Answer:
We are given that the rate of change is proportional to its size S
So,
Integrating both sides
S is the population after t hours
is the initial population
Now we are given that After 6 hours there will be 1200 bacteria
So,
a)Now the population after t hours as a function of t;
b) What will be the population after 7 hours?
Substitute t = 7 hours
A bacteria culture starts with 200 bacteria
c) How long will it take for the population to reach 1750 ?
So, it will take 7.2 hours for the population to reach 1750
3/10 in
<span>1 in =(1/12)ft </span>
<span>1 ft =(1/5280) mi </span>
<span>3/10 in=3/10*(1/12)*(1/5280) mi </span>
Answer:
x=28
Step-by-step explanation:
180-42=138 since a triangle adds up to 180
2x+10+3x-12=138 then combine like terms
5x-2=138 add 2 to both sides
5x=140 divide each side by 5
x=28
Can't see question properly. Whats the power on the second number?
