Calculate the intrinsic value of Rio Tinto in each of the following scenarios by using the threestage growth model of Spreadsheet $18\mathrm{.}1.$Treat each scenario independently, meaning reset to the original$$data for each part. The goal is to see how the intrinsic$$value is affected by the individual$$factors below. Provide$$calculations for all parts.a$$The terminal growth rate will be$6\%.$ What is the intrinsic value now?b$$Rio Tintos actual beta is $1\mathrm{.}2.$ What$$is the intrinsic$$value now?c$$The market risk premium is $7\mathrm{.}5\%.$ What is the intrinsic value now?
