Geometry: Transformations
Other than translation, what transformation is used to create this frieze pattern?
A) vertical reflection
B) horizontal reflection
C) glide reflection
D) 180° rotation

Answer:

Step-by-step explanation:

Our equation is

\(b(t)=x(2)^t\) where x is the initial amount and the growth rate is 2 (doubling). t is time in hours.

For part b

\(3x=x(2)^t\) which is asking how long it will take for the initial x amount of bacteria to grow to 3 times in size.

Divide both sides by x to get

\(3=2^t\) then take the ln of each side in order to bring down the t from its exponential position:

\(ln(3)=t*ln(2)\)

Divide both sides by ln(2) to get the value for t on your calculator.

t = 1.58 hours

The exact duplication of elements on either side of a central axis is called symmetry. Symmetry refers to the property of an object or system where it exhibits a precise duplication of elements on either side of a central axis or plane.

This duplication can occur in various forms, such as shapes, patterns, or structures. Symmetry is a fundamental concept in mathematics, art, design, and science. It is often studied and utilized to create aesthetically pleasing compositions, identify patterns, and analyze the properties of objects.

Symmetry can be classified into different types, such as bilateral symmetry (reflectional symmetry) where the object is identical on both sides of a vertical axis, or radial symmetry where the object is identical around a central point.

The concept of symmetry plays a significant role in diverse fields, including geometry, biology, crystallography, and physics.

Answer:

C ) 4 x + 8

Step-by-step explanation:

( 24 x + 48 ) / 6

4 x + 48

The length of a regular hexagon is:

4x ₊ 8

How many sides do a hexagon have? How do we calculate the length and parameter of it?

A regular hexagon have six sides.

The area of a regular hexagon can be calculated using the formula (33 s2)/2, where s is the side length. The lengths of all six sides of a hexagon can be added to determine its perimeter. Perimeter = 6 s, where s is the length of one side, is the formula used to determine the size of a regular hexagon.

Solution:

Given,

parameter of a hexagon = 24x ₊ 48

length of one side of a hexagon s = p ÷ 6

                                                  s = 24x ₊ 48 ÷6

                                                  s = 4x ₊ 8

Hence we get the length of one side as 4x ₊ 8

The relative frequency as a percentage is 25.7%.

The ratio (fraction or proportion) of the number of times a data value appears in the set of all outcomes to the total number of outcomes is known as the relative frequency. Divide each frequency by the overall sample size, in this example 20 students, to determine the relative frequencies.

The relative frequency of students who picked either butterflies or trains as their favorite exhibit is 18 (12 + 6) out of a total of 70 students.

The relative frequency as a percentage is 18/70 * 100 = 25.7%.

Answer:

The answer should be $3.125 or $3.13 rounded.

Step-by-step explanation:

First I divided 1.25 by 100 because 1 meter equals 100 centimeters.

1.25 ÷ 100 = 0.0125

Now that we know that it costs 0.0125 for 1 centimeter we multiply it by 250.

0.0125 * 250 = 3.125

Since it says to round to the nearest cent, the answer should be 3.13

Statistics computed for larger random samples tend to be less variable compared to statistics computed for smaller random samples.

This statement is based on the concept of the Central Limit Theorem (CLT) in statistics. According to the CLT, as the sample size increases, the distribution of the sample mean approaches a normal distribution regardless of the shape of the population distribution. This means that the variability of the sample mean decreases as the sample size increases.

The variability of a statistic is commonly measured by its standard deviation or variance. When working with larger random samples, the individual observations have less impact on the overall variability of the statistic. As more data points are included in the sample, the effects of outliers or extreme values tend to diminish, resulting in a more stable and less variable estimate.

In practical terms, this implies that estimates or conclusions based on larger random samples are generally considered more reliable and accurate. Researchers and statisticians often strive to obtain larger sample sizes to reduce the variability of their results and increase the precision of their statistical inferences.

The standard deviation of the sampling distribution is called the standard error of the mean, not the median. The standard error of the median is a different measure that is used to estimate the variability of the median of a sample.

When we take a sample from a population, the values of the sample statistics, such as the mean, median, standard deviation, etc., will vary from sample to sample. The distribution of the sample statistics is called the sampling distribution.

The standard deviation of the sampling distribution of the mean is called the standard error of the mean. It is a measure of the variability of the sample means from sample to sample.

The population of your friend's town is 300,000 if the population of your town is about 30,000.

To solve this problem, we can use the fact that if one quantity is a fraction of another quantity, we can multiply or divide the given quantity by that fraction to find the other quantity. In this case, we know that the population of your town is 1/10th of your friend's town's population, so we can multiply your town's population by 10 to get your friend's town's population.

If the population of your town is about 30,000, and it's about 1/10 the population of your friend's town, we can calculate your friend's town's population by multiplying your town's population by 10.

So, the population of your friend's town is

30,000 x 10 = 300,000

Therefore, your friend's town has a population of about 300,000.

Answer:

iPhone 8+ (2017) 736 × 414 1920 × 1080 16:9 3× 5.5″ 401 PPI

Step-by-step explanation:

a. Dimensions of the screen

The dimensions of the screen are height = 2.7 in and width = 4.8 in

Since the aspect ratio is the ratio of width, w to height, h of the iPhone 8 and it is 16:9, we have that

w/h = 16/9

w = 16h/9

Also, the diagonal length, d = 5.5 inches.

Since the iPhone 8 screen is a rectangle, the diagonal length d is gotten from pythagoras' theorem.

So, d = √(w² + h²)

Since w = 16h/9

d = √(w² + h²)

d = √((16h/9)² + h²)

d = h√((16/9)² + 1²)

d = h√(256/81 + 1)

d = h√[(256 + 81)/81]

d = h√[337/81]

d = h√4.16

d = 2.04h

Making h subject of the formula, we have

h = d/2.04

h = 5.5/2.04

h = 2.7 in

So, w = 16h/9

w = 16 × 2.7 in/9

w = 43.2 in/9

w = 4.8 in

So, the dimensions of the screen are height = 2.7 in and width = 4.8 in

b. Number of pixels per inch

The number of pixels per inch (PPI) is 400 pixels per inch

To find the number per inch, we need to find the total number of pixels on the screen which is 1080 by 1920 = 2073600 pixels.

The area of the screen is A = wh

= 4.8 in × 2.7 in

= 12.96 in²

So, the number of pixels per square inch (PPI²) is 2073600 pixels/12.96 in² = 160000 pixels/in².

So, pixels per inch(PPI) = √160000 pixels/in²

= 400 pixels per inch

So, the number of pixels per inch (PPI) is 400 pixels per inch

Answer:

He earned $852 from the gumballs he sold.

Step-by-step explanation:

It says he sold 20 boxes and there are 45 pieces of candy in each box so you multiply 20 and 45 and you will get 900 so they had sold 900 pieces of candy. And from the lollipops he earned $948 the you divided by 2 cause that is how much each piece cost and that gets you 474, which are how many lollipops he sold. So now that you have the amount of lollipops he sold you have to subtract that from the total amount of candy he had, which is 900, so minus 474 from that and you get 426 pieces of gum that were sold and then multiply that by 2 because it cost 2 dollars for each piece and you get $852.
