Cosmic background radiation provides direct evidence for the origin of

Origin of the Universe

Explanation:

The Cosmic Microwave Background radiations are those electromagnetic radiations that are released right after the big bang explosion that resulted in the creation of the universe about 13.6 billion years back. These radiations were scattered in all the direction. They are not visible but their presence can be detected. These electromagnetic radiations helps in calculating the age and determining the composition of the universe. With the expansion of the universe, the energy as well as the matter that was initially present became less dense and were widely distributed in almost all the direction in space.

Thus, space is fully comprised of these radiations and it provides direct evidence for the origin of the universe that formed due to the big bang explosion.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
