Richard throws a stone over a bridge into the river below. The stone's height, in meters above the water, x seconds after it is thrown is modeled
by h () = = -5 (x – 8) (x + 4).
a.) How many seconds after being thrown will the stone meet its maximum
height?
b.) What is the maximum height of the stone?

a.) In 1 second stone reach its maximum height

b.) 45 m

In my opinion, the correct answer is B. He uses logos to present rational arguments and then ethos to demonstrate that he lives by his principles. First, he writes about the unjust governments that people should disobey, as it is better to pursue what's right than what's lawful. Then, he sets his own example: by refusing to pay the taxes, he protested against slavery. He even had to bear consequences, so he spent some time in prison. This is a combination of logos and ethos - first, he elaborates his argument and logically supports it, and then goes on to prove that it is morally right to act upon it.

Explanation:

B is the He uses logos to present rational arguments and then ethos to demonstrate that he lives by his principles.
