Answer:
Here we just want to find the Taylor series for f(x) = ln(x), centered at the value of a (which we do not know).
Remember that the general Taylor expansion is:

for our function we have:
f'(x) = 1/x
f''(x) = -1/x^2
f'''(x) = (1/2)*(1/x^3)
this is enough, now just let's write the series:

This is the Taylor series to 3rd degree, you just need to change the value of a for the required value.
Answer:
If it says (10a + 4): 40a + 16
If it says (10a - 4): 40a - 16
Step-by-step explanation:
If it's an equilateral quadrilateral, that means all sides are equal. So you would multiply the given side by the number of sides. Then simplify you equation.
I can't read it if it says (10a + 4) or (10a - 4) so i'll just do both and you can use which one it says.
If it says (10a + 4):
4(10a + 4)
40a + 16
If it says (10a - 4)
4(10a - 4)
40a - 16
So it was 75 to 25 people. that would be decrease by 66.66666666 (forever) percent
