Where multiples and sub-multiple of units are used?
these are used to express very large number small and very small
What is the distance between the two points -2 and 2 3 and -2?
The distance between two points specified as number pairs is the hypotenuse of a right triangle formed by the horizontal line joining the two values of x and a vertical line joining the two values of y, For the stated pairs, these lines have length |(-2 - 3)| = 5 and |(-2 - 2)| = 4, respectively. From the Pythagorean theorem, the distance is then: sq rt (52 + 42) = sq rt 41 = about 6.4 units.
What is the number of square units o the surface of something?
