The distance formula is
simply a variation of the theorem. The method is the same with the Pythagorean
however we are now dealing with 2 sets of points instead of 2 lengths. <span>
In the distance formula, the lengths are derived from the
(x1,y1)->(x2,y2) coordinate points and the formula simplified. We still
square the difference of x’s and difference of y’s to get our two squares then
square root the sum to give our length. While the Pythagorean theorem is
directly the sum of the square of the other two sides.
<span>Nevertheless, both formulas work on the same principle.</span></span>
Answer:
Step-by-step explanation:
Well, what happens when you multiply a number by 10? 1*10 is just 10 of course, 2*10 is 20, 3*10 is 30 and so on. This pattern continues, so if you multiply anything by 10 you take whatever it was and move everything to the next highest "place. so for 2, which starts in the ones place you move it to the tens place. For whole numbers you can think of it as just adding a 0 to the end.
Anyway, for this it's asking what gets multiplied by 10 to get 25,960. Well, since it's a whole number realize that whatever this number was times 10 got a 0 added to it. so just take that last 0 away. 2,596
Another method is dividing by 10, which just does the opposite of multiplying by 10.
