(1 Point)
sin (0) = -2/2 270º < 0 < 360° how to solve
Answer:
[tex]\cos(2\theta) = 0[/tex]
Explanation:
Given
[tex]\sin(\theta) = -\frac{\sqrt 2}{2}[/tex]
[tex]270^o < \theta < 360^o[/tex]
Required
[tex]\cos(2\theta)[/tex]
Recall that:
[tex]\sin^2(\theta) + \cos^2(\theta) =1[/tex]
Substitute: [tex]\sin(\theta) = -\frac{\sqrt 2}{2}[/tex]
[tex](-\frac{\sqrt 2}{2})^2 + \cos^2(\theta) =1[/tex]
[tex]\frac{1}{2} + \cos^2(\theta) =1[/tex]
Collect like terms
[tex]\cos^2(\theta) =1-\frac{1}{2}[/tex]
[tex]\cos^2(\theta) =\frac{1}{2}[/tex]
[tex]\cos(2\theta)[/tex] is calculated as:
[tex]\cos(2\theta) = \cos^2(\theta) - \sin^2(\theta)[/tex]
So, we have:
[tex]\cos(2\theta) = \frac{1}{2} - (-\frac{\sqrt 2}{2})^2[/tex]
[tex]\cos(2\theta) = \frac{1}{2} - \frac{2}{4}[/tex]
[tex]\cos(2\theta) = \frac{1}{2} - \frac{1}{2}[/tex]
[tex]\cos(2\theta) = 0[/tex]
How have Human Beings Corrupted their Environment?
(5) I turned on my back and floated, looking up at the sky, nothing
around me but cool, clear Pacific, nothing in my eyes but long blue
space. It was as close as I ever got to cleanliness and freedom, as far as I
ever got from all the people. They had jerrybuilt the beaches from San Diego
to the Golden Gate, bulldozed superhighways through the
(10) mountains, cut down a thousand years of redwood growth, and built
an urban wilderness in the desert. They couldn't touch the ocean. They
poured their sewage into it, but it couldn't be tainted.
There was nothing wrong with Southern California that a rise in the
ocean level wouldn't cure. The sky was flat and empty, and the water was
(15) chilling me. I swam to the kelp-bed and plunged down through it. It
was cold and clammy like the bowels of fear. I came up gasping and
sprinted to shore with a barracuda terror nipping at my heels.
I was still chilly a half hour later, crossing the pass to Nopal Valley.
Even at its summit, the highway was wide and new, rebuilt with somebody's
(20) money. I could smell the source of the money when I slid down into the
valley on the other side. It stank like rotten eggs.
The oil wells from which the sulphur gas rose crowded the slopes on both
sides of the town. I could see them from the highway as I drove in: the
latticed triangles of the derricks where trees had grown, the oil-pumps
nodding and clanking where cattle had grazed. Since 'thirty-nine or 'forty, when
I had seen it last, the town had grown enormously, like a tumor.
25) What are the dominant images in lines 10-12?
A. Light and dark

Describe history. What is history? How is history
constructed? How does this apply to Texas history?
Answer:
History can describe as the the whole series of past events connected with someone or something.
History is the study of change over time, and it covers all aspects of human society.
History is made up of persons who lived in a certain time in the past.
The recorded history of Texas begins with the arrival of the first Spanish conquistadors in the region of North America now known as Texas in 1519, who found the region occupied by numerous Native American tribes. The name Texas derives from táyshaʼ, a word in the Caddoan language of the Hasinai, which means "friends" or "allies."[1][2][3][4] Native Americans' ancestors had been in what is now Texas, more than 10,000 years ago as evidenced by the discovery of the remains of prehistoric Leanderthal Lady.
Answer:
History is the past of many occuring events.
History is constructed using a timeline of events that had happened.
This applies to Texas history because there are events that took place and are related to Texas in the past.

Why did many state governors in the South oppose the Confederate government during the Civil War? They disagreed with its war plan. They were tired of fighting the war. They resented Confederate taxes. They wanted it to rejoin the Union.
no scam please
Answer: They resented Confederate taxes.
Explanation:
One of the reasons the Southern sates left was to be more independent as they did not appreciate the powers of a strong central government. The Confederate government therefore, was not to be very strong and capable of overriding the powers of state government.
This changed as the war went on however because a strong central government was needed to coordinate efforts. The President, Jefferson Davis, introduced taxes amongst other things and this did not sit well with Southern governors who felt that their authority was being stripped away.
Answer:
C) They resented Confederate taxes.
