question 203

Multiple Choice

Solve for the indicated variable. Assume the variable you are solving for must be greater than 0.
- $$P = \frac { A } { ( 1 + r ) ^ { 2 } } , \text { for } r$$

• A) \[r = \frac { P + \sqrt { P ^ { 2 } + A P } } { 2 }\]
• B) \[r = \frac { - P + \sqrt { P ^ { 2 } - A P } } { P }\]
• C) \[r = \frac { - \mathrm { P } + \sqrt { \mathrm { AP } } } { \mathrm { P } }\]
• D) \[r = \frac { P + \sqrt { \mathrm { AP } } } { 2 \mathrm { P } }\]
