In Claudia’s investigations, she prefers to use DNA evidence whenever she can. Why is this MOST likely to be her preference?
IrinaVladis [17]
DNA evidence is the most concrete and reliable. It is far better than options and untrustworthy evidence.

Answer:

x^2\neq -\frac{5}{13}

First option

Explanation:

<u>Operations with functions </u>

Given two functions f, g, we can perform a number of operations with them including addition, subtraction, product, division, composition, and many others .

We have

f(x)=20x^3-7x^2+3x-7

g(x)=-13x^2-5

We are required to find

\displaystyle \frac{f}{g}(x)

We simply divide f by g as follows

\displaystyle \frac{f}{g}(x)=\frac{20x^3-7x^2+3x-7}{-13x^2-5}

We know rational functions may have problems if the denominator can be zero for some values of x. We must find out if there are such values and exclude them from the domain of the new-found function. We must ensure

-13x^2-5\neq 0

or equivalently

x^2\neq -\frac{5}{13}

Thus the first option is correct

Note: Since x^2 is always a positive number (for x real), our function does not really have any restriction in its domain

Answer:

have you ever feel like a plastic bag

Explanation:

Do you ever feel like a plastic bag

Drifting through the wind

Wanting to start again?

Do you ever feel, feel so paper-thin

Like a house of cards, one blow from caving in?

Do you ever feel already buried deep

Six feet under screams but no one seems to hear a thing

Do you know that there's still a chance for you

'Cause there's a spark in you?

You just gotta ignite the light and let it shine

Just own the night like the 4th of July

'Cause, baby, you're a firework

Come on, show 'em what you're worth

Make 'em go, "Ah, ah, ah"

As you shoot across the sky

Baby, you're a firework

Come on, let your colors burst

Make 'em go, "Ah, ah, ah"

You're gonna leave 'em all in awe, awe, awe

You don't have to feel like a wasted space

You're original, cannot be replaced

If you only knew what the future holds

After a hurricane comes a rainbow

Maybe a reason why all the doors are closed

So you could open one that leads you to the perfect road

Like a lightning bolt your heart will glow

And when it's time you'll know

You just gotta ignite the light and let it shine

Just own the night like the 4th of July

'Cause, baby, you're a firework

Come on, show 'em what you're worth

Make 'em go, "Ah, ah, ah"

As you shoot across the sky

Baby, you're a firework

Come on, let your colors burst

Make 'em go, "Ah, ah, ah"

You're gonna leave 'em all in awe, awe, awe

Boom, boom, boom

Even brighter than the moon, moon, moon

It's always been inside of you, you, you

And now it's time to let it through, -ough, -ough

'Cause, baby, you're a firework

Come on, show 'em what you're worth

Make 'em go, "Ah, ah, ah"

As you shoot across the sky

Baby, you're a firework

Come on, let your colors burst

Make 'em go, "Ah, ah, ah"

Boom, boom, boom
