An investment of $1000 you made four years ago was worth $1200 after the first year, $1200 after the second year, $1500 after the third year, and $2000 today, a. compute the annual rate of return
b. calculate the mean and the median of the rate of return
c. compute the geometric mean

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
