Problem1 The behavior of a physical system can be described by the following first order differential equation: dy/dt=2y +t^2

daser333 [38]

Answer:

$y = \dfrac{t^3e^{2t}}{3}+Ce^{2t}$ .

Step-by-step explanation:

Using first order linear differential equation:

$\dfrac{\mathrm{d} y}{\mathrm{d} t} = 2y + t^2$

$\frac{\mathrm{d} y}{\mathrm{d} t} - 2y =t^2$

finding integrating factor:

I.F = $e^{\int -2dt}$

I.F = $e^{-2t}$

now,

$y = \dfrac{1}{IF}(\int t^2dt+ c )$

$y = \dfrac{1}{e^{-2t}}(\int t^2dt+ c )$

$y = \dfrac{t^3e^{2t}}{3}+Ce^{2t}$

hence the solution is

$y = \dfrac{t^3e^{2t}}{3}+Ce^{2t}$

Orlov [11]

Answer: Her weekly allowance is 24 dollars

Step-by-step explanation:

If she is left with $12 spending half of her weekly allowance the we could set up the equation.

1/2 of x = 12 where x is her weekly allowance.

1/2x = 12

x = 24

If Sam would like to see only the records that have a price that is more than ten and a profit that is more than three percent,

Misha Larkins [42]

Hello :)

I think this answer is third because you said "more than 10" and this is meaning :

>10

then you said "more than three percent" and this is meaning :

> %3

My answer is = > 10 and > 3%

Have a nice day :)

What is the end behavior of the function f of x equals 3 times the cube root of x? as x → –[infinity], f(x) → –[infinity], and a

geniusboy [140]

The function $f(x)=4\sqrt[3]{x}$ is a cube root function and the function end behavior is: $x$ → $+$ ∞, $f(x)$ → $+$ ∞, and as $x$ → - ∞, $f(x)$ → $+$ ∞

<h3>What is end behavior?</h3>

The end behavior of a function f defines the behavior of the function's graph at the "ends" of the x-axis.
In other words, the end behavior of a function explains the graph's trend when we look at the right end of the x-axis (as x approaches +) and the left end of the x-axis (as x approaches ).

To determine the end behavior:

The equation of the function is given as: $f(x)=4\sqrt[3]{x}$
To determine the end behavior, we plot the graph of the function f(x).
We can see from the accompanying graph of the function:
As x approaches infinity, so does the function f(x), and vice versa.
As a result, the function end behavior is:

$x$ → $+$ ∞, $f(x)$ → $+$ ∞, and as $x$ → - ∞, $f(x)$ → $+$ ∞

Therefore, the function $f(x)=4\sqrt[3]{x}$ is a cube root function and the function end behavior is: $x$ → $+$ ∞, $f(x)$ → $+$ ∞, and as $x$ → - ∞, $f(x)$ → $+$ ∞

The complete question is given below:

What is the end behavior of the function f of x equals negative 4 times the cube root of x?

As x → –∞, f(x) → –∞, and as x → ∞, f(x) → ∞.

As x → –∞, f(x) → ∞, and as x → ∞, f(x) → –∞.

As x → –∞, f(x) → 0, and as x → ∞, f(x) → 0.

As x → 0, f(x) → –∞, and as x → ∞, f(x) → 0.
