a culture started with 2000 bacteria.after 8 hours it grew to 2400 predict how many bacteria will be present after 19 hours?
1 answer:
This is a geometric sequence but you don't know the growth factor, so you would solve for it first.
2400= 2000(x)^8
1.2= x^8
x= 1.02305188
You can round depending on what your teacher prefers.
Now you can plug in your growth factor and solve.
A(19)= 2000(1.02305188)^19
A(19)= 2000(1.54189747739)
A(19)= 3083.79495477
After 19 hours, 3,084 bacteria will be present.

Answer:
w = 3
Step-by-step explanation:
-6(w - 4) + 8W=6(w + 2)
-6w + 24 + 8w = 6w + 12
2w + 24 = 6w + 12
12 = 4w
3 = w
