Solve x2 – 4x 1 = 0. Mc002-1. Jpg mc002-2. Jpg mc002-3. Jpg mc002-4. Jpg.
Answer:
Solution
=2±√3
Explanation:
The solution of the given equation x² - 4x + 1 = 0 is;
x = 2 ± √3
We are given;
x² - 4x + 1 = 0
Using quadratic formula we have;
x = [-b ± √b² - 4ac]/2a
where;
a = 1
b = -4
c = 1
Thus;
x = [-(-4) ± √((-4)² - 4(1 * 1)]/2(1)
x = (4 ± √(16 - 4))/2
x = (4 ± √12)/2
x = (4 ± 2√3)/2
x = 2 ± √3

Answer:
aaaaaaaaaaaaaaaaaaaaaaaaaa it a
Explanation:
Albert Einstein’s Theory of Relativity is the scientific innovation occurred that affected the art that was produced during this period. The correct option is A.
What is Albert Einstein’s Theory of Relativity?Albert Einstein's Theory of Relativity is a set of two interrelated theories that fundamentally changed our understanding of space, time, and gravity. The first theory, called Special Relativity, was published by Einstein in 1905 and dealt with the physics of objects moving at high speeds. The second theory, called General Relativity, was published in 1915 and extended the ideas of Special Relativity to include gravity.
Special Relativity postulates that the laws of physics are the same for all observers who are moving at a constant speed relative to one another. This means that there is no single "absolute" time or space, but rather that these concepts are relative to the observer's frame of reference. The theory also introduced the concept of time dilation, which means that time appears to slow down for objects moving at high speeds relative to a stationary observer.
General Relativity, on the other hand, describes gravity as the curvature of spacetime caused by the presence of matter and energy. In this theory, massive objects warp the fabric of spacetime, causing other objects to move along curved paths. This explains why objects orbit around each other, as well as the bending of light around massive objects.
Einstein's Theory of Relativity has had a profound impact on modern physics and our understanding of the universe. It has led to the development of new technologies such as GPS and has provided a framework for further research into the nature of the universe, including the study of black holes, the Big Bang, and the search for a unified theory of physics.
Here in the Question,
This scientific innovation, introduced in the early 20th century, revolutionized the way scientists and artists understood space, time, and the nature of reality. The concept of relativity, which challenged the traditional Newtonian worldview, had a significant impact on modern art movements such as Cubism and Futurism, which sought to depict multiple perspectives and the dynamic nature of reality. The theory also had a profound influence on the development of abstract art, which aimed to represent the invisible forces and structures that underlie the visible world.
Therefore, The best answer is A. Albert Einstein’s Theory of Relativity.

Julissa is printing out copies for a work training. It takes 4 minutes to print a color copy, and it takes 2 minutes to print a grayscale copy. She needs to print no fewer than 8 copies within 25 minutes. Which system of inequalities represents the number of color copies, x, and grayscale copies, y, that Julissa can print to meet her goal?.
The system of inequalities for Julissa can be given as 4x + 2y ≤ 25
and x + y ≥ 8.
What is a system of inequalities?
The system of inequalities is given with the use of the more than inequalities for the correspondence to one variable.
In the given system, the inequalities lies with the grayscale copies, and color copies with the time limit of 25 minutes and minimum number of 8 copies.
Let the number of color copies = x
The time taken to print each color copy = 4 minutes
Thus, the time taken to print x color copies = 4x
Let the number of gray scale copies = y
The time taken to print each gray scale copy = 2 minutes
Thus, the time taken to print y gray scale copy = 2y
Total copies printed = x + y
Maximum time taken to print x color copies and y grayscale copies = 25 minutes
So,
4x + 2y ≤ 25
and x + y ≥ 8
