Flodding on rivers is caused by human activity rather than natural events true or false

ValentinkaMS [17]

Answer:

True

Explanation:

While I believe it's a compendium of the both(both true and false), I when asked to pick just one, I would go with yes. They're are lots of things we humans do on a general note that causes flooding. Although, heavy rainfall can also cause flooding and that's not as a result of human activity, but directly. But then, activities like not maintaining a dam, or erecting a structurally failed dam can cause flood to occur at any point in time, without warning even. Another way is when due to our activities, we block the rivers, this can also lead to flooding exactly like the case of heavy rainfall does. Lack of good drainage facilities, drainage wouldn't create itself, we as humans do. When we don't were essentially creating an excuse for an eventual happening of flood.

Succinctly put, human activities also cause floods, as much as natural events causes flood.

Given that a function receives three parameters a, b, c, of type double , write some code, to be included as part of the functio

hoa [83]

Answer:

public static void quad(double a, double b, double c) {

double D = (Math.pow(b, 2)) - (4 * a * c);

if (D<0){

System.out.println("no real solutions");

}

Explanation:

The code snippet above implements the function in Java programming language

As required by the question, the line double D = (Math.pow(b, 2)) - (4 * a * c); evaluates b squared" - 4ac and assignes the value to the variable D

An if statement is used to test if D is less than 0, if this is true the message no real solutions is printed

Course has Section

Test is conducted for Course

Test is conducted in Section

Test is conducted in Room

Attributes of each entities are as follows:-

Course (CourseID, Name, Department)

Section (SectionID, Enrollment)

Room (RoomNumber, Capacity, Building)

Test (Time)

Section is a week entity as, there may be same sections for different courses, therefore section uses the primary key of course entity as foreign key.

Also entity Test is dependent upon the entities Room,Section and Course, therefore primary keys of these entities will be used as foreign key in the Test entity.
