Answer: it will take 18.2 years
Step-by-step explanation:
We would apply the formula,
y = ab^t
Where
a represents the initial amount of bacteria.
t represents the doubling.
From the information given
a = 10
t = 1 hour
Since after 1 hour, the amount of bacteria multiplies by 2, then
y = 2 × 10 = 20
Therefore
20 = 10 × b^1
Dividing through by 10, it becomes
2 = b
The equation becomes
y = 10(2)^t
For 3,000,000 bacteria, then
3000000 = 10(2)^t
3000000/10 = (2)^t
300000 = (2)^t
Taking log of both sides, it becomes
Log 300000 = tlog2
5.477 = 0.301t
t = 5.477/0.301
t = 18.2 years

these are right answers am'l right??
Answer:
and
Step-by-step explanation:
Let the number be x.
The product of 2 and the number x, is written as
If the product of 2 and the number x is ¾;
Then we can write the equation:
When we divide both sides by 2, we get:
This implies that:
This simplifies to
Therefore the statements which are true are:
and
It is basically 8 thousand plus one thousand two hundred so your answer would be 9200
Hopes this helps:
Answer: x = 0 the equal sign has to have a line going through it.
The denominator must not equal 0. So the domain is x = 0 the equal sign has to have a line going through it.
