The Half-Life of Titanium 45 Is $3.1$ Hours If the Formula $\mathrm { P } ( \mathrm { t } ) = \left( \frac { 1 } { 2 } \right) ^ { \mathrm { t } / 3.1 }$

question 287

Multiple Choice

The half-life of Titanium 45 is $3.1$ hours. If the formula $\mathrm { P } ( \mathrm { t } ) = \left( \frac { 1 } { 2 } \right) ^ { \mathrm { t } / 3.1 }$ gives the percent (as a decimal) remaining after time $t$ (in hours) , sketch $P$ versus t.
