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)

Explanation:
The total cost to produce 50 oatmeal cookies is $20.
<h3>
Total cost to produce</h3>
First step is to calculate the total cost to produce 100 cookies:
Total cost to produce= Average total cost × Quantity
Total cost to produce=$.25×100
Total cost to produce=$25
Second step is to calculate the total cost to produce 50 cookies:
Total cost to produce=$25-($0.10 ×50)
Total cost to produce=$25-$5
Total cost to produce=$20
Inconclusion the total cost to produce 50 cookies is $20.
