3.143
Step-by-step explanation:
Since you're rounded it to the third decimal, you look at the fourth one. And since the fourth one is 8, ur going round 2, which is the third decimal to 3.
Answer:
Beginning (t=0) population with flu is 23.
After 4 weeks, population with flu is 1250.
After an infinite amount of weeks, the population witf flu is 102000
Step-by-step explanation:
First question asks you to replace t with 0 because it says beginning.
102000/(1+4400e^-0)=102000/(1+4400)=102000/4401=23.17655 approximately. To nearest whole number this is 23.
After 4 weeks means we replace t with 4:
102000/(1+4400e^-4)
Calculator time:
1250.17142 which to nearest whole number is 1250
If t is super large, then e^-t is super close to 0.
So the limiting number is
102000/(1+4400×0)=102000/1=102000
Answer:
24 g
Step-by-step explanation:
In this context*, PPT means "parts per thousand", so the weight of salt is ...
(24/1000)×(1000 g) = 24 g
_____
* PPT is often used to mean "parts per trillion". The ambiguity between thousand and trillion, as well as the fact that "trillion" means different things in different countries, has led the National Institute of Standards and Technology (NIST) to discourage the use of that abbreviation.
Answer:
x=5, x=-9
Step-by-step explanation:
I am assuming the "x+1" is squared since there is more than one answer.
x+2=7
x+2=-7
x=5, x=-9
