If 2+7z=-z -4, what is the value of z?

Answers

Answer 1

Answer:

z = -0.75

Explanation:

First is to combine all z variables (to do this, let's add +z to both sides):

2+8z=-4

Now, let's put all of the integers on the right side of the equation:

8z=-6

Divide by 8 on both sides:

[tex]z=-\frac{6}{8}[/tex]

Simplify:

[tex]z=-\frac{3}{4}[/tex]

Also:

z = -0.75

What was the pentagon papers case?

According to the Pentagon Papers, American soldiers were still being sent to fight in a lost war by Eisenhower, Kennedy, and Johnson. Presidents, generals, and other government representatives had lied to the public to defend these actions. A breach of the Geneva Convention had occurred

The Supreme Court ruled that the First Amendment protects the right to publish all statements. According to the Court, a public official must demonstrate genuine malice, which is "knowing that it was untrue or reckless contempt for the truth," in order to establish libel.

In an effort to stop the Times from printing more of the records, the government swiftly filed a court injunction. They claimed that doing so would jeopardize national security.

Which of the following played sound recorded on wax cylinders?
A.television
B.radio
C.printing press
D.phonograph
Please help me it’s for music

Answers

the answer is D. phonograph

Phonograph played sound recorded on wax cylinders. Option (D) is correct for the question.

What do you mean by Radio?

Radio is a form of sound transmission over radio waves that often involves the distribution of music, news, and other programming from a single broadcast station to a large audience of listeners with radio receivers.

When the cylinder is turned, the stylus pushes into the wax and creates a groove. The stylus vibrates along with the sound and moves very slightly up and down as well, recording the sound in the groove on the wax.

Thomas Edison came up with the idea for the phonograph on July 18, 1877, when he was testing waxed paper. The recordings were made on the outside of a strip of tinfoil that had been wound around a rotating metal cylinder in the early production versions.

Therefore,  Option (D) is correct. Phonograph played sound recorded on wax cylinders.

A galvanometer is an instrument for measuring a small electrical current or a function of the current by deflection of a moving coil.

What are gator clips?

It is a spring-loaded clip that has jaws resembling an alligator's and is used for making temporary electrical connections.

What determines the direction of the reading on a galvanometer?

The deflection of the galvanometer needle indicates the presence of current in the coil. The direction of deflection of the needle gives us the direction of the flow of current.

Thus, the current is decreased when electrodes are switched by making the galvanometer reading zero.
