WebApr 9, 2024 · If the sides of a square are unknown and we have the length of its diagonals then we can find the area of the square by using the below formula. Area = ½ × square of diagonal. There are also various other formulas for the determination of the area of squares which requires the knowledge of calculus. It will be studied in the higher classes. WebBefore jumping to the adjusted r-squared formula, we must understand what R2 is. In statistics, R2, also known as the coefficient of determination, is a tool that determines and assesses the variation in the dependent variable explained by an independent variable in a statistical model.

WebFinal velocity (v) squared equals initial velocity (u) squared plus two times acceleration (a) times displacement (s). v 2 = u 2 + 2 a s. Solving for v, final velocity (v) equals the square root of initial velocity (u) squared plus two times acceleration (a) times displacement (s). v = u 2 + 2 a s. Where: v = final velocity. u = initial velocity.
