Answer:
t = -24*log(2/3)
Step-by-step explanation:
The expression is:
V = 22,500*10^(-t/12)
Replacing with V = 10,000 and isolating t, we get:
10,000 = 22,500*10^(-t/12)
10,000/22,500 = 10^(-t/12)
4/9 = 10^(-t/12)
(2/3)² = 10^(-t/12)
2*log(2/3) = -t/12
-12*2*log(2/3) = t
t = -24*log(2/3)
Step-by-step explanation:
If we calculate so there are 120 sec in 2 min
So we will divide 120 by 15 = 8
It means they will be doubled 8 times
So if bacteria are now 10 so 10 × 8 = 80
There will be 80 bacteria in 2 min
Answer:
It is by contract the same amount every month.
Step-by-step explanation:
I think the correct answer is B.
1200•1.07= 1284
1284•1.07= 1373
1373•1.07=1469
B is the closest
The domain of the graph is [-3, 2) and the range is (-4, 5]
<h3>How to determine the domain and the range?</h3>
From the given graph, we have the following highlights:
- Minimum x value = -3 (closed circle)
- Maximum x value = 2 (open circle)
- Minimum y value = -4 (open circle)
- Maximum y value = 5 (closed circle)
Open circles are represented with () while closed circles are represented with []
Hence, the domain of the graph is [-3, 2) and the range is (-4, 5]
