Answer:
Option A, The universe started at a central point, is the right answer.
Explanation:
Edwin Powell Hubble was an astronomer from America. He has played a very significant role in setting up the fields of extragalactic astronomy and observational cosmology. He has been credited with the founding of the Big Bang Theory. He made an observation about the Universe and explained that the Universe is continuously expanding. His finding supported that the Universe had a central starting point, almost all galaxies are moving away from us and that galaxies that are far from us move away faster.
Answer:
sec(4x) + C
Explanation:
original problem: ∫sec(4x)tan(x)dx
use integration by substitution (u-sub) by setting u = 4x
if u = 4x, then du/dx = 4 and du = 4dx (dx = du/4)
after substitution the integral is ∫sec(u)tan(u)(du/4)
move the 1/4 out of the integral by using the integral Constant rule to form 1/4∫sec(u)tan(u)du
the anti-derivative of sec(u)tan(u) is sec(u), memorize your trigonometric derivatives!!!!
after integration, we get sec(u)/4 + C , now plug u back into the equation
sec(4x) + C is the general solution

Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean. In graph form, normal distribution will appear as a bell curve.
