Given:
Initial number of bacteria = 3000
With a growth constant (k) of 2.8 per hour.
To find:
The number of hours it will take to be 15,000 bacteria.
Solution:
Let P(t) be the number of bacteria after t number of hours.
The exponential growth model (continuously) is:
Where, is the initial value, k is the growth constant and t is the number of years.
Putting in the above formula, we get
Taking ln on both sides, we get
Therefore, the number of bacteria will be 15,000 after 0.575 hours.
Answer:
You can buy 40 tacos
You have enough money
Step-by-step explanation:
Given
--- missing from the question
Required
Determine if you have enough amount
The number of Tacos that $20 can afford is calculated as:
So, we have:
-- i.e. the number of Tacos will go round the 37 students
Hence, you have enough money
We have been given that Mark had $436.
Further, we are given that Chris has $86 lesser than what mark had.
Let us assume that Chris has $x. Therefore, we can set up an equation:
(Amount Chris had) + $86 = (Amount Mark had)
Upon subtracting 86 from both the sides, we get:
Therefore, the required expression that represent the amount of money that Chris had is .
