Answer:
$10,530
Step-by-step explanation:
I = Prt
P = 19500
r = 0.06
t = 9
I= 19500 x 0.06 x 9
I = 10530
So, to evaluate a combination, there's a formula we use.
I don't remember the formula from the top of my head, lol, but this is how you solve them.
7 c 2
When doing combinations and permutations each number is always in a factorial. We always start with the number on the left.
7! That's the total amount. The number on the left divides into that.
7! / 2!
We're not done yet. Here's the tricky part. We also always divide the number on the left, in this case 7!, with the positive difference of both numbers given to us.
7 - 2 = 5
So, we have 7! / 5! / 2! = 21.
Hope that helped!
Let's work another one.
5 c 3
We have 5! / 3! ,but we need to also divide 5! by the positive difference of 5 and 3. We get 2.
So, 5! / 3! / 2! = 10.
If you have any questions then leave a comment. Good luck!
I apologize, I am stumped... I thought you would find either the centroid, circumcenter, or incenter of the triangle created but it didn't work quite right for me.
