Hi! =)
So,<em> 1 </em>lbs per week are equal to<em> 7.4999e-7</em> kilograms per second. We can use this to convert lbs per week to kg per second.
<em>721 * 7.4999e-7 = 0.000540741!</em> =)
Given:
The relation is
To find:
The equation for the given relation.
Solution:
(2,8) is an ordered pair of given relation. So, y=8 at x=2.
Similar,
It means, y-values are cube of x-values. So,
Therefore, the required equation for the relation is .
Answer:
here i finished!
hope it helps yw!
Step-by-step explanation:
The doubling period of a bacterial population is 15 minutes.
At time t = 90 minutes, the bacterial population was 50000.
Round your answers to at least 1 decimal place.
:
We can use the formula:
A = Ao*2^(t/d); where:
A = amt after t time
Ao = initial amt (t=0)
t = time period in question
d = doubling time of substance
In our problem
d = 15 min
t = 90 min
A = 50000
What was the initial population at time t = 0
Ao * 2^(90/15) = 50000
Ao * 2^6 = 50000
We know 2^6 = 64
64(Ao) = 50000
Ao = 50000/64
Ao = 781.25 is the initial population
:
Find the size of the bacterial population after 4 hours
Change 4 hr to 240 min
A = 781.25 * 2^(240/15
A = 781.25 * 2^16
A= 781.25 * 65536
A = 51,199,218.75 after 4 hrs
This is how the sketch should look on your graph!
