Homework Help - January 2007

I don't know how to insert powers in the computer so any munber that is between a ` sign means power
OK so I have to factor polynomials, and the book explains it like this:

3k~4~-48
3k`4`-48= 3(k`4`-16)
=3(k`2`-4)(k`2`+4)
=3(k-2)(k+2)(k`2`+4) -Then it reads "k`2`+4 cannot be factored. Why not?

I want to know why, please explain in detail how to get the result of that one problem.

-Thank you

What is the best explanation for the effectiveness of insulators such as fiberglass?

2. Heat transfer is accelerated with materials such as fiberglass.

A tear drop falls,
From a new widow's eyes,
As she trys to figure out,
How she's going to live without her husband.
She can't give up, Because to her little girl,
She's now Mommy and Daddy.

As her husband fought for his life,
He thought about how they would survive,
If he were to die.
So he wrote them both letters,
Of what he thought the end might be like.

To his baby girl he wrote,
"When I die I'll go to hevean,
and over you.
The only pain I'll feel is missing you,
So please don't cry,
Just know Daddy's going to a wonderful place,
Where he'll get to meet Jesus,
Face to face.
I'll see you again someday,
But until then I'll think of you everyday."

To his wife he wrote something entirely different,
"When I die where will I go?
I seem to have lost my faith in heaven and God,
Because he's taking me away from you.
Will he be there to meet me at those pearly gates,
Or will I just wait n endless space?
My belief in God has always been storng,
But what if I've been wrong?"

Though he did not it then,
He wrote those letters in that way,
He son figured out why his mind had worked in the manner.

If he had told his little girl of his fears of death,
She might lose her faith in Him,
And might start to fear her own end.
He told his wife of them however,
Because he knew she knew God is forever.

As this new-found widow,
Read her letter,
She found her faith was stronger than ever.
She knew that God would lead her,
Through the toughest times without him,
Because her husbands last words to her were,
"I see the light that evryone speaks of,
But in my light there's something special.
God's hand is here to take me home,
Because it the end of my life here on earth,
But the beginning of the one that we will share together,
When you join me in the land of forever."
