Use the Pythagorean Equation to find the distance between points x and y

snow_tiger [21]

Start at point x and count down until you are in line with point y. (This will be five units). From the point you just ended at, count across until you get to point y. (This will be 9 units). Five units and nine units are the lengths of your two legs. The Pythagorean theorem is a^2+b^2=c^2. So you then take 5^2+9^2=c^2, or 25+81=c^2, or 106=c^2. Then square root each side, and get 10.2956=c. Therefore the distance between points x and y is 10.2956, or 10.3 if you choose to round.

Answer: See below.

Step-by-step explanation:

Let's go number by number.

Rational pretty much means you can put it into a fraction of whole numbers.

The first number is -81,572.

This number is rational because it can be put into a fraction ( $\frac{-81572}{1}$ ) that is made up of whole numbers.

The second number is $\sqrt{11}$ .

This number is irrational because it cannot be put into a fraction of whole numbers.
Keep in mind that most squareroots are irrational. Especially those that don't equal a whole number.

The third number is 5.636336333
