question 80

Multiple Choice

Calculate $\frac { \partial f } { \partial x }$ , and $\left. \frac { \partial f } { \partial y } \right| _ { ( 8,2 ) }$ when defined. $f ( x , y ) = 1100 - 16 x + 11 y$

• A) \(\frac { \partial f } { \partial x } = - 16\) , \(\left. \frac { \partial f } { \partial y } \right| _ { ( 8,2 ) } = 11\)
• B) \(\frac { \partial f } { \partial x } = 8\) , \(\left. \frac { \partial f } { \partial y } \right| _ { ( 8,2 ) } = 2\)
• C) \(\frac { \partial f } { \partial x } = - 16 y\) , \(\left. \frac { \partial f } { \partial y } \right| _ { ( 8,2 ) } = 11 x\)
• D) \(\frac { \partial f } { \partial x } = - 27\) , \(\left. \frac { \partial f } { \partial y } \right| _ { \{ 8,2 ) } = 27\)
• E) \(\frac { \partial f } { \partial x } = 11\) , \(\left. \frac { \partial f } { \partial y } \right| _ { \{ 8,2 ) } = 16\)
