I have no idea, i just need points. Good luck
Answer: Online analytical processing
Explanation:
Online analytical processing(OLAP) is the method through which multi-dimension analytical queries can be resolved.User can attain selected query data as per their selection and then assess and analyze them from different view point.
- It helps in viewing and reporting , planning ,performing analytical calculation, collecting data in data cubes etc.
- Other options are incorrect because data adjacency, Ad hoc reporting ,data segregation and E-discovery are not the mechanism through which query and storage of data in data cubes take place.
- Thus, the correct option is online analytical processing
Classes cannot Initialize data members in the class definition.
B) Initialize data members in the class definition
<u>Explanation:</u>
Class is defined by end user data type where it can handle multiple data type and referred to other classes also. Class is also called as data structure object or object class.
Due to class methods total programming language coding style is changes. For example employee of an organization should hold his or her employee number, address detail, spouse details, salary details
Where in old style programming language we need to declare separate variable to hold the data types, where we can define employee as class which can hold employee number, address fields, and again define salary details as other class and add employee->employee number where key connect between to class which is called derived class.
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.
