Question

Medal and fan!!!!!
A culture started with 2,000 bacteria. After 8 hours, it grew to 2,400 bacteria. Predict how much bacteria will be present after 19 hours. Round answer to the nearest whole number.

Answer 1

Because the bacteria culture grew by 200 bacteria in 6 hours, the unit rate of that is 33 1/3 bacteria growing per hour. If you multiply that by 12, you get 400.

If you add 2,000 + 400 = 2,400 bacteria growing

Answer 5

im pretty sure lol

Answer 6

First we solve for the rate
k = (ln [y(t) ÷ a]) ÷ t
where y(t) is ending amount
a is beginning amount
t is time
k = (ln (2400/2000)) / 8
k = (ln (6/5)) / 8
k = ln(1.2) / 8
k = 0.18232155679 / 8
k = 0.0227901946

y(t) = a × e k*t
endg amt = 2,000 x 2.718281828^(0.0227901946 * 19)
endg amt = 2,000 x 2.718281828^0.4330136974
endg amt = 2,000 x 1.5418973404
endg amt = 3,084
