Answer:
B) 5x^2
Step-by-step explanation:

We can divide 50 by 2, we get 25 and we can cancel out x from x^5.
Therefore, we get

= √25x^4
When we take the square root of 25, we get 5 and √x^4 = x^2.
Taking the square root, we get
= 5x^2
Answer: B) 5x^2
Thank you.
Answer:
Yes, but it is not linear. It is exponential : 
Step-by-step explanation:
On the first day we have 5 bacteria.
On the second day we will have 5*2 = 10 bacteria.
On the third day we will have 10*2 = 5*2*2 = 5*2^2 = 20 bacteria.
On the fourth day we will have 20*2 = 5*2*2*2 = 5*2^3 = 40 bacteria.
We can see that
,
where x is a number of days and f(x) gives us the number of bacteria.
6.05 because the 5 is in the hundredths place...
