Within the brain, impulses from a neuron's nucleus to its dendrites are conducted via a long fiber known as the Axon

Explanation:

An Axon is the long fiber found in the brain which helps the transfer of impulses from a neuron’s nucleus to it’s dendrites. Messages are always transferred in the form of electrical impulses through the neurons.  The Axon is responsible to carry through and fro of these impulses to various parts of the body.

This neuro transmission happens through the release of a chemical called the neuro transmitters. From the neurons the transmitter receives and passes the information to various parts of the body through signals that is caught and executed by the other parts.

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.
