A solution initially contains 200 bacteria. 1. Assuming the number y increases at a rate proportional to the number present, wri
GuDViN [60]

Answer:

1.\frac{dy}{dt}=ky

2.543.6

Step-by-step explanation:

We are given that

y(0)=200

Let y be the number of bacteria at any time

\frac{dy}{dt}=Number of bacteria per unit time

\frac{dy}{dt}\proportional y

\frac{dy}{dt}=ky

Where k=Proportionality constant

2.\frac{dy}{y}=kdt,y'(0)=100

Integrating on both sides then, we get

lny=kt+C

We have y(0)=200

Substitute the values then , we get

ln 200=k(0)+C

C=ln 200

Substitute the value of C then we get

ln y=kt+ln 200

ln y-ln200=kt

ln\frac{y}{200}=kt

\frac{y}{200}=e^{kt}

y=200e^{kt}

Differentiate w.r.t

y'=200ke^{kt}

Substitute the given condition then, we get

100=200ke^{0}=200 \;because \;e^0=1

k=\frac{100}{200}=\frac{1}{2}

y=200e^{\frac{t}{2}}

Substitute t=2

Then, we get y=200e^{\frac{2}{2}}=200e

y=200(2.718)=543.6=543.6

e=2.718

Hence, the number of bacteria after 2 hours=543.6

A rotation is a transformation where an object move
ICE Princess25 [194]

Let's rephrase this:

Here:

There are 3 geometric transformations:

1. Rotation

Shapes are rotated or turned around an axis.

2. Reflection

Shapes are flipped across an imaginary line to make mirror images.

3. Translation

Shapes are slid across the plane.

Which statement best defines the two quantities that are measured to find the rate at which an airplane descends? A) The quantit
Schach [20]

The <em>correct answer</em> is:


C) The quantity of distance measured in feet depends on the quantity of time measured in minutes.


Explanation:


The rate of an airplane's descent would be found using the distance it descends and the amount of time that takes.


In this situation, the amount of time that passes causes the distance the plane descends to change; this means that the distance depends on the time.
