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 <u>rational</u> because it can be put into a fraction (
) that is made up of whole numbers.
The second number is
.
- This number is <u>irrational</u> 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
- There is a pattern so the number is <u>rational</u>.
- Usually a pattrn means it can be put into a fraction.
The fourth number is
. This equals 4 if you solve it out.
- Since we just get 4, that certainly can be put into a fraction of whole numbers, so this is <u>rational.</u>
If you would like to know how much profit on each share did he make, you can calculate this using the following steps:
$12,000 / $8 = 1,500 shares
$15,000 / 1,500 shares = $10 per share
x% of $8 is $10
x/100 * 8 = 10 /*100/8
x = 10 * 100 / 8
x = 125%
125% - 100% = 25%
Miguel made 25% ($2) profit on each share.

Step-by-step explanation:
Opposite angles of a cyclic quadrilateral are supplementary, so:

This means that
