question 203

Multiple Choice

Find the product or quotient, as indicated. Leave your answer in polar form.
-Find the product of $\mathrm { z } _ { 1 }$ and $\mathrm { z } _ { 2 }$ .
$\mathrm { z } _ { 1 } = 3 \left[ \cos \left( - 40 ^ { \circ } \right) + \mathrm { i } \sin \left( - 40 ^ { \circ } \right) \right] , \mathrm { z } _ { 2 } = 44 \left( \cos 180 ^ { \circ } + \mathrm { i } \sin 180 ^ { \circ } \right)$

• A) \(132 \left( \cos 220 ^ { \circ } + i \sin 220 ^ { \circ } \right)\)
• B) \(132 \left( \cos 140 ^ { \circ } + i \sin 140 ^ { \circ } \right)\)
• C) \(132 \left( \cos - 7200 ^ { \circ } + i \sin - 7200 ^ { \circ } \right)\)
• D) \(47 \left( \cos 140 ^ { \circ } + \mathrm { i } \sin 140 ^ { \circ } \right)\)
