Help me out on question 29 and 30 please

Solution Explorer is found in Microsoft Visual Studio.When we create a project in the c# or another programming language the solution explorer window is used. The Solution Explorer takes care of the projects and files.

Solution Explorer displays an overall view of the current project. In the Solution Explorer we can delete or add the file in the project. The Solution Explorer window displays the list that is contained in the current solution.

Option(a),Option(b) and Option(c) are the incorrect option for the Solution Explorer window.

So, Option(d) is the correct answer for the solution explorer.

Which type of app is the best choice when it is critical to be able to use the device's features but performance is not critical

lisov135 [29]

Answer:

Hybrid.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem.

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are seven (7) main stages in the creation of a software and these are; planning, analysis, design, development (coding), testing, implementation and execution, and maintenance.

Some of the models used in the software development life cycle (SDLC) are;

I. A waterfall model: it can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.

II. An incremental model: it refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.

III. A spiral model: it can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.

Basically, softwares are categorized into three (3) main categories based on the development platform and these are;

a. Web application.

b. Native application.

c. Hybrid application.

A hybrid application is a type of software application that is designed based on the combination of the elements of both web applications and native applications.

Typically, a hybrid application is a web application that is developed in a native application shell, using a standardized web programming language such as CSS, JavaScript, and HTML.

Generally, a hybrid application avails a programmer the opportunity to write a code for a mobile application once while accommodating or being compatible with multiple app platforms such as Android, Windows, iOS, etc.

Hence, a hybrid application is the best choice of an application when it's critical for the end users to be able to use the features associated with a device such as a mobile phone but performance isn't critical.

Define a method calcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a d

Rudik [331]

Answer:

import java.io.*;

public class Main {

public static void main(String[] args) throws IOException {

double baseLength = 0, baseWidth = 0, pyramidHeight = 0;

Object[] volume;

volume = calcPyramidVolume(baseLength, baseWidth, pyramidHeight);

}

public static Object[] calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight) {

double area = calcBaseArea(baseLength, baseWidth);

double volume = baseLength * baseWidth * pyramidHeight;

return new Object[]{volume, area};

}

public static double calcBaseArea(double length, double width) {

return length * width;

}

Explanation:

The problem is flawed because it is completely inefficient for one to create two separate methods to calculate the volume and the area when they can be done at once.

The second problem is that it was never specified whether to return something from the calcBaseArea method.

I assumed it required it, so it is not advisable to initiate the method as a double, but rather create it as an Object so that it can return two values: the volume and the area.
