A=24.56
Work circle= 3.14 times 4 Sq/4= 12.56
Trapezoid= 1/2 (4)(2+4)
B.16.75
OR 12.28+ Sq rt of 20
        
             
        
        
        
Hello,
<span>List all possible rational roots of the polynomial equation x3 – x2 – x – 3 = 0
Answer -1,1,-3,3
but none is a root.

The Taylor series is defined by:

Let a = 0.
Then its just a matter of finding derivatives and determining how many terms is needed for the series.
Derivatives can be found using product rule:

Do this successively to n = 6.

Plug in x=0 and sub into taylor series:

If more terms are needed simply continue the recursive derivative formula and add to taylor series.
 
        
        
        
Answer:
3240°
Step-by-step explanation:
For a regular icosagon,
sum of interior angles measure=180(n-2)°
180(20-2)
180(18)=3240°
