Answer:
15625/4096
Step-by-step explanation:
The sequence is geometric with first term 1 and common ratio 5/4. The general term is ...
an = a1·r^(n-1)
an = 1·(5/4)^(n-1)
Then the 7th term is ...
a7 = (5/4)^(7-1) = 15625/4096
Answer:
(0,0)
Step-by-step explanation:
If the line is crossing the origin then that means both the x and y intercepts are (0,0)
The surface area of a sphere is

where r is the radius;
The circumference is

so that

using this value we can evaluate the surface area of 1 ball as:

For 100 ball you get:
