question 435

Multiple Choice

Find the product. Write the product in rectangular form, using exact values.
-[7( $\left. \left. \cos 45 ^ { \circ } + \mathrm { i } \sin 45 ^ { \circ } \right) \right] \left[ 2 \left( \cos 90 ^ { \circ } + \mathrm { i } \sin 90 ^ { \circ } \right) \right]$

• A) \(- 14 \sqrt { 2 } - 14 \sqrt { 2 } \mathrm { i }\)
• B) \(7 \sqrt { 2 } - 28 \sqrt { 2 } \mathrm { i }\)
• C) \(2 \sqrt { 6 } - \sqrt { 2 } i\)
• D) \(- 7 \sqrt { 2 } + 7 \sqrt { 2 } i\)
