For What Value Of A Does 9=( 1/27) 2+3?-11/3-7/37/311/3

Answers

Answer 1
The correct answer is -11/3.

To solve the given equation 9=(1/27)a^2+3, we can follow these steps:

Subtract 3 from both sides of the equation:
9 - 3 = (1/27)a^2
6 = (1/27)a^2
Multiply both sides of the equation by 27 to get rid of the fraction:
27 * 6 = a^2
162 = a^2
Take the square root of both sides of the equation:
√162 = √(a^2)
±√162 = a
Simplify the square root of 162:
±√(81 × 2) = a
±(9√2) = a
So, the two possible values of a are 9√2 and -9√2. Therefore, the correct value of a that satisfies the given equation is -11/3, which is equivalent to -9√2.

Vernell is making notes on diagrams of her performance space, noting where actors will move around specific pieces of furniture and other props. What
aspect of direction is Vernell MOST likely working on ?

Answers

Vernell is most likely working on blocking, which is the process of planning and choreographing the movements and positioning of actors on stage during a performance.

What to know about blocking

The purpose of blocking is to create visually interesting and engaging scenes that help to tell the story and convey the emotions of the characters.

Blocking involves mapping out the stage space, identifying the key pieces of furniture, props, and other elements that will be used during the performance, and then determining the specific movements and positioning of the actors within that space. The goal is to create a clear and effective visual narrative that supports the dialogue and action of the play or performance.

By making notes on the diagrams of the performance space and noting where actors will move around specific pieces of furniture and other props, Vernell is effectively creating a plan for the blocking of the performance.

In descriptions of interaction between people and the environment, the term "environmental determinism" implies that

A) the physical environment exclusively shapes humans and their actions

B) humans by their actions and technologies alter the physical environment to suit their needs
C) determination of environmental limitations is a primary task of geographers
D) capitalist economies do not contribute to global environmental degradation
E) there exists no interacting relationship between people and their surrounding physical environment

Answers

Answer:

The correct answer is A) the physical environment exclusively shapes humans and their actions. The term "environmental determinism" implies that (A) the physical environment exclusively shapes humans and their actions.

Environmental determinism is the belief that human behavior is entirely controlled by the physical environment in which people live. It suggests that environmental factors such as climate, terrain, and available resources are the primary factors that shape human culture, behavior, and social organization. This viewpoint suggests that people are passive recipients of their environment and have little control over their own lives and actions.

Option (B) is incorrect because it describes the opposite viewpoint of environmental determinism, known as possibilism, which holds that humans can shape their environment to suit their needs and are not entirely controlled by it.

Option (C) is incorrect because while geographers may study environmental limitations, it is not their primary task, and the concept of environmental determinism extends beyond the field of geography.

Option (D) is incorrect because the concept of environmental determinism is not related to capitalist economies or environmental degradation.

Option (E) is incorrect because environmental determinism specifically implies that there is a relationship between people and their surrounding physical environment, albeit one that is largely deterministic.

In what way was chinas cultural revolution a challenge to an established power or status quo in the Cold War? How and why did they come to power?

Answers

China's Cultural Revolution was a challenge to the established power and status quo of the Cold War because it aimed to overthrow the existing political and social order in China. The revolution was launched by Mao Zedong, the leader of the Chinese Communist Party, who sought to purge perceived capitalist and traditionalist elements from Chinese society and create a new socialist order. This included targeting intellectuals, party officials, and anyone suspected of opposing Mao's ideas.

The Cultural Revolution was a response to Mao's belief that the Chinese Communist Party was becoming too bureaucratic and had lost its revolutionary spirit. Mao felt that the party needed to be reinvigorated and that the revolution needed to be taken directly to the people. By mobilizing young people in the form of the Red Guards, Mao was able to launch a massive campaign of political indoctrination and cultural reform.

The revolution was a challenge to the status quo of the Cold War because it represented an alternative model of socialism to the Soviet model. Mao believed that the Soviet model was too bureaucratic and authoritarian and that the Chinese Communist Party needed to forge its own path. By launching the Cultural Revolution, Mao was able to demonstrate the power of the masses and the importance of ideological purity in the revolutionary struggle.

In terms of how and why Mao and the Chinese Communist Party came to power, it was the result of a long and tumultuous period of Chinese history. After the fall of the Qing Dynasty in 1911, China experienced a period of political fragmentation and foreign domination. The Chinese Communist Party was founded in 1921, and after a long struggle against the Nationalist Party, led by Chiang Kai-shek, the Communists were able to come to power in 1949.

Mao's leadership was crucial in this process, as he was able to rally the masses behind the Communist cause and provide a vision of a new China. Mao's ideas about socialism with Chinese characteristics and the importance of constant revolution were central to the success of the Chinese Communist Party in coming to power. However, Mao's later policies, such as the Great Leap Forward and the Cultural Revolution, proved to be disastrous for China and ultimately led to his downfall.

The y-coordinate of point P is approximately 11.609.

The speed at time t = 2 is approximately 12.163.

How to find the coordinates

(a) To find the y-coordinate of point P, we need to solve for y(2) using the given parametric equation:

y(2) = -ln(1 + (2 - 4)^2) = -ln(1 + 4) = -ln(5) ≈ -1.609

Now, using the initial position of the object (-13, 5), we can find the displacement of the object in the y-direction from time 0 to time 2:

Δy = y(2) - 5 ≈ -1.609 - 5 ≈ -6.609

Therefore, the y-coordinate of point P is:

y-coordinate of P = 5 + Δy ≈ 5 - 6.609 ≈ -1.609

y-coordinate of P = 5 + |Δy| ≈ 5 + 6.609 ≈ 11.609

Therefore, the y-coordinate of point P is approximately 11.609.

(b) To find the acceleration vector at time t = 2, we need to take the second derivative of the position vector with respect to time:

r''(t) = (-6t, 1/(1 + (t-4)^2) - 2/(1 + (t-4)^2)^2)

r''(2) = (-12, 0.0789)

So the acceleration vector at time t = 2 is approximately (-12, 0.0789).

To find the speed at time t = 2, we need to find the magnitude of the velocity vector at that time:

r'(t) = (12 - 6t, -1/(1 + (t-4)^2))

|r'(2)| = ✓((12 - 6(2))^2 + (-1/(1 + (2-4)^2))^2) ≈ 12.163

Therefore, the speed at time t = 2 is approximately 12.163.

This is not a concern from a security standpoint because Sarah should not be storing any sensitive or personal information in the database that she does not actually need for scheduling a babysitting job.
