Periodic behavior is common in nature. For example, animal populations, sound waves, and the tides all exhibit periodic behavior. The ocean flows from high tide to low tide, then back over and over again. This motion can be modeled by trigonometric functions. Follow the directions below to explore one such example.
Throughout the day the depth of water at the end of a pier varies with the tides. High tide occurs at 4:00 a.m. with a depth of 6 meters. Low tide occurs at 10:00 a.m. with a depth of 2 meters.
1. Model the problem by using the given trigonometric equation to show the depth (y) of the water x hours after midnight, showing all your work. y = A cos(Bx + C) + D
Start by sketching a graph of the situation – sketch 2 cycles. (Pick appropriate intervals for the x- and y-axes and make the horizontal axis in time, not radians. Hint: What time should x = 0 be?)








Use the above graph and any extra work needed to determine the amplitude, period, and horizontal shift, and vertical shift to model the equation. Period and phase shift must be in radians.
Amplitude = _________
Period (in time) = ________ convert period to radians: ___________________________
Horizontal shift (in time) = ________ convert phase shift to radians: _______________________
(To find the phase shift use: -CB=x, where x is the horizontal shift in time.)
Vertical shift = _________
Equation: __________________________________________________________
2. A large boat coming in at noon needs at least 4 meters of water to dock at the end of the pier. Will the boat be able to safely dock? Solve the problem by using the equation to find the exact depth of the water at noon. Explain your reasoning.

Show work below: (Hint: how much time after x=0 is noon?)












Will the boat be able to dock safely? _______________________________________________________

Explain your answer/reasoning: ___________________________________________________________
_____________________________________________________________________________________
_____________________________________________________________________________________
3. Color a fun dock/pier ocean-scape on your graph.

In Night by Elie Wiesel Dehumanization is the process by which Nazis gradually reduced the Jews to little more than “things” whi
melisa1 [442]

Answer:

Really good book, by the way... Please mark Brainliest.. But, here's your answer

1. Pushed on board a train with many people without food and with limited water.

2. Thrown food by the Nazis so that they would fight over the bread.

3. They were separated one by one based on their physical attributes and their gender.

Being shoved into a train with many other people without food for a long journey can feel very dehumanizing, as it is cruel to do to even an animal, yet it was done to all of them. It had a big impact on Ellie, as he even states that he still vividly remembers the people in the train, curled up, people bullying others for food, and starving them. Even as young as he was when he experienced it, he still remembers the smell of the burning bodies at the concentration camp and the pain people were going through.

When the Nazis were throwing bread at the Jews on board the train, it impacted Ellie as he saw people being killed, just so they could steal the bread from them. Even while this was happening, the Nazis were laughing at them and throwing bread at them like animals at a zoo.

Lastly, being separated from other people can be dehumanizing, when a strong man is separated into a "better" category, just because he can do more than you. All women and children who were incapable of doing as much as the Nazis wanted were sent to showers to be gassed to death; they were ruthlessly killed and everybody in the camp knew it. That was one item that Ellie remembered very well even being the age that he was.

gregori [183]

The answer is : he presents projected investment that will benefit the country.

Explanation:

With this statement Kennedy, states that space and related industries have potential for growth , so it is wise to make an investment in this field, as it will help generate income and job opportunities to people, thus making it beneficial for the country.

So, he projects the investment for the next 5 years, which talks about how the National Aeronautics and space Administration expects to double the number of scientists and engineers.

How much money will be given out as salaries to these people, and how much money will be allocated to new plant and laboratories facilities.

This way it will help these industries to come up and contribute to the country's economy in the long run.

PLEASE ANSWERR<br> How can you tell if a speech you've written is clear and concise?
avanturin [10]
I would say that how you can tell if your speech is written clear and concise is by making sure your words aren’t misspelled, you use your grammar properly, you don’t go off topic, getting to the point of what you are taking about in a short manner and then going on to explain, make sure your audience can understand the point you are making easily, and chose wise words, get rid “that” and “there is.” Hope this helps..
