Suppose You Want to Use the Midpoint Rule with N 16exdx\int _ { 1 } ^ { 6 } e ^ { - x } d x

Question 108

Multiple Choice

Suppose you want to use the Midpoint Rule with n = 4 and equal-length subintervals to approximate 16exdx\int _ { 1 } ^ { 6 } e ^ { - x } d x ? What is the approximation using the Midpoint Rule?


A) 52[e1+e9/4+e7/2+e19/4]\frac { 5 } { 2 } \left[ e ^ { - 1 } + e ^ { - 9 / 4 } + e ^ { - 7 / 2 } + e ^ { - 19 / 4 } \right]
B) [e9/4+e7/2+e19/4+e6]\left[ e ^ { - 9 / 4 } + e ^ { - 7 / 2 } + e ^ { - 19 / 4 } + e ^ { - 6 } \right]
C) 54[e13/8+e23/8+e33/8+e43/8]\frac { 5 } { 4 } \left[ e ^ { - 13 / 8 } + e ^ { - 23 / 8 } + e ^ { - 33 / 8 } + e ^ { - 43 / 8 } \right]
D) 52[e1+e7/2+e6]\frac { 5 } { 2 } \left[ e ^ { - 1 } + e ^ { - 7 / 2 } + e ^ { - 6 } \right]
E) [e1+e9/4+e7/2+e19/4]\left[ e ^ { - 1 } + e ^ { - 9 / 4 } + e ^ { - 7 / 2 } + e ^ { - 19 / 4 } \right]
