question 21

Multiple Choice

Find the second derivative of the function.
- $$r = \left( \frac { 1 + 8 \theta } { 8 \theta } \right) ( 8 - \theta )$$

• A) \(\frac { \mathrm { d } ^ { 2 } r } { d \theta ^ { 2 } } = \frac { 2 } { \theta ^ { 3 } }\)
• B) \(\frac { \mathrm { d } ^ { 2 } r } { d \theta ^ { 2 } } = \frac { 1 } { \theta } - \theta\)
• C) \(\frac { d ^ { 2 } r } { d \theta ^ { 2 } } = - \frac { 2 } { \theta ^ { 3 } } - 1\)
• D) \(\frac { d ^ { 2 } r } { d \theta ^ { 2 } } = - \frac { 1 } { \theta ^ { 2 } } - 1\)
