Question

Leah is studying a bacteria sample that increases 4 times in mass every day. At the end of day 1 of her study, the sample has a mass of 4 milligrams. What is the mass of the bacteria sample after 6 days of study? Write each expression in the correct column of the table.

PLEASE HELP SERIOUSLY!! 8th grade math

Answer 1

after 6 days equation would be and answer

`4^6 = 4096`
to represent before 6 days just put 4^5=1024

Answer 2

Explanation:

Given that Leah is studying a bacteria sample that increases 4 times in mass every day.

Let m(t) represent the mass after t days,

Given that
`m(1) = 4`

Hence initial mass
`= m(0) = (4)/(4) =1`

The general equation for m(t) would be

`m(t) = 4^t\\`

Hence after 6 days the mass of the bacteria

`=4^6\\=4096` gm
