x(t) = 2.31 + 4.90t² – 0.10t⁶

If we are going to differentiate the equation in terms of x, we get the value for velocity.

dx/dt = 9.8t – 0.6t⁵

Calculate for the value of t when dx/dt = 0.

dx/dt = 0 = (9.8 – 0.6t⁴)(t)

The values of t from the equation is approximately equal to 0 and 2.

If we substitute these values to the equation for displacement,

(0) , x = 2.31 + 4.90(0²) – 0.1(0⁶) = 2.31

(2) , x = 2.31 + 4.90(2²) – 0.1(2⁶) = 15.51

Thus, the positions at the instants where velocity is zero are 2.31 and 15.51 meters.

Written language often requires a more fluent level of comunication, which can prevent people from expressing their attitudes and emotions.

Spoken language, however, allows the speakers to add their own touch to the conversation, like facial expressions and hand movements.

Let’s assume that this question is referring to every digital calendar ever made. As in, even those made on devices without internet connectivity or any other fancy features that we utilize with many digital calendars today.

If a planning device that came with a digital calendar didn’t have internet connectivity, it wouldn’t be able to be connected to the cloud. Back when these devices were around, it wasn’t even plausible to store things like calendar events and contacts in what we know as the “cloud”. Also, these devices probably had to be hardwired to a computer and new software had to be downloaded to them, so the updates weren’t automatic. Archaic, right?

Also, consider the fact that even reputable websites/companies such as Google with Google Calendars or Apple with iCalendar will never go without their malfunctions or threats. Sometimes, these websites can be hacked and the data that they contain can be compromised, especially if they’re stored on the cloud. Also, even though it’s not realistic, Google or Apple could one day decide to completely get rid of their calendar programs altogether. So, this means that digital calendars are definitely able to be destroyed or lost.

That just leaves “They can be used anywhere”. This is true, even with those archaic devices specifically used for scheduling events and such. Nowadays, you have your phone and possibly a laptop on you at all times, which will likely have a calendar on it as a stock application. So, I think this is your answer.

Hope this helped you out! 🙂

The correct answer is **A) the effects of unchecked immigration.**

*The political that this cartoon illustrates is the effects of unchecked immigration.
*

The cartoon describes a situation of immigrants. So, it illustrates the effects of unchecked immigration with so many people entering the United States with no order at all. The situation shows the risk of a lack of immigration policy could have on the country and the possible consequnences of such a few restrictions to enter the U.S.

The sign that says *“Baggage the only Requisite*”, showed how easy was for people to enter the United States. And the pice of paper on the floor, besides Uncle Sam, with the names of *“Mafia in New Orleans”, “Anarchist in Chicago”, and “Socialist in New York”, *is an example of the strong journalism critic of that time.

**Answer:**

a) The time the police officer required to reach the motorist was 15 s.

b) The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) The total distance traveled by the officer was 225 m.

**Explanation:**

The equations for the position and velocity of an object moving in a straight line are as follows:

x = x0 + v0 · t + 1/2 · a · t²

v = v0 + a · t

Where:

x = position at time t

x0 = initial position

v0 = initial velocity

t = time

a = acceleration

v = velocity at time t

a)When the officer reaches the motorist, the position of the motorist is the same as the position of the officer:

x motorist = x officer

Using the equation for the position:

x motirist = x0 + v · t (since a = 0).

x officer = x0 + v0 · t + 1/2 · a · t²

Let´s place our frame of reference at the point where the officer starts following the motorist so that x0 = 0 for both:

x motorist = x officer

x0 + v · t = x0 + v0 · t + 1/2 · a · t² (the officer starts form rest, then, v0 = 0)

v · t = 1/2 · a · t²

Solving for t:

2 v/a = t

t = 2 · 15.0 m/s/ 2.00 m/s² = 15 s

The time the police officer required to reach the motorist was 15 s.

b) Now, we can calculate the speed of the officer using the time calculated in a) and the equation for velocity:

v = v0 + a · t

v = 0 m/s + 2.00 m/s² · 15 s

v = 30 m/s

The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) Using the equation for the position, we can find the traveled distance in 15 s:

x = x0 + v0 · t + 1/2 · a · t²

x = 1/2 · 2.00 m/s² · (15s)² = 225 m

March 4, 1933, was perhaps the Great Depression’s darkest hour. The stock market had plunged 85% from its high in 1929, and nearly one-fourth of the workforce was unemployed. In the cities, jobless men were lining up for soup and bread. In rural areas, farmers whose land was being foreclosed were talking openly of revolution. The crowd that gathered in front of the Capitol that day to watch Franklin D. Roosevelt’s Inauguration had all but given up on America. They were, a reporter observed, “as silent as a group of mourners around a grave.”

Roosevelt’s Inaugural Address was a pitch-perfect combination of optimism (“The only thing we have to fear is fear itself”), consolation (the nation’s problems “concern, thank God, only material things”) and resolve (“This nation asks for action, and action now”). The speech won rave reviews. Even the rock-ribbed Republican Chicago Tribune lauded its “dominant note of courageous confidence.” F.D.R. had buoyed the spirits of the American people — and nearly 500,000 of them wrote to him at the White House in the following week to tell him so.

Hours after the Inauguration, Roosevelt made history in a more behind-the-scenes way. He gathered his Cabinet in his White House office and had Justice Benjamin Cardozo swear them in as a group, the first time that had ever been done. F.D.R. joked that he was doing it so they could “receive an extra day’s pay,” but the real reason was that he wanted his team to get to work immediately.

And that team came through brilliantly. In the next 100 days — O.K., 105, but who’s counting? — his Administration shepherded 15 major bills through Congress. It was the most intense period of lawmaking ever undertaken by Congress — a “presidential barrage of ideas and programs,” historian Arthur Schlesinger Jr. observed, “unlike anything known to American history.”
