Find the direction angle of the vector v = 2i -6j

The area of a two-dimensional cross-section depends on the shape it represents, such as a square, rectangle, triangle, circle, or any other polygon. Each shape has its own formula for calculating its area.

In order to determine the area of the cross-section, we need additional information such as the shape of the cross-section, its dimensions, or any other relevant details. Without this information, it is not possible to calculate the area. Please provide more details or a specific shape or scenario so that an accurate answer can be generated. Once the shape is specified, the appropriate formula can be applied to calculate the area.

\(( {2x)}^{3} - {(2)}^{3} \)

Use the formula:

\( {a}^{3} - {b}^{3} = (a + b)( {a}^{2} - ab + {b}^{2} )\)

The rule for the translations can be written as T -3,1(x,y).

The rule for translations can be written as (x,y)➡️(x-3,y+1).

Step-by-step explanation:

I just took the test

Translation involves changing the position of a shape.

The true options are:

From the question, we have the following vertices of the first and the second triangles.

\(\mathbf{A = (-1,-2)}\)

\(\mathbf{B = (1,-2)}\)

\(\mathbf{C = (2,-5)}\)

\(\mathbf{D = (-2,-5)}\)

\(\mathbf{A' = (-4,-1)}\)

\(\mathbf{B' = (-2,-1)}\)

\(\mathbf{C' = (-1,-4)}\)

\(\mathbf{D' = (-5,-4)}\)

Using points A and A', the translation rule

\(\mathbf{(x,y) = A - A'}\)

This gives

\(\mathbf{(x,y) = (-1,-2) - (-4,-1)}\)

\(\mathbf{(x,y) = (-1+4,-2+1)}\)

\(\mathbf{(x,y) = (3,-1)}\)

This means that, the translation rule is:

\(\mathbf{(x,y) \to (x - 3,y+1)}\)

or

\(\mathbf{T_{-3,1}(x,y) }\)

If the interest is compounded continuously, an investment account with the same initial investment and the same APR will have the highest APY.

APY (Annual Percentage Yield) is the effective annual rate of return after compounding. The higher the APY, the more frequently the interest is compounded.

Compounding yields the highest APY because it effectively provides an infinite number of compounding periods. Compounding daily, monthly, or annually yields lower APYs than compounding continuously.

Step-by-step explanation:

There are a number of reasons why some students decide not to go to school. Some of them may be associated with family and psychological problems such as anxiety and depression, which should be investigated by trained professionals at the school if there is any suspicion of these symptoms.

There is also the possibility that students who have decided not to go to school have been victims of bullying and aggression at school, which causes fear of retaliation and psychological trauma that negatively impact the person's life.

It is important that schools provide psychological support and an active policy that combats bullying and is pro-integration of students and diversity.

The length s of the circular arc is 6.75π units

What is an angle?

Two lines intersect at a location, creating an angle. An "angle" is the term used to describe the width of the "opening" between these two rays. Angles are used in the design of buildings, roadways, and sports venues by engineers and architects.

A figure made by two intersecting lines or two rays extending from the same point is called an angle.The character ∠ is used to represent it. Angles are frequently expressed in degrees and radians, a unit of circularity or rotation. We encounter angles frequently in life.

Formula for the length s of the circular arc when angle θ is in radians:

s=r θ

=> s= 9(3π/4)  = (9*3*π)/4 = 6.75π units

Thus, the  length s of the circular arc is 6.75π units

Answer:

Step-by-step explanation:

Given the following :

Population in year 2000 (A) = 4.2 million

Expected population every 32 years = 2 *A

The growth rate per year =?

The population figure after 32 years = (2 * 4.2 million) = 8.4 million

Using the exponential growth formula :

P(t) = A × (1 + r)^t

(1 + r) = g = Total growth percent

A = Initial population

t = time

P(t) = 8.4 million

8,400,000 = 4,200,000 × g^32

g^32 = (8400000/4200000)

g^32 = 2

Taking the root of 32 on both sides

g = 1.02189714865

g = (1 + r)

1.02189714865 = 1 + r

r = 1.02189714865 - 1

r = 0.02189714865

The type of data collected by Parents Against Watching Television (PAWT) is quantitative data.

