Answer:
The given series can be written as
4
∑ (5)^i
i = 0
We know that the series is
1+5+25+125+625
This is equal to
(5)^0 + (5)^1 + (5)^2 + (5)^3 + (5)^4
Thus,
For i from 0 to 4,
We get the general representation.
Number of angles = number of sides
180 - 120 = 60 (calculating the exterior angle)
360 / 60 = 6
There are 6 sides.
Hope this helps! :)

Step-by-step explanation:
v=s^3 s=3^4=81
v=(81)^3
v=531,441 cm^3
The midpoint of the line having the endpoints

and

is

basically average them
so given that the line has the endpoints of (-3,7) and (9,-2)
x₁=-3
y₁=7
x₂=9
y₂=-2
so the midpoint can be found by doing



the midpoint is
