.

The new figure that is the result of dilation is known as the image. Initial figure is referred to as the pre-image.

What is a center of dilation?  

Center of dilation is the resizing that happens from a point. The objects/figures are expanded or contracted from the center of dilation.

Scale factor is a figure by which the size of any geometrical figure can be resized, with respect to its original size. The scale factor is multiplied to get image.

The area of figure will change quadratically in proportion to length squared when a scale factor is applied

A scale factor is simply a number that multiplies a shape's dimensions. This can enlarge a shape. The scale factor for larger shapes will be greater than one. So, if the scale factor is three, the new shape's dimensions will be three times larger than the original.

A scale factor can also reduce the size of a shape. Smaller shapes have a scale factor that is less than one.

When you dilate a figure, it becomes larger or smaller

With a certain factor, the length of its sides either increases or decreases.

As a result, a change in length will affect the total area of the figure with that scale factor.

the answer is b the arrow BD make angels equal in both sides

The solution is

The width of the rectangular aluminum foil whose area is 11 1/4 inches is

2 1/2 inches

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the width of the aluminum foil be represented as = W

Now , the equation will be

The area of the aluminum foil is A = 11 1/4 inches²

The value of A = 11 1/4 inches²

The value of A = 45/4 inches²

Now ,

The length of the aluminum foil L = 4 1/2 inches

The value of L = 4 1/2 inches

The value of L = 9/2 inches

Now , from the equation of area of rectangle

Width of the rectangle W = Area of rectangle A / Length of rectangle L

Substituting the values in the equation , we get

Width of the aluminum foil W = ( 45/4 ) / ( 9/2 )

Width of the aluminum foil W = ( 45/4 ) x ( 2 / 9 )

Width of the aluminum foil W = 5 / 2 inches

Width of the aluminum foil W = 2 1/2 inches

Therefore , the value of W is 2 1/2 inches or 5/2 inches

Hence , The width of the rectangular aluminum foil is 2 1/2 inches

What is combination?

A combination is a choice made in mathematics from a group of different elements when the order of the choices is irrelevant (unlike permutations). For instance, if three fruits, such as an apple, an orange, and a pear, are supplied, there are three possible pairings of the two: an apple and a pear. Formally speaking, a k-combination of a set S is a subset of S's k unique components. In other words, two combinations are the same if and only if they have the same members.

The side opposite the larger angle is larger and you know that MN>NP, so the angle O's measure is more than the angle Q's measure.

Describe angle.

Two rays that have a common terminal and are referred to as the angle's sides and vertices, respectively, make up an angle in Euclidean geometry. Two rays can form angles in the plane where they are positioned. Angles are also produced when two planes intersect. These are what are known as dihedral angles.

Here,

Greater is the side that is on the other side of the greater angle.

MN>NP.

Consequently, the measure of angle O is greater than angle Q's measure.

Option D is correct since MN>NP is true and the side that opposes the bigger angle is larger. The measure of angle O is therefore greater than the measure of angle Q.

Answer:

the volume of the space left in the larger box for packing materials is 1000 - 512 = 488 cubic inches.

Step-by-step explanation:

To find the volume of the space left in the larger box for packing materials, we first need to calculate the volume of the smaller cube and then subtract it from the volume of the larger box. The volume of a cube with side length s is given by s^3, so the volume of the smaller cube with side lengths of 8 inches is 8^3 = 512 cubic inches. The volume of the larger box with side lengths of 10 inches is 10^3 = 1000 cubic inches

The angle B for the triangle ABC has a measure of 118° so the correct option is 118°.

The angle B and its exterior angle lie on a straight line, thus their sum is equal to 180°

From the question, we are given that;

m∠B = (12x − 26)° and the exterior angle = (7x − 22)°

so;

12x - 26 + 7x - 22 = 180° {collect like terms}

19x - 48 = 180°

19x = 180° + 48° {add 48° to both sides}

19x = 228°

x = 228°/19 {divide through by 19}

x = 12

Therefore, by putting the value 12 for x in m∠B = (12x − 26) we get the angle B as;

B = 12(12) - 26

B = 144 - 26

B = 118°

In conclusion, the triangle ABC, with m∠B = (12x − 26)° and the measure of the exterior angle to ∠B is (7x − 22) have the angle B equal to 118°.

Solving the word problems, Sandy has 1.5 more bucket of apple than Keith and Jayson has saved 15/4 month of worth pay

This is often a mathematical problem expressed entirely in words typically used as an educational tool.

To solve this type of problem, we have to translate the words into algebraic expressions or equations and solve for the unknown variables.

1)

Keith = 2 5/6 bucket of apples

Sandy = 4 1/3 bucket of apples

We have to convert this from mixed fractions into improper fraction

Keith = 2 5/6 = 17/6 bucket of apples

Sandy = 4 1/3 = 13/3 bucket of apples

To determine how many more bucket of apples Sandy picked than Keith, we simply need to subtract the fractions from one another.

13/3 - 17 / 6 = 3/2 = 1.5

Sandy picked 1.5 more than Keith

2)

To determine how much Jayson has, we simply need to sum up all his money which will be

Yellow Taxi service charges a $15 flat fee plus $2.50

This means that

Yellow Taxi: y = 15 + 2.5x

For the graph, we have

y-intercept = 10

(x, y) = (0, 10) and (2, 16)

So, the slope is

slope = (y₂ - y₁)/(x₂ - x₁) = (16 - 10)/(2 - 0) = 3

So, we have

Black and White Taxi service: y = 10 + 3x

Yellow Taxi: y = 15 + 2.5x

When he travels for 5 miles, we have

Black and White Taxi service: y = 10 + 3 * 5 = 25

Yellow Taxi: y = 15 + 2.5 * 5 = 27.5

Hence, the least amount possible is $25

This means that we equate the above equations

So, we have

15 + 2.5x = 10 + 3x

We need to use 7 terms to estimate the value of ln(1.4) to within 0.0001.

A Maclaurin series is a function that is used to estimate the values functions, evaluate the sum, or determine the value of the anti-derivative of a function.

We have:

f(x)=ln(1+x)

Expansion of In(1+x) up to seven terms is:

In(1+x) = x - x^2/2 + x^3/3 - x^4/4 + x^5/5 - x^6/6+ x^7/7

Where it is known that -1 <= x <= 1

Put x=0.4 in the above series:

ln(1.4) = 0.4 - 0.4^2/2 + 0.4^3/3 - 0.4^4/4 + 0.4^5/5 - 0.4^6/6+ 0.4^7/7

The time taken to reach $1000000 with an interest rate in a mutual fund of 8% compounded monthly is about 64 years and 2 months.

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

P = $6000

r = 8%

n = 12

A = $1000000

Now,

1000000 = 6000 [tex](1 + 0.08/12)^{12t}[/tex]

1000/6 = [tex]1.0067^{12t}[/tex]

The linear function is defined in the slope-intercept format, as follows:

y = mx + b.

In which:

Considering the data for 2009 and for 2017 from the table, taking x as the number of years since 2005, two points are given as follows:

(4,175) and (12, 189).

The slope, given two points, is calculated as the division of the change in y divided by the change in x, hence:

m = (189 - 175)/(12 - 4) = 14/8 = 1.75.

Hence:

y = 1.75x + b.

When x = 4, y = 175, hence the intercept b is calculated as follows:

175 = 1.75(4) + b

b = 168.

Then the line of fit is:

y = 1.75x + 168.
