I think u have to put the interest rate so we have more information
Answer:
She can chose 2 books from 8 books in 28 different way.
Step-by-step explanation:
In the given scenario the member has to chose 2 books from a group of 8 books. The order of choosing books does not matter. For example if the books are A,B,C,D,E,F,G and H, and the member picks books A and B or books B and A, she is picking up the same books. This means order of selection does not matter here, so this is a problem of combinations.
We have to form combination of 8 books taken 2 at a time i.e. 8C2
The general formula of combination is:
Using the values of n=8 and r=2, we get:
This means, she can chose 2 books from 8 books in 28 different ways.
The shape of the graph is very similar to a natural logarithm, which is ln(x). ln(x) has an asymptote at x=0. Shift the graph 3 units to the left and you have the graph of ln(x+3), which has an asymptote at x= -3. Also, when x=0, ln(x+3) is about 1. I think ln(x+3) is the answer. Check this online graph to see if this matches:

Have a nice day!
Ruben has 6 new books for his collection. This increases his collection by 12%
Let x be the number of books Ruben has before 6 new books added
x + 12% of x = x+6
x + 0.12x = x+6
1.12 x = x+6
Subtract x on both sides
0.12x = 6
Divide by 0.12
x = 50
6 new books are added for his collection
So 50 + 6 = 56
He have 56 books now.
