Answer:
8
Step-by-step explanation:
Nth term of a geometric sequence is given as:
...(1)
Plugging n = 9, a = 3 and r = 2 in the above equation, we find:

... (2)
Comparing equations (1) & (2), we obtan:
(n - 1) = 8
Answer:
n = 3
Step-by-step explanation:
We use log to find <em>n.</em>
log₂(8) = 3
2³ = 8
Answer:
75%
Step-by-step explanation:
Price for company A:
p(A) = 10 + 5*h
Price for company B:
p(B) = 7*h
,where h is the hours.
To find the hours after which the prices for both are going to be the same, we set the price for A equal to the price of B and calculate h.
10 + 5*h = 7*h <=>
2*h = 10 <=>
h = 10/2 <=>
h = 5 hours
