Answer:
a) there is s such that <u>r>s</u> and s is <u>positive</u>
b) For any <u>r>0</u> , <u>there exists s>0</u> such that s<r
Step-by-step explanation:
a) We are given a positive real number r. We need to wite that there is a positive real number that is smaller. Call that number s. Then r>s (this is equivalent to s<r, s is smaller than r) and s is positive (or s>0 if you prefer). We fill in the blanks using the bold words.
b) The last part claims that s<r, that is, s is smaller than r. We know that this must happen for all posirive real numbers r, that is, for any r>0, there is some positive s such that s<r. In other words, there exists s>0 such that s<r.
 
        
             
        
        
        
Answer:
 3 strain would still alive after 48 hours
Step-by-step explanation:
Initial population of virus = 40000 grams 
A certain virus is dying off at a rate of 18% per hour. 
We are supposed to find  how much of the  strain would still be alive after 48 hours
Formula : 
 =Initial population
=Initial population
N(t)= Population after t hours 
r = rate of decrease = 18% = 0.18
t = time = 48 hours 
So,the  strain would still be alive after 48 hours=
Hence 3 strain would still alive after 48 hours
