Multiple Choice

Solve for the indicated variable.
- $\mathrm { I } - \mathrm { I } _ { 0 } = \left( \mathrm { I } _ { 1 } - \mathrm { I } _ { 0 } \right) 10 ^ { - \mathrm { kt } }$ , for $\mathrm { t }$

• A) \(\mathrm { t } = - \frac { 1 } { \mathrm { k } } \log \left( \mathrm { I } - \mathrm { I } _ { 1 } \right)\)
• B) \(t = - \frac { 1 } { k } \log \frac { \mathrm { I } } { \mathrm { I } }\)
• C) \(t = - \frac { I - I _ { 0 } } { k \left( I _ { 1 } - I _ { 0 } \right) }\)
• D) \(t = - \frac { 1 } { k } \log \frac { \mathrm { I } - \mathrm { I } _ { 0 } } { \mathrm { I } _ { 1 } - \mathrm { I } _ { 0 } }\)
