Many problems in math or science use quantities or numbers that are relatively easy to use or mentally picture such as 5, 10, 10,000, 6.5, etc. However, real-life situations in science or engineering often call for dealing with numbers that are either too large or too small such as the following: Handling and representing such …
In every society, there are fundamental principles that guide how things are done. These principles point us to expected ethical obligations. Theories that attempt to explain what we are obligated to do are known as ethical theories. Ethics help to clarify expected moral values with respect to right and wrong. Utilitarianism is an ethical theory …
Energy is the capacity to do work. It plays a vital role in modern life, driving many of our technological and industrial processes. Energy comes in different forms, including: Chemical energy Mechanical energy Heat energy Sound energy Electrical energy Radiant (light) energy Nuclear energy Tide energy Depending on the type of work you want to …
Hyperbolas can be hard to visualize and understand at first. To help you out, we will take a look at the definition of hyperbolas, where they come from, and check out real-life examples. First, consider a cone To better understand hyperbola, we should take a look at cones. You can get various shapes when you …
Direct variation is a mathematical concept that describes the relationship between two variables. The relationship can be expressed in the form of an equation whereby one variable is equal to a constant times another variable i.e. y =kx where y and x are variables and k is a constant. The value of y, therefore, changes …
We depend on electricity to carry out various tasks. Electric energy provides us with light to see in the dark. It powers our smartphones, televisions, and computers. It even powers our trains and vehicles. Put simply, electrical energy is the driving force of our economy and our modern lives. While electrical energy today can be …
We are always interacting with ratios often without realizing it. From comparing the heights of different people to comparing crowd sizes, ratios are an everyday experience. Ratios are a useful way of comparing two or more quantities of different things in order to better understand how they relate to each other. They can be expressed …
When two specific lines intersect at 90°, they are known as perpendicular lines. In other words, two lines are perpendicular to each other when a right angle is formed at their point of connection. A right-angle symbol shows the perpendicular lines in this right-angled triangle In geometric shapes, the right angle symbol denotes perpendicular …
When many people picture triangles, the images of triangles with at least two sides that are equal length come into mind. However, this isn’t always the case with triangles. Scalene triangles are triangles in which all three sides are of different lengths. The three angles within scalene triangles are also of different measures. Scalene triangles …
Angles are formed when two lines intersect at a common endpoint. The intersection point is known as the vertex of the angle. An obtuse angle is formed when the number of degrees measured at or near the vertex is between 90° and 180°. In a circle, an obtuse angle would be between a quarter of …
