question 137

Multiple Choice

Write the complex number in trigonometric form r(c $$r ( \cos \theta + i \sin \theta )$$ ) , with $$\theta$$ in the interval [0 $$\left[ 0 ^ { \circ } , 360 ^ { \circ } \right)$$
- $5 - 5 \sqrt { 3 } i$

• A) \(5 \left( \cos 330 ^ { \circ } + i \sin 330 ^ { \circ } \right)\)
• B) \(5 \left( \cos 330 ^ { \circ } + \sin i 330 ^ { \circ } \right)\)
• C) \(10 \left( \cos 300 ^ { \circ } + i \sin 300 ^ { \circ } \right)\)
• D) \(10 \left( \cos 150 ^ { \circ } + i \sin 150 ^ { \circ } \right)\)

Definitions:

Action Potential

A quick electrical impulse that travels down a neuron's axon, triggering the release of neurotransmitters.

Repolarization Phase

A stage in the cardiac cycle following depolarization, where the heart muscle returns to its resting state by restoring the negative charge on the cell's membrane.

Neuromuscular Junction

The synapse or interface between a neuron and a muscle cell, allowing for the transmission of a nerve impulse to trigger muscle contraction.

Synaptic Vesicles

Small sacs located in nerve terminals that store neurotransmitters released during synaptic transmission.
