What are the amplitude, period, and phase shift of the given function?
Ft) = -4 sin (7t + 3)

Answers

Answer 1

Answer:

Amplitude: 4

Period: 0.898 seconds.

Phase shift: 6.142 radians.

Explanation:

A sinusoidal function is defined by the following model:

[tex]F(t) = A\cdot \sin (\omega\cdot t + \phi)[/tex] (1)

Where:

[tex]A[/tex] - Amplitude.

[tex]\omega[/tex] - Angular frequency, measured in radians per second.

[tex]\phi[/tex] - Phase shift, measured in radians.

We need to transform the given function into this form by trigonometric means. The following trigonometric identity is used:

[tex]-\sin \theta = \sin (\theta + \pi)[/tex] (2)

Then,

[tex]F(t) = -4\cdot \sin (7\cdot t + 3)[/tex]

[tex]F(t) = 4\cdot \sin (7\cdot t +3+\pi)[/tex]

Then, the following information is found:

[tex]A = 4[/tex], [tex]\omega = 7\,\frac{rad}{s}[/tex], [tex]\phi = (3+\pi)\,rad[/tex]

The period of the given function ([tex]T[/tex]), measured in seconds, is determined by the following formula:

[tex]T = \frac{2\pi}{\omega}[/tex] (3)

[tex]T = \frac{2\pi}{7}[/tex]

[tex]T \approx 0.898\,s[/tex]

Then, the following information is found:

Amplitude: 4

Period: 0.898 seconds.

Phase shift: 6.142 radians.

It provides steps on how to ensure that all people have equal rights . It compares the rights that people in different nations have access to compares rights that are and are not protected by the United Nations

Answers

Answer:

It provides steps on how to ensure that all people have equal rights

Because of this very logical and well-defined structure, the declaration is easily accepted and defended by the population.

Explanation:

The higher rate of accidents associated with drivers who text while behind the wheel is clearly a negative consequence of doing so. As such, it belongs in the part of the presentation that exposes the dangers of texting while driving.

In the presentation of the solution, Ben should include AI developments that better voice texting.

Positive effects of the proposed solution should be reserved for the last few slides before the conclusion.

When the first shot of the Civil War was fired at four thirty in the morning on April 12, 1861, many believed that it would be a short conflict. Even though Fort Sumter had to endure thirty-four hours of Confederate bombardment before the Union surrendered it, the Union enjoyed a number of significant advantages over the Confederacy. Yet, by the time Robert E. Lee surrendered to Ulysses Grant at Appomattox, Virginia, some four years later, about 620,000 soldiers had died on the battlefields, more than American battle deaths in all other wars from the Revolution through the Vietnam War.


How does this paragraph from The Dark Game best support the central idea that the Civil War was a long war?

a
It shares the detail that the war lasted four years.
b
It gives an example of a battle that lasted almost two days.
c
It states what people believed about the war at the time.
d
It tells how many soldiers actually died in the war.

According to the article, what has contributed to the increase in people attempting to summit Denali over the past century? * 1 point A. Rising temperatures B. Improvements in climbing gear C. E. Coli D. Glacier movement

Answers

Answer:

B. Improvements in climbing gear

Explanation:

Denali is the highest mountain in the USA and is one of the most difficult to climb. The difficulty of climbing is mainly due to the inhospitable climate, composed of very low temperatures that hinder the survival of climbers. In addition, the mountain has numerous very steep vertical climbs that make climbing extremely difficult. However, the number of people who try to climb this mountain is much greater than the number of people who tried to do it in the last century. This is probably a result of the advancement of climbing techniques and equipment, which has become increasingly safe and efficient in helping difficult mountain climbs like Denali.
