In writing the equation to construct a rectangle of specified perimeter and area, the perimeter,was wrongly written as 24 instead of 42.The length of a side
To find the gradient of the line take any two points on the line (x1, y1) and (x2, y2). The gradient=change in ychange in x=y2−y1x2−x1 Example 2.1 Find the gradient of the lines given in Figure 2.2(a)–(c) and the equation for the line in each case. Sig...

Unit vectors have length 1. To find the unit vector in the same direction as a vector r divide the vector by its length: rˆ = r|r|. 8. Any vectors in the plane can be represented in terms of i = (1, 0) and j = (0,1) and in three dimensions by i = (1,0, 0)...
The naming of second-degree equations, "quadratic," has to do with the roots of mathematics, which lie in geometry. Here's how it works: Imagine that a rectangle is two feet wider than it is long. How is the area of that rectangle expressed? Give the length of the rectangle a name ...
The other term is either plus or minus two times the product of the square roots of the other two terms. The -7 term immediately says this cannot be a perfect square trinomial. The task in completing the square is to find a number to replace the -7 such that there will be a perfect...
