A certain bacteria colony doubles in size every day for 20 days, at which point it reaches the limit of its habitat and can no l

erma4kov [3.2K]

Answer:

(E). 19

Step-by-step explanation:

Let original population of each colony be P.

We have been given that a certain bacteria colony doubles in size every day, so bacteria colony is growing exponentially. After x days, the population of bacteria would be:

$P(2)^x$

The population after 19 days will be $P(2)^{19}$ for each colony.

The total population of both the colonies at that point will be $P(2)^{19}+P(2)^{19}=2P(2)^{19}=P(2)^{20}$ which is what the habitat's limit is.

Therefore, it will take 19 days for two bacteria colonies to reach the habitat's limit and option E is the correct choice.

If x+y = 2y-x+1=5 pls can you give me a well explained solution

ohaa [14]

Answer:

Solution : x = 2

y = 3

Step-by-step explanation:

x+y = 2y-x+1=5

x + y = 5 --------> equ 1

2y - x +1 = 5

2y - x = 5 - 1

2y - x = 4

-x + 2y = 4--------> equ 2

add equ 1 & equ 2

3y =9

y = 9/3 = 3

Put y = 3 in equ 1

x + 3 = 5

x = 5 - 3 = 2

Solution : x = 2

y = 3
