Multiple Choice

 Find dydx\text { Find } \frac { d y } { d x } x=7eθx = 7 e ^ { \theta }
y=eθ7y = e ^ { - \frac { \theta } { 7 } }


A) dydx=149eθ7\frac { d y } { d x } = \frac { 1 } { 49 } e ^ { - \frac { \theta } { 7 } }
B) dydx=49e7θ\frac { d y } { d x } = 49 e ^ { - 7 \theta }
C) dydx=17e87θ\frac { d y } { d x } = - \frac { 1 } { 7 } e ^ { - \frac { 8 } { 7 } \theta }
D) dydx=7e7θ\frac { d y } { d x } = 7 e ^ { - 7 \theta }
E) dydx=149e87θ\frac { d y } { d x } = - \frac { 1 } { 49 } e ^ { - \frac { 8 } { 7 } \theta }