The type of data collected by PAWT is quantitative data, specifically interval data. This is because the data gathered, which is the number of hours per week that elementary school-aged children watch television, represents a measurable quantity.  

Data collected is numerical and the intervals between the numbers are equal (i.e. one hour of television is the same amount of time for every respondent). Quantitative data can be analyzed using numerical methods and is often used to make comparisons or draw conclusions. Additionally, mathematical operations such as calculating the mean or standard deviation can be applied to this type of data.

In this case, PAWT collected this data to better understand and address the concerns of parents regarding their children's television viewing habits.

Courtney rides for two hours on a bicycle, traveling 24 miles from her home. She has ridden for nine hours and is now 101 miles away. Courtney travels at a speed of 6 mph.

Let x represent the duration in hours and y the distance in miles.

Courtney travels 24 miles from her home after a two-hour ride.

She has traveled 101 miles after riding for nine hours.

rate is the slope

We divide the change in hours by the change in miles to find the rate.

\(Slope=\frac{y_{2} - y_{1} }{x_{2}-x_{1} } \\Slope=\frac{101-24}{9-2} \\Slope= \frac{77}{7} \\Slope=11\)

Therefore, Courtney's speed is 11 mph.

The speed of something or someone is shown to us. If you know how far and how long it took, you can find the average speed of an object.

The distance covered in a given amount of time would also double if one were to speed up. We need to know how far an object has traveled in order to determine its speed, and the slowest speeds are measured over the longest time periods.

Answer:   The probability that the no. is divisible by 4 is 0.225 .

Step-by-step explanation:

First three-digit number: a = 100

Last digit number: l = 996

Common difference: d = 4

Formula: l=a+(n-1)d

Substitute all values, we get

\(996=100+(n-1)4\\\\\Rightarrow 896=(n-1)4\\\\\Rightarrow n-1=\dfrac{896}{4}\\\\\Rightarrow n-1=224\\\\\Rightarrow n=225\)

i.e. there are 225 three digit numbers divisible by 4.

Total 3-digit numbers = 1000

The probability that the no. is divisible by 4 = \(\dfrac{225}{1000}=0.225\)

Hence, the probability that the no. is divisible by 4 is 0.225 .

The mean would be 83.583 and median would be 84.684.

To find out which value is mean and which value is a median we need to first understand the definitions of both the terms. Mean is defined as the sum of all the terms divided by the number of total number of terms present in the list. Median is defined as the middle term of the list when the terms is arranged in the ascending or descending order.

So, according to the values given, mean would be 83.583degrees . Since, we were to calculate the sum of all the values in the list and divide it by the total number of values, we would obtain an average. While when the list is arranged in ascending or descending order, the value in the middle comes out as 84.6degrees .

Therefore, in this case the mean would be 83.583 and median would be 84.684.

To answer your question, we first need to calculate the z-score formula. The z-score formula is:

z = (x - μ) / σ

Where:
x = the value we want to find the z-score for
μ = the mean of the distribution
σ = the standard deviation of the distribution

In this case, we are given that the distribution has a mean of 145.2 and a standard deviation of 16.8. We also know that we want to find the z-score for some performance values.

Let's say that the performance value we are interested in is 160. Using the z-score formula, we can calculate the z-score as:

z = (160 - 145.2) / 16.8
z = 0.88095

So the z-score for a performance value of 160 in this distribution is 0.88095.

It's worth noting that if the distribution is exactly normal, we can use a z-score table to find the percentage of values that fall below or above a certain z-score. However, if the distribution deviates from normality in any way, the z-score may not accurately represent the percentage of values in the distribution.
To calculate the z-score for a specific performance value in a distribution, you can use the following formula:

z-score = (value - mean) / standard deviation

Given the distribution has a mean of 145.2 and a standard deviation of 16.8, let's assume we have a specific performance value "X." You would then plug the numbers into the formula:

z-score = (X - 145.2) / 16.8

Replace "X" with the specific performance value you want to find the z-score for, and you'll have your answer.
