The fact-based and emotional arguments that he used were:
- Stating that expansion was needed to have access to ports (facts)
- He mentioned sustaining the glory of France (emotional)
<h3>What is an Argument?</h3>
This refers to the use of words to try and convince a person through the use of logic and other persuasive appeals.
Hence, we can see that from the given speech, Jules Ferry made use of both emotional and logical appeals about the need for continued colonial expansions and they are listed above.

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)
