Express the given product or quotient as a factorial expression. assume that n > r > 0.
1. (n+1)n!
2. (n+8)! /n+8
3. 100 x 99 x 98
4. (n-1)(n-2)(n-3)

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
