question 124

Multiple Choice

Solve for the indicated variable. Assume the variable you are solving for must be greater than 0.
- $$r m = t ^ { 2 } - m t , \quad \text { for } t$$

• A) \[\mathrm { t } = \frac { \mathrm { m } + \sqrt { \mathrm { m } ^ { 2 } - 4 \mathrm { mr } } } { 4 }\]
• B) \[\mathrm { t } = \frac { \mathrm { m } + \sqrt { \mathrm { m } ^ { 2 } + 4 \mathrm { rm } } } { 2 }\]
• C) \[\mathrm { t } = \frac { \mathrm { m } + \sqrt { \mathrm { m } ^ { 2 } + 4 \mathrm { mr } } } { 2 \mathrm {~m} }\]
• D) \[\mathrm { t } = \sqrt { \mathrm { mr } - \mathrm { m } }\]
