Answer:
140
Step-by-step explanation:
- 143,622 bacteria present on day 15
- the bacteria doubles twice a day
that means each day backwards, the bacteria is four times less the day before
therefore:
- on day 14, the number of bacteria is 143,622 / 4
which is 35,905.5
and so on!
so:
- day 13 = 8,976.375
- day 12 = 2,244.09375
- day 11 = 561.0234375
- day 10 = 140.255859375
this rounded to the nearest whole number is
= 140 bacteria
(you can't have a part of a bacteria!)
hope this helps! :)

Answer:
x = 2![\sqrt{66}](https://tex.z-dn.net/?f=%5Csqrt%7B66%7D)
Step-by-step explanation:
x = ![\sqrt{2^2+8^2+14^2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%5E2%2B8%5E2%2B14%5E2%7D)
= ![\sqrt{4+64+196}](https://tex.z-dn.net/?f=%5Csqrt%7B4%2B64%2B196%7D)
= ![\sqrt{264}](https://tex.z-dn.net/?f=%5Csqrt%7B264%7D)
= 2![\sqrt{66}](https://tex.z-dn.net/?f=%5Csqrt%7B66%7D)
