A wire of length 3x is bent into the shape of a square Express the area A of the square as a function of x?
The square is formed from a wire the length of 3x, which forms a perimeter of the same length. Because each side of the square is one fourth of the total perimeter (1 out of 4 equal sides), each side is 3x/4. The square of one side of a square is equal to the area of that square, so the area is (3x/4)2 = (9/16)x2.The answer is then A = (9/16)x2.
Two lines that lie in the same plane and are always the same distance apart?
parallel lines
Are skew lines parallel?
No. If they are parallel, then a plane exists which both lines lie in. Skew lines can not be on the same plane.
Is 6 symmetrical?
no ****************** Draw a vertical line through the centre of the number 6. As both sides are not identical, then there is no symmetry. Do the same with a capital H, and there is symmetry, as both sides of the vertical line are identical.
How can you find a unit vector in the same direction as the given vector?
Divide the vector by it's length (magnitude).
