These drawings depict the steps to get the perpendicular line using a compas (and maybe a ruler)
remember that a line goes through 2 points so we need 2 different points to construct our perpendicular line
the first one is wrong because it doesn't constraint it to be perpendicular
it only has 1 point,
2nd is wrong as well, has only 1 point, the center
3rd is right
4th is correct, hold a sec
how did that 2nd upper arc have same beginig pointn for compass?
3rd on is answer

Also I took the test
2000 dollars is owed with 9% interest rate.
Now, assuming that for 10 years, it is not being paid.
Let's calculate for the money that is now owed.
=> 2000 dollars * . 09 = 180 dollars for 1 years
=> 180 dollars * 10 years = 1800 dollars
=> 2000 + 1800 = 3800 dollars for 10 years.
