Answer:

dirk =13.25 hours

charlie =11 75 hours

Step-by-step explanation:

c+d=25------(1)

d-1.5=c-----(2)

from (1),

c+d=25

c=25-d-----(3)

substitude (3) into (2)

d-1.5=c

d-1.5=25-d

2d=26.5

d=13.25

if d=13.25 hours

c+d=25

c+13.25=25

c=25-13.25

c=11.75

The population of a certain species of bacteria doubles every hour. Use the following

elena55 [62]

Answer:

The bacteria will grow from 1 to 1024 in 10 hours

Step-by-step explanation:

Given

P_0 = 1

P = 1024

We have to find time

Putting values in the formula

$P = P_0(2)^t\\1024=(1)(2)^t$

Anything multiplied with 1 remains the same

$1024=2^t\\2^{10} = 2^t$

Using the property "when bases are same, the exponents can be put equivalent"

t = 10 hours

Therefore, the bacteria will grow from 1 to 1024 in 10 hours ..
