A culture of bacteria doubles every 2 hours.  If there are 500 bacteria at the beginning, how many bacteria will there be after 24 hours?

Is this sequence arithmetic or geometric?

What is the initial term?

What is the rate of change (common ratio or common difference)?


Solution: There are 500 bacteria to start, doubling every 2 hrs..

<span><span>Such bacterial growth is a geometric sequence with a common ratio of 2.  </span></span>

<span><span>The number of times the bacteria doubles is 12 times during a 24 hour period.
</span></span>

<span><span>The starting number is 500 and the common ratio is 2 hours.   The total number of bacteria is 2,048,000.
</span>
</span>

<span>Determine if the sequence is geometric.  If it is, find the common ratio.</span>

9).  - 1, - 6, - 36, 216, ...... Geometric - Yes, Common Ratio is - 6

9). - 1, - 1,  4,  8,......  Geometric - No


10). 4, 16, 36, 64, ..... Geometric - No

10). - 3, - 15, - 75, - 375,......Geometric - Yes, Common Ratio is 5


11). - 2, - 4, - 8, - 16,...... Geometric - Yes,  Common Ratio is 2

11). 1, 5, 25, - 125,...... Geometric - Yes, Common Ratio is - 5



Hope this helps!!!!!

600+15y=750.<br> solve for y<br> can I as well have the way you solved for y?
Pie
1.)subtract 600 from 750 in order to simplify
2.)divide by 15 on both sides to get y alone. Doing this cancels the 15 on the y and makes the right side equal 10
3.)y=10

What solution do 2x2 - 13x + 21 = 0 and 2x2 + 9x - 56 = 0 have in common? Round your answer to the nearest tenth if necessary.
lys-0071 [83]
So if we want to know the common solution(s) to a system of 2 equations, So we can just set both equations equal to each other and solve for the x value(s). That’s where I start below;

2x^2-13x+21 = 2x^2+9x-56
2x^2 cancels out and moving everything to one side and anything with an x variable to the other side we have then;
-22x=-77
22x=77 by cancelling the negative signs
x=77/22 therefore x=7/2 or 3.5

Hope this helps you. Any questions please ask.
