AC is the geometric mean. Solve it using this proportion:

Now fill in the values we know:

Cross multiply to get

That means that
AC =
, which, in decimal form is
AC = 11.40175425
Answer:
y = -
x + 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = -
, then
y = -
x + c ← is the partial equation
To find c substitute (8, - 9) into the partial equation
- 9 = - 20 + c ⇒ c = - 9 + 20 = 11
y = -
x + 11 ← equation of line
You would get the annual salaries by dividing each total salary by the number of years it took to earn it. For example, to get the physician's annual salary, you would divide 5,610,000 by 30 to get an answer of $187,000.
