Answer:

HAZMAT certificate

Explanation:

If you face an investigation where dangerous substances might be around, you may need to obtain a HAZMAT certificate.

Hazmat is the shortened form of the word "hazardous materials," which the United State Department of Transportation recognized as materials that could adversely affect people and also the environment. Hazmat certification is required to be obtained by workers who remove, handle, or transport hazardous materials. This comprises careers in transportation and shipping, firefighting and emergency rescue, construction and mining, as well as waste treatment and disposal. Workers who are also in manufacturing and warehouse storage may also come across hazardous substance or materials risks while on their jobs. Certification involves having the knowledge of the risks and safety measures for handling these materials.

Answer:

Explanation:

HAZMAT stands for Hazardous Materials. These are materials that could adversely affect people and the environment. Examples are synthetic organic chemicals, heavy metals and radioactive materials. People who work in certain industries such as construction and mining, firefighting, waste treatment and disposal e.t.c, are required to have this certificate.

The certification involves training workers in these industries in the use of, risk involved, and way of handling of these materials when they are encountered at work.

Radda [10]

Waterfall model and spiral model are used in software development life cycle or SDLC. Any software development process follows one of these models depending on the type of software and the requirements of the customer.

Waterfall model

This model is called as sequential model since it works in stages. The output of first stage becomes the input of the second stage.

The errors of the first stage can be rectified only when it is completed. This is time consuming and makes the process lengthy. Stage 1 is completed before stage 2 begins.

The six stages involved in waterfall model are Requirement Gathering and analysis, System Design, Implementation, Integration and Testing, Deployment of system, and Maintenance.

Spiral model

This model is implemented in iterations. It is also called evolutionary model.

Initially a prototype of the system is prepared. Then, it is followed by development of small parts of the system.

These smaller parts are then assembled to produce the final system.

The four stages which form the spiral model are Identification, Design, Development and Evaluation and Risk Analysis.

The differences between the two models are summarized below.

1. Waterfall model works in linear method. Spiral model follows evolutionary method.

2. Errors and risks are discovered/ rectified after the stage is over. Errors and risks are discovered/ rectified earlier.

3. Waterfall model is suitable for small projects. Spiral model is suitable for large projects.

4. Requirements identification and planning is the initial stage in the waterfall model. Requirements identification and planning is done when needed, in the spiral model.

5. Waterfall model allows little to no flexibility in the system. Spiral model allows flexibility in the system.

6. Low flexibility makes the waterfall model more risky. High flexibility makes the spiral model less risky.

7. Waterfall model, overall, takes less time since requirements are clear. Spiral model is implemented when the requirements of the system are not clear and become clear through prototypes.

An employee’s total weekly pay equals the hourly wage multiplied by the total number of regular hours plus any overtime pay. Ove

Feliz [49]

Answer:

C++ programming language is used to implement this program using Dev C++. You can use any C++ compiler to run this program. The code and its explanation is given below in explanation section.

Explanation:

#include<iostream>

using namespace std;

int main()

{

int totalWeeklyPay;//total weekly pay

int hourlyWage;// wages per hours

int totalRegularHour;// total regular hours worked

int totalOverTimeHour;// total over time hours worked

int weeklyTotalRegularPay;

int weeklyTotalOverTimePay;

cout<<"Enter Wage per hour: ";

cin>>hourlyWage;

if (hourlyWage<0)//if use enter negative value

{

cout<<"Please enter positive number number for wage per hour\n";

cout<<"Enter Wage per hour: ";

cin>>hourlyWage;

}

cout<<"Enter total regular hour: ";

cin>>totalRegularHour;

if (totalRegularHour<0)//if user enter negative value

{

cout<<"Please enter positive total number of regular hour\n";

cout<<"Enter total regular hour: ";

cin>>totalRegularHour;

}

cout<<"Enter total over time hour: ";

cin>>totalOverTimeHour;

if(totalOverTimeHour<0)//if user enter negative value

{

cout<<"Please enter positive total number of over time hour\n";

cout<<"Enter total over time hour: ";

cin>>totalOverTimeHour;

}

weeklyTotalRegularPay =hourlyWage*totalRegularHour;// total weekly regular hour pay

weeklyTotalOverTimePay=totalOverTimeHour*hourlyWage*1.5;// total weekly overtime pay

totalWeeklyPay=weeklyTotalRegularPay + weeklyTotalOverTimePay;//total weekly regular hour pay + // total weekly overtime pay

cout<<"Total Weekly Pay is: "<<totalWeeklyPay<<"$";//output

return 0;
