The formula to find the square root is: y = √a Since, y.y = y2= a; where ‘a’ is the square of a number ‘y’. Properties of Square root Some of the important properties of the square root are as follows: If a number is a perfect square number, then there exists a perfect...
To show that √ n is an irrational number unless n is a perfect square, explain how the assumption that √ n is rational leads to a contradiction of the fundamental theorem of arithmetic by the following steps:Suppose that √ n=, where a and b are positive integers, b≠q0. Explain why...
To show that √ n is an irrational number unless n is a perfect square, explain how the assumption that √ n is rational leads to a contradiction of the fundamental theorem of arithmetic by the following steps:Assume that n is not a perfect square, that is, does not belong to the seque...
Determine the x-intercepts of the polynomial function y=-6(x+7)^4 + 5. If a and b the root of the equation x^2 - x + 1 = 0, then a^2009 + b^2009 is equal to what? How do you find remaining zeros of a polynomial function? Is a square a rectangle? What are the x-inter...
Over the past couple years or so there has been a dramatic rise in the number of HTML5 games around on the Web, thanks in no small part to the HTML5 gaming engines that are making their development much easier.In this tutorial, I'm going to show you how to build a simple space-...
points. In a regression analysis, the goal is to determine how well a data series can be fitted to a function that might help to explain how the data series was generated. The sum of squares is used as a mathematical way to find the function thatbest fits(varies least) from the data....
To determine the required sample size, we performed a power analysis (Dattalo 2008) of a small-sized effect (0.2 SD) with a power of 85\(\%\) in a between-subjects experiment. It showed that a minimum of 277 participants were needed in total. This was in line with the suggested mini...
When the coefficient of x2 is 1, as in this case, then to make the quadratic on the left a perfect square trinomial, we must add a square number. What square number must we add? We must add the square of half of coefficient of x. The trinomial will then be the square of (x +...
