A regular hexagon with a perimeter of 45 meters is dilated by a scale factor of 4/3 to create a new hexagon. What is the perimeter of the new hexagon?

Answers

Answer 1

The perimeter of the resulting hexagon is 60 meters.

What is the perimeter of the image of a hexagon as a result of a dilation?

In this problem we find the perimeter of a regular hexagon, which is dilated around its center. Regular hexagons are polygons with six sides of equal length. Dilations are rigid operations of the form:

P'(x, y) = O(x, y) + k · [P(x, y) - O(x, y)]

Where:

O(x, y) - Center of dilation.k - Scale factorP(x, y) - Original pointP'(x, y) - Resulting point

The perimeter is the sum of the side lengths of the hexagon and by dilation we find the following relationship between original and resulting perimeters (p, p'):

p' = k · p

If we know that p = 45 and k = 4 / 3, then the resulting perimeter is:

p' = (4 / 3) · (45)

p' = 60

The resulting hexagon has a perimeter of 60 meters.

The domain and range of the relation shown in the table include the following: A. domain:{−3, −1, 2, 4}, range:{0, 2, 4}.

What is a domain?

In Mathematics, a domain can be defined as the set of all real numbers for which a particular function or relation is defined.

This ultimately implies that, a domain is the set of all possible input values (x-values) to a relation, and the domain of a graph comprises all the input values which are located on the x-coordinate from the least to the greatest.

Additionally, a range is the set of all real numbers that is associated with the elements of a domain i.e all of the y-values shown on the y-coordinate of the graph of a relation, from the least to the greatest.

By critically observing the table of this relation shown, we can reasonably infer and logically deduce the following:

Domain = {−3, −1, 2, 4}.

Range = {0, 2, 4}.

Lower Limit = 24.52

Upper Limit = 36.28

Error Bound = 5.88

Lower Limit: - The Lower Limit for every class is the smallest value in that class. For example: 5 is a lower lower limit for the set S= { 5,8,42,34}

Upper Limit: - A value that is greater than or equal to every element of a set of data. For example: - { 3,5,11,20,22} is a upper bound of 22.

Given that,

Population Mean,μ = 33.2

α (Alpha) = 0.05

Population standard deviation,σ = 15

Zach loves to compete in triathlons. At a race a few months ago, he finished in 280 minutes. Yesterday, he completed another triathlon and finished in 294 minutes. What was the percent of increase in Zach's finishing time?

Answers

The percent of increase in Zach's finishing time is 5%.

How to calculate the percentage?

From the information, at a race a few months ago, he finished in 280 minutes and yesterday, he completed another triathlon and finished in 294 minutes.

The increase in time will be:

= New time - Old time

= 294 - 280

= 14 minutes

The percentage increase will be:

= Increase in time / Original time × 100

= 14 / 280 × 100

= 1/20 × 100

= 5%

1) [tex]1.4^{2}[/tex] is really just 1.4 * 1.4, which you can solve by long multiplication or a calculator to get 1.96

2) for this one, you can rewrite the expression as a fraction. you'll also want to use PEMDAS, starting with the parentheses

[tex]\frac{300}{ 2(0.5+4.5)^{2}}\\\\\frac{300}{2*(5)^2}\\\\\frac{300}{2*25} \\\\\frac{300}{50} = 6[/tex]

julia rides her bike at a rate of 1/2 mile per 1/9 of an hour. how far does she ride in one hour

Answers

Answer:

4.5 miles

Step-by-step explanation:

0.5 of a mile per 1/9 of an hour.

rate x time=distance and you need to find distance for one hour not 1/9 so multiply it by 9 so

0.5*9=4.5, 1/9*9=1

rate   time   distance

4.5  *    1   =  d

4.5*1=d

4.5=d

so the distance traveled in one hour is 4.5 miles

Answer:

4.5 miles

Step-by-step explanation:

Given:

Julia rides her bike at a rate of 1/2 mile per 1/9 of an hour.

Let x be the distance Julia rides in one hour.

Create an equivalent ratio of miles to hours:

[tex]\implies \dfrac{1}{2}:\dfrac{1}{9}=x:1[/tex]

[tex]\implies \dfrac{\frac{1}{2}}{\frac{1}{9}}=\dfrac{x}{1}[/tex]

[tex]\implies \dfrac{1}{2}\times \dfrac{9}{1}}=x[/tex]

Answers

The price range of the Chevrolet HHR retro will be $14,500.

What is the range of the data?

The range of the data is defined as the difference between the maximum value of data and the minimum value of the data.

The given data as:

$8,500, $8,500, $8,500, $9,900, $10,800, 10,800, 11,000, 12,500, $12,500, $13,000, 13,000, $14,500, and $23,000

According to the given information, the required solution would be as:

The maximum value of data = $23,000

The minimum value of data = $8,500

The range of the data = The maximum value of data - The minimum value of data

Substitute the values in the above formula,

The range of the data = 23,000 - 8,500

Apply the subtraction operation to get the answer

The range of the data = 14,500

Therefore, the price range of the Chevrolet HHR retro will be $14,500.

If r(x) = 2x² and w(x) = x-2, what is the range of (wor)(x)?

Answers

The given function are

r(x) = 2 - x²    and     w(x) = x - 2

(w*r)(x) can be obtained by multiplying the both function together

So, (w*r)(x) = w(x) * r(x) = (x-2)*(2-x²)

(w*r)(x) = x (2-x²) - 2(2-x²)

           = 2x - x³ - 4 + 2x²

∴ (w*r)(x) = -x³ + 2x² + 2x - 4

It is a polynomial function with a domain equal to R

The range of (w*r)(x) can be obtained by graphing the function

To graph (w*r)(x), we need to make a table between x and (w*r)(x)

See the attached figure which represents the table and the graph of (w*r)(x)

As shown in the graph the range of (w*r)(x) is (-∞,∞)

The surface area of a square pyramid is 96 square feet. The height is two-thirds of the length of the base edge.

What is the length of the base edge?

Answers

The length of the base edge of the pyramid is 1.71 feet

What is surface area of a pyramid?

In order to find the total surface area, we will need to add up the areas of the base and the three other sides. SA=B+12(P×h), where B is the area of the base of the pyramid, P is the perimeter of the base, and h is the slant height of the pyramid.

If l is the length of the square base and h is the height of the pyramid, then h =2/3l

from the formula, SA= B+12(P×h)

the perimeter of a square is 4l

the base area of square is l^2

therefore 96= l^2+ 12(4l×2/3l)

96= l^2+ 12×8/3l^2

96=l^2+32l^2

96= 33l^2

divide both sides by 33

l^2= 96/33

l=√2.91

l=1.71 feet
