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:
50m
Step-by-step explanation:
The triangles are similar, so their sides are in ratio:
BC/BE=AD/ED
j/46=25/23
j=(25/23)(46)=50
For 1 the equation of the parabola is y = x^2 - 8x + 3
For 2 the equation of the parabola is y = -2x^2 - 3x + 1
For 3 the equation of the parabola is y = -x^2 + 5x - 4
