Answer:
x=7
Step-by-step explanation:
Solve the absolute value and you immediately find that both sides have to equal zero.
At hour one, there is 1 organism. At hour two, there is five more organism. At hour three. there will be 6 x 5 = 30 more organisms, etc
This is a geometric sequence with a = 1 (i.e. number of organisms at hour one), r = 5 (number of reprications per hour).
The total number of organisms at hour seven is the sum of the first seven terms of the sequence given by a(r^n - 1)/(r - 1) = 1(5^7 - 1)/(5 - 1) = (78125 - 1)/4 = 78124/4 = 19,531
Find the least one. 3964. Which of the other two is lesser? 4000. Only one remains. Write these three in order now.
I believe that the answer would be 45
