Variablesallow us to manipulate data through the ___________.

Computers and Technology
1 answer:
gladu [14]3 years ago
8 0

Answer:

Reference

Explanation:

Variables provide reference to the stored data value.

For example:

int i = 0;

Here i is a variable of type int with an initial value of 0. i is a reference to this stored value 0. Now if I want to update the data, I can do so using this reference.

i = 1;

Now the reference is used to manipulate the stored data and change it to 1. In a similar manner all updates to the value can be done using the variable reference.

The equation of certain traveling waves is y(x.t) = 0.0450 sin(25.12x - 37.68t-0.523) where x and y are in
NNADVOKAT [17]

Answer:

A. 0.0450

B. 4

C. 0.25

D. 37.68

E. 6Hz

F. -0.523

G. 1.5m/s

H. vy = ∂y/∂t = 0.045(-37.68) cos (25.12x - 37.68t - 0.523)

I. -1.67m/s.

Explanation:

Given the equation:

y(x,t) = 0.0450 sin(25.12x - 37.68t-0.523)

Standard wave equation:

y(x, t)=Asin(kx−ωt+ϕ)

a.) Amplitude = 0.0450

b.) Wave number = 1/ λ

λ=2π/k

From the equation k = 25.12

Wavelength(λ ) = 2π/25.12 = 0.25

Wave number (1/0.25) = 4

c.) Wavelength(λ ) = 2π/25.12 = 0.25

d.) Angular frequency(ω)

ωt = 37.68t

ω = 37.68

E.) Frequency (f)

ω = 2πf

f = ω/2π

f = 37.68/6.28

f = 6Hz

f.) Phase angle(ϕ) = -0.523

g.) Wave propagation speed :

ω/k=37.68/25.12=1.5m/s

h.) vy = ∂y/∂t = 0.045(-37.68) cos (25.12x - 37.68t - 0.523)

(i) vy(3.5m, 21s) = 0.045(-37.68) cos (25.12*3.5-37.68*21-0.523) = -1.67m/s.

What can a human till do better and fater than any Machine Learning (ML) olution?
Gemiola [76]

Judge the quality of any given data can a human till do better and fater than any Machine Learning (ML).

<h3>What is Machine Learning (ML)?</h3>
  • Switch between fields of expertise. a thorough understanding of the facts' meaning. Check the veracity of any information that is provided.
  • According to some scientists, AI will replace jobs with a single output. A mental task may also be mechanized in the future if it can be finished by a person in less than a second.
  • Expressing empathy, making others feel good, taking care of others, expressing feelings and vulnerability in a sympathetic way, and making people laugh are all examples of being creative and artistic for the purpose of being creative. The personal touch is important in most occupations and, in certain cases, it completes the task entirely.
  • Machines can perform as well as or better than humans in some tasks, despite their slower rate of development.
