A geometric sequence is defined recursively by a(1)=40 and a(n)=a(n-1)*(1/2). a) write out the first four terms of the sequence

b) is the 9th term of this sequence larger or smaller than 1/10? show the calculation that you use to determine your answer.

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

i would say c

step-by-step explanation:

the answer is b.

surface area: 169π

volume: 366π

i got it down.
