a$.$ If the one$-$year discount factor is $0\mathrm{.}9058,$ what is the one$-$year interest rate?

Note: Do not round intermediate calculations. Enter your answer as a percent rounded to $2$ decimal places.

b$.$ If the two$-$year interest rate is $10\mathrm{.}4\%,$ what is the two$-$year discount factor?

Note: Do not round intermediate calculations. Round your answer to $4$ decimal places.

c$.$ Given these one$-$ and two$-$year discount factors, calculate the two$-$year annuity factor.

Note: Do not round intermediate calculations. Round your answer to $4$ decimal places.

d$.$ If the PV of $$10$ a year for three years is $$24\mathrm{.}69,$ what is the three$-$year annuity factor?

Note: Do not round intermediate calculations. Round your answer to $4$ decimal places.

e$.$ From your answers to $($c$)$ and $($d$),$ calculate the three$-$year discount factor.

Note: Do not round intermediate calculations. Round your answer to $4$ decimal places.
