Answer:

see attached

Explanation:

A differential equation solver says the exact solution is ...

y = 5/2 -14e^(-2x) +1/2e^(-4x)

The y-values computed by Euler's method will be ...

y = ∆x·y' = 0.1(5 - e^(-4x) -2y)

The attached table performs these computations and compares the result. The "difference" is the approximate value minus the exact value. (When the step size is decreased by a factor of 10, the difference over the same interval is decreased by about that same factor.)

The S3 encryption, Server-Side Encryption with Customer-Provided Keys (SSE-C), allows the company to leverage Amazon S3 for storing data with given constraints.

What do you mean by S3 encryption?
S3 encryption encrypts your data when it is written to disks in its data centers at the object level and decrypts it for you when you access it. There is no distinction between accessing encrypted or unencrypted items as long as you authenticate your request and you have access permissions.

S3 encryption encrypts an item before saving it to disk when you use server-side encryption; the object is then decrypted when you download the object. S3 encryption lets you safeguard the data you store in AWS S3 buckets online, which is crucial for sensitive data.
