Answer:
The number of ways are 40320.
Step-by-step explanation:
Consider the provided information.
Ms. Smith keeps eight different cookbooks on a shelf in one of her kitchen cabinets.
We need to determine the number of different ways to put eight cookbooks on the shelf.
We need to select 8 cookbooks taking 8 at a time.
So use the permutation formula:
Substitute n=8 and simplify.

Hence, the number of ways are 40320.
It’s four hundred eighty two and seventy three hundredths
Fixed expense because it is a monthly payment
Answer:
y^3 + 3^3
Step-by-step explanation:
1) Multiply each term of (y^2-3y+9) by y: y^3 - 3y^2 + 9y
2) Multiply each term of (y^2-3y+9) by 3: 3y^2 - 9y + 27
3) Add all of these terms together: y^3 + 27 = y^3 + 3^3
