5!x4!=2880 n<span>! is the factorial function</span>
Answer: 8/15, 15/8
Step-by-step explanation:
By the Pythagorean theorem, the length of the unknown side is

So, the tangents of the acute angles are 
I think you can solve it by doing this:
10(10,000+0.06)= Final Balance
6 months + 6 months = 1 year
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
She has to pay twice a year
Now that we know that just multiply 2 by 5 and you get 10. 10(10,000+0.06)= Final Balance
So it should be 100000.6
Not sure if that's right so ask someone to check
Sub 4 for every y
8x-2(4)=48
8x-8=48
ad 8 to both sides
8x=56
divide both sides by 8
x=7
