Explanation:
The expression which represent the polar form of complex number -4i when converted into the polar form is 4(cos π+ isin π)
<h3>What is complex number?</h3>
A complex number is the combination of real and imaginary number. In a complex number, real part and imaginary part of number is written together. For example,
a+bi
Here, (a) is the real part while (b) is the imaginary part.
The complex number which need to convert into its polar representation is,
n=-4i
It can be rewritten as,
n=0-4i
The radius r of the polar form is,
r²=0²+(-4)²
r²=0+16
r=4
The value of cos theta is,
tan θ=0/-4
θ=tan⁻¹(0)
θ=π
Thus, the polar form is,
z=rcos θ+(r sin θ)i
z=-4(cos π+ isin π)
Thus, the expression which represent the polar form of complex number -4i when converted into the polar form is 4(cos π+ isin π)

Answer:
sure and the answer is 1.902071808e+13
Explanation:
The correct answer is - b. Savannas have shrubs and isolated trees, while grasslands contain grasses, flowers, and herbs.
The difference of the two mainly comes as a result of the climate that affects this regions. Even though both of them are predominantly lands covered with grasses, there are differences that are obvious.
The grass in the savanna is yellow and dried for the biggest part of the year, there's also lots of shrubs, and also small communities of trees that are on certain distance from one another.
The grass in the grasslands is green for the biggest part of the year because there's much more rain which is also better distributed throughout the year. This also allows lots of flowers and herbs to grow in the grasslands, thus making it have a nice spectrum of colors in between the greenness.
The guideline set by the American Academy of Family Physicians for an e-visit is that E-visits are available only to established patients who have previously received care from the physician’s practice
<h3>What is a Guideline?</h3>
This refers to the set of rules that a process must follow for its smooth running of operations.
Hence, we can see that one of the guidelines that is set by the American Academy of Family Physicians for an e-visit is that E-visits are available only to established patients who have previously received care from the physician’s practice.
