For a particle with some position function y(t), we're given its velocity function v(t) = 1 - tan⁻¹(eᵗ ) and we're told that it starts with a position of y = -1 at the start.
(a) Acceleration is the rate of change of velocity, so to get the acceleration function a(t), you have to differentiate v(t) :
a(t) = d/dt v(t)
a(t) = d/dt [1 - tan⁻¹(eᵗ )]
a(t) = - d/dt [tan⁻¹(eᵗ )]
Apply the chain rule: take f(u) = tan⁻¹(u) and u(t) = eᵗ, so that
df/dt = df/du × du/dt
→ a(t) = - 1/(1 + u ²) × eᵗ = - eᵗ / (1 + e²ᵗ )
Then when t = 2, the acceleration is
a (2) = - e² / (1 + e⁴) ≈ -0.1329
(b) The acceleration of the particle at t = 2 is negative, so the particle's speed at this moment is decreasing. (Recall the first derivative test.)
(c) Note that at t = 0, the particle's velocity is v (0) = 1 - tan⁻¹(e⁰) = 1 - π/4 ≈ 0.2416 > 0. This means that the particle is moving upward at the start.
From part (a), we see that the acceleration is always negative, so the particle would be slowing down until it reaches zero velocity, after which point its velocity will become negative (meaning its speed would increase again as it starts to accelerate in the negative direction).
This means the particle's highest position on the y-axis occurs at the same time v(t) becomes 0, so you solve:
1 - tan⁻¹(eᵗ ) = 0
1 = tan⁻¹(eᵗ )
tan(1) = tan(tan⁻¹(eᵗ ))
tan(1) = eᵗ
ln(tan(1)) = ln(eᵗ )
ln(tan(1)) = t ≈ 0.443
(d) Use the fundamental theorem of calculus to find an expression for y(t) :
y(t) = y (0) + ∫₀ᵗ v(s) ds
(where s is just a dummy variable)
Then the particle's position at t = 2 is
y (2) = y (0) + ∫₀² v(s) ds
v(t) unfortunately does not have a nice antiderivative, so you'll have to use a calculator. (I hope this question is given in the calculator portion!) You would find
∫₀² v(s) ds ≈ -0.3607
so that
y (2) ≈ -1 + (-0.3607) ≈ -1.3607
The sign of the particle's velocity at this time tells you in which way the particle is moving. We have
v (2) = 1 - tan⁻¹(e²) ≈ -0.4363
which is negative, so the particle is moving away from the origin. This is consistent with the answer found in part (c):
• before t ≈ 0.443, the particle is moving upward toward the origin;
• at t ≈ 0.443, the particle reaches its highest point at y (2) ≈ -1.3607, then turns around and accelerates back downward and away from the origin

Why is it important to be aware of your self-concept and level of self-esteem when communicating with people? Why do people differ in their perceptions of people and events? How does the media affect your self-perception? What are some things you do to improve your self-perception?
The correct answers to these open questions are the following.
Here is the information that can help you write your posts.
Why is it important to be aware of your self-concept and level of self-esteem when communicating with people?
It is very important that you know yourself. It is the only way to develop the amount of trust needed to socialize without feeling fearful about what others could think about you. This means to trust yourself.
And the only way to know you better is through introspection. Yes, to really know how you think and how you feel.
You have to go inward, meditate, and respond to the following questions. What are my strengths, my weaknesses, and what can I do to overcome my weaknesses?
Why do people differ in their perceptions of people and events?
Because people have their own belief systems. And these belief systems determine their nature of reality. People see what they believe. In other words, people see what is only trained to see and that is what they accept as true.
For this reason, it is so important to respect other people's points of view and be tolerant. Nobody is right or wrong per se. Everybody has a piece of the truth and we have to be respectful if we want to have respect for our way of thinking.
How does the media affect your self-perception?
Mass media tries to impose criteria and belief systems, most of the time biased to consumerism. Most of the time, the media just want people to react not to think. And if the reaction is emotional, full of drama, much n¿better for them. That is why it is so important that you do not believe what appears on mass media. Have your sources, do research, have your own opiniom¿n,
What are some things you do to improve your self-perception?
As I mentioned above, I take time to meditate, to better know myself, develop more trust, be compassionate and tolerant. I focus on improving myself by studying and preparing, trying to do my best, and paying no attention to critics.
How did you get the 0.1 in the Zscore formula?
Answer:
Kindly check explanation
Explanation:
The Zscore formula given by the relation :
Zscore = (x - μ) / σ
Where ; μ = mean ; σ = standard deviation and x = score ; is used to obtain the standardized score for a given data using the mean and standard deviation of the data. The standardized score returns a value which is between 0 and 1. It is a very good method of scaling values in a data.
Once, the mean, standard deviation and score, x has been obtained, the Zscore formula converts x, into a standardized score. Whose probability can be forther looked up in the Z probability table.
Hence, if after applying the relation, a Zscore value of 0.1 is obtained, the 0.1 is the standardized score of x

120 men working 9 hours a day can construct a road in 40 days.how long would it take to construct the same road if 150 men work 6 hours a day on it?
This is a question from Ratio and Proportion based concept.
Given that,120 men working for 9 hours a day, construct a road in 40 days. We are required to calculate the number of days to construct the road if 150 people work for 6 hours.
Let's assume the number of days taken for constructing is 'x'.
So normally we take 2 ratios and obtain the unknown value by cross multiplication.
Applying the same approach we get:
[tex]\implies \frac{ 120\:men}{150\:men}=\frac{9\:hours}{6\:hours}=\frac{40\:days}{x\:days}[/tex]
Since the first two fractions are inversely related, we multiply the numerators and denominators respectively.
Hence we get:
[tex]\begin{gathered}\implies \dfrac{ 120\: men \times 9\: hours}{150\: men \times 6\: hours} = \dfrac{ 40\: days}{x\: days}\\\\\\\implies \dfrac{1080}{900} = \dfrac{40}{x}\\\\\\\sf{Cross~ multiplying ~these~ 2 ~fractions~ we~ get:}\\\\\\\implies 1080 \times x = 40 \times 900 \\\\\\\implies x = \dfrac{ 40 \times 900}{1080}\\\\\\\implies x = \dfrac{36000}{1080}\\\\\\\implies x = \boxed{ 33.33 \:\: days}\end{gathered}[/tex]
Hence it takes 33.33 days for 150 men to construct the road working for 6 hours each day.

checks if a number is between 0 and 101
Explanation:
Option D is the correct. The operator, &&, is known as the logical AND operator. It actually returns true if both operands are true or it will return false if otherwise.
So, it means that the operation is saying that if n=number is between 0 and 101, it returns true but if it is not, it returns false.
Actually, it is checking if a number is between 0 and 101.

Cassandra is giving a class presentation that involves a demonstration where she sprinkles some glitter into a small shallow dish of water and circularly swirls the water around with her finger. When she removes her finger, she asks her classmates to notice how the glitter moves around like a whirlpool, spiraling around the spot where she had removed your finger. What is Cassandra modeling with this demonstration?

how the arms in a galaxy interact
how the nuclear bulge of a galaxy moves

Explanation:
The Milky Way galaxy of which earth is a part of, is a spiral galaxy. This means that it appears as if it is a disk where the various components such as the stars, plants, gas and dust rotate around a central concentration of stars in the middle called the bulge.
This is what Cassandra was modelling. The glitter depicts the stars, gas and dust and the spot where she removed her finger is the bulge.
