1.Which of the following correctly describes the Big Bang theory?

The majority of the universe was formed in a giant explosion that threw material out in all directions. Only a few galaxies already existed at the time of this explosion.

The large explosions in the universe that are constantly happening are what allows it to keep expanding. Without these "Big Bangs," the universe would all crunch together.

When a large star grows old and runs out of fuel, it is thought that the result is a very large explosion. This explosion is called the "Big Bang."

What is the approximate value of 0, if cos 0 = 7/9

Answers

The value of 0 (zero) is always 0, regardless of the value of the trigonometric function cos(0). In this case, if cos(0) is equal to 7/9, it simply means that the cosine of the angle 0 (in radians or degrees) is 7/9, but the value of the angle itself (0) remains zero.

In trigonometry, the cosine (cos) of an angle measures the ratio of the length of the adjacent side to the hypotenuse in a right triangle. When we have cos(0) = 7/9, it means that in a right triangle with an angle of 0 degrees (or 0 radians), the length of the adjacent side is 7, and the length of the hypotenuse is 9.

Using the Pythagorean theorem, we can find the length of the opposite side:

\[a^2 + b^2 = c^2\]\[7^2 + b^2 = 9^2\]\[49 + b^2 = 81\]\[b^2 = 81 - 49\]\[b^2 = 32\]

Taking the square root of both sides:

b = √32 = 4√2

So, in this triangle, the length of the opposite side is 4√2, and the cosine of the angle 0 is indeed 7/9.
