Answer:
8i
Step-by-step explanation:
<em>When a quantity is raised to a fractional power, you need to root it to the power of the denominator. </em>
<em>For example, </em><em>(-64)^(1/2) = √(-64) </em>
<em>Since you are taking the root of a negative, you will need to put an </em><em>i</em><em> (imaginary) in your answer.</em>
Answer:
C. 4(cos(300°) +i·sin(300°))
Step-by-step explanation:
The magnitude will be ...
magnitude = √(2^2 +(-2√3)^2) = √(4+12) = 4
The negative imaginary part puts the angle in the 4th quadrant. The answer choice with a magnitude of 4 and a 4th-quadrant angle is ...
4(cos(300°) +i·sin(300°))
__
If you want to figure the angle, it will be ...
angle = arctan(Im()/Re()) = arctan(-2√3/2) = arctan(-√3) = -60°
The corresponding 4th-quadrant angle is 300°.

<em>Comment on answer choices</em>
Answer choice A is <em>another representation of the same number</em>. Typically, we want the magnitude to be positive in polar form, so that answer can be avoided on those grounds.
average rate of change of work from max. height unitil it reaches the ground 4 ≥ t .
<h3>WHAT IS AVERAGE RATE ? </h3>
The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function. A method that determines the amount of change in one item divided by the corresponding amount of change in another is known as an average rate of change function.
<h3>CALCULATION</h3>
h(t)=-16t^2+144t
= 16t [ 4 - t ]
4 - t ≥ t
domain is (0,4)
t is the time , time must be positive so domain starts from zero .
