2. Does the set of numbers form a Pythagorean triple? Explain.

1 answer:

7 0

So Pythagorean triples will always work with Pythagoras theorem which is a^2 + b2 = c^2 where c is the hypotenuse. So the biggest number (15) will be the hypotenuse so you must do (9^2) + (12^2) and if it is a triple you will get 15^2 so you do 81 + 144 which is 255 and 15^2 is 255 so therefore it is a Pythagorean triple because the numbers satisfy the equation. Hope this helps :)

Y equals volume of water, x equals time. If they ask to find the coordinates at one minute, then the first thing you should do is set x equal to 1. That leaves two possible answers. Finally you need to decide how much water is lost in one minute. if you need more help leave a comment.
