Answer:
(5,0) and (1,0)
Step-by-step explanation:
you can set each factor equal to zero:
-x + 5 = 0
-x = -5
x = 5
x - 1 = 0
x = 1
18000 dollars invested with 5% interest.
=> 18 000 dollars * 0.05 = 900 dollars for annual interest rate.
Now, how much interest will he be earning in 3 years?
=> first year = 18 900 dollars * .05 = 945 dollars for the 2nd year
=> 2nd year = 18 900 dollars + 945 = 19 845 dollars
19845 * .05 = 992.25
=> 3rd years = 19845 + 992.25 = 20837.25 total amount he will get back.
For interest = 900 + 945 + 992.25 = <span>$2837.25</span>
Use the Pythagorean theorem.
it doesn't matter which value is which since we are looking for the hypotenuse, so we would plug in given values:

From here we do the math to solve for c

Final answer ---->
C=10
You have to turn 80% into a decimal.
12/.80 = 15
