How to Find the Perimeter of a Right Triangle
The perimeter of a right triangle is the sum of its three sides: P = a + b + c. If you only know the two legs, find the hypotenuse first with the Pythagorean theorem, c = √(a² + b²). For legs 3 and 4, the hypotenuse is 5, so the perimeter is 3 + […]
How to Determine Functions?
A relation is a function when each input has exactly one output. Repeated outputs are allowed; one input paired with different outputs is not. A function in mathematics is represented as a rule, which gives a unique output for each input \(x\). In this step-by-step guide, you will learn more information about defining functions and […]
