Whenever you have a constant rate change, this gives a linear relationship. Essentially, this is a relationship where one variable changes at a constant rate in relation to the other. A linear relationship will always produce a straight line when graphed. Since it has two variables, it has two dimensions which are represented by the …
Decimal numbers are numbers with a point placed in them to separate some of their digits. For example, the decimal number 98.04 has a point between 8 and 0. Decimals are just a different way of expressing fractions. For example, you can express 1/4 as 0.25. This is done by dividing your fraction completely so that you …
Liters, cubic feet, gallons are just a few units of volume that we encounter every day. Volume is probably one of the most common and important measurements we use in our daily lives. It is a measurement of the space occupied by an object or substance such as gases or liquids. It can also be …
A rate is a way of comparing two things. It’s a ratio that relates two rates so that you can know how much of one goes with the other. Rates are commonly used in many situations such as in a grocery or when exchanging currency. Unit rates, also called single-unit rates, are a special type …
If you have ever dealt with triangles, then you have dealt with trigonometry. This is an area of math that studies the triangle including the angles and length relationships that define it. From plotting stars to voyaging the seas, trigonometry is all around us. The Right-angled triangle Applications in trigonometry are done with right-angled triangles. …
Triangles, squares, and circles are some of the basic shapes we encounter in our day-to-day images. They have length and width and completely enclose a space. They are referred to as two-dimensional (2D) shapes because they only have two dimensions (measurable features) i.e. length and width. Three-dimensional shapes are those that have three measurable features …
Any solid object or 3D figure has a surface area. This is the total sum that is found by adding up the area of all its sides. For example, a cylinder has 3 sides: To get the surface area, you must get the separate areas of each side and add them all up. You can …
An inverse variation is a kind of relationship where one value increases while the other one decreases. For example, if one quantity increases while the other decreases, the quantities can have an inverse relationship. Inverse variation is the opposite of direct variation, where there is a linear relationship between two variables. An inverse variation relationship …
Whenever we have items or events following each other in a given order, we call this a sequence. Arithmetic sequences are a special type of sequence that deals with numbers. Also known as arithmetic progression, it consists of numbers ordered with each term having a common difference d with the successive term. The sequence has …
Increase is an exciting word to most people. But compound interest is a special kind of increase that has been described as magic. Compound interest works by adding earned interest to the original amount (principal) so that both the principal and interest earn interest. To achieve this, each time interest is earned it should be …
