Consider the given statement. At least one gift in the bag is wrapped.

jasenka [17]

Answer:

The negation to the given statement "At least one gift in the bag is wrapped - true" is " At least one gift in the bag is not wrapped" - False

At least one gift in the bag is not wrapped - False
Not every gift in the bag is wrapped-True
Every gift in the bag is wrapped-False
None of the gifts in the bag are wrapped-False

Step-by-step explanation:

Given statement is At least one gift in the bag is wrapped is true

The negation to the given statement is " At least one gift in the bag is not wrapped" - False

<u>To determine whether the statement is a negation of the given statement is True or False :</u>

<h3> At least one gift in the bag is not wrapped - False </h3><h3> Not every gift in the bag is wrapped-True </h3><h3>Every gift in the bag is wrapped-False </h3><h3>None of the gifts in the bag are wrapped-False</h3>

Tonya is saving money to buy a computer that costs $375. She has saved $75 already and each week she adds $25 to her savings. Ho

schepotkina [342]

It will take her 12 weeks if she saves the money she gets per week
Since the price of the computer is $375 and she already has $75 dollars saved she only needs $300 more to buy the computer.
She gets $25 per week so she it will take (25/300) weeks for to buy the computer
so that simplifies into 12 weeks
therefore it will take her 12 weeks to buy her computer

Find the general solution of the given differential equation.

Elina [12.6K]

Answer:

$y=-x\,cos\,x+Cx$

There are no transient terms.

Step-by-step explanation:

Given: $x\,\frac{dy}{dx} -y=x^2\,sin\,x$

To find: general solution of the differential equation and the transient terms in the general solution.

Solution:

For an equation of the form $\frac{dy}{dx}+yp(x)=q(x)$ ,

solution is given by $ye^{\int {p(x)} \, dx }$ = ∫ q(x) $e^{\int {p(x)} \, dx }$ dx

The given equation $x\,\frac{dy}{dx} -y=x^2\,sin\,x$ can be written as $\frac{dy}{dx}-\frac{y}{x}=x\,sin\,x$

Here,

$p(x)=\frac{-1}{x}\,,\,q(x)=x\,sin\,x$

$e^{\int{p(x)} \, dx } =e^{\int{\frac{-1}{x} } \, dx } =e^{-ln(x)} =e^{ln(x^{-1} )}=x^{-1}=\frac{1}{x}$

So,

the solution is $\frac{y}{x}=\int \frac{1}{x}x\,sin\,x\,dx$

$\frac{y}{x} =\int\,sin\,x\,dx\\\\\frac{y}{x} =-cos\,x+C\\y=-x\,cos\,x+Cx$

Here, C is a constant.

Transient term is a term such that it tends to 0 as x → ∞

Here, there does not exist any term that tends to 0 as x → ∞

So, there are no transient terms.
