I'm pretty sure the answer is 9y^3 + 105y^2 -2y + 2, but idk if the numbers you put next to the variables are suppose to be exponents or not...

Step-by-step explanation:

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

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;
