Se ha determinado que la población P (t) de una colonia de bacterias, t horas después de iniciar la observación, tiene una razón

maxonik [38]

Answer:

La población 20 horas después será de 321,161 bacterias.

Step-by-step explanation:

t horas después de iniciar la observación, tiene una razón de cambio de P'(t) = 350 e0.18t + 220 e-0.3t.

Esto implica que la población después de t horas viene dada por:

$P(t) = \int P^{\prime}(t) dt$

$P(t) = \int (350e^{0.18t} + 220e^{-0.3t}) dt$

Teniendo en cuenta que

$\int e^{at} dt = \frac{1}{a}e^{at}$

$P(t) = \int (350e^{0.18t} + 220e^{-0.3t}) dt$

$P(t) = \frac{350}{0.18}e^{0.18t} - \frac{220}{0.3}e^{-0.3t} + K$

En que k es la población inicial, o sea, $K = 250000$ . Entonces

$P(t) = 1944.44e^{0.18t} -733.33e^{-0.3t} + 250000$

¿Cuál será la población 20 horas después?

Esto eres P(20). Entonces:

$P(20) = 1944.44e^{0.18*20} -733.33e^{-0.3*20} + 250000 = 321161$

La población 20 horas después será de 321,161 bacterias.

Two cars started at the same time, from the same point, driving along the same road. The rate of the first car is 50 mph and the

Roman55 [17]

See my attached picture.
Remember that distance is speed*time, d = s*t.
$d_{1} = s_{1}t = 50 \frac{mi}{h} * t \\ 
d_{2} = s_{2}t = 30\frac{mi}{h} * t \\$

The distance for both cars total is 30. As a formula, this is
$d_{1} + d_{2} = 30$ .

Putting the formulas together,
$50t + 30t =30 \\ 80t = 30 \\ t = 3/8$
The time it takes is 3/8 hours.
