Could someone please help me with this, I gave my answer to the teacher and did not get one right. I'm still trying to figure it out. if you could help, it would be great, thanks.

Find all the zeros of the function and write the polynomial has a product of linear factors.
1. f(x) = x^3 + 11x^2 + 39x + 29
2. g(x) = x^5 – 8x^4 + 28x^3 – 56x^2 + 64x – 32


Find a polynomial function with integer coefficients that has the given zeros
3. 0, 0, 4, 1 + i

Use the given zero to find all the zeros of the function.
4. x^3 + x^2 + 9x + 9 zero r = 3i

a) use the root or zero feature of a graphing utility to aproximate the zero's of the function accurate to three decimal places
b)determine one of the exact zeros (use synthetic division) and find the exact value of the remaining zeros.
5. f(x) = x^3 + 4x^2 + 14x + 20

1. In the spring of the year maple trees are tapped for sap to make sugar. True/False and why?
a.)True, maple trees are tapped in the spring because the sap begins to flow and the starch that was stored in the roots all winter changes back into sugar
b.)False, maple trees are not tapped in the spring because after the winter there is not enough sap to bother extracting. It must build up through the spring and summer.
c.)False, maple trees are tapped in the fall to ensure that the tree has enough energy stored to make it through the winter.

2. Potato beetles do not eat the tubers of the plant which man uses; they feed only on the leaves. Why take the trouble to poison the beetles then?
a.)Because beetle dung causes the potatoes to have a bitter flavor
b.)Because if the leaves are destroyed no photosynthesis takes place and the plant has no extra food to be stored as a potato
c.)Because the beetles burrow into the potatoes to lay their eggs

Ok, we've all seen aliens when the queen is sent out the airlock to her death. If an airlock is opened in space, what would happen? Would all the air rush out and why?

Why doesn't the same force cause our atmosphere to do the same?

What mass of aluminium oxide is produced when 54.0 g of aluminium reacts with excess oxygen?

4Al + 3O(small 2) ---> 2Al(small 2)O(small 3)

And can you please explain how you did it? I'm just trying to remember myself.

I know i've answered this question already, but i'm just so scared. I don't want to die. I mean, it is just really scary because i think about life too often, and i'm all like, omg, i'm going to die someday. Where do we go when we die? <-That's a rhetorical question, please don't answer it. My real question is: Is the world going to end? Ya know, on 12/21/12?

I am looking to rid a small amount of Lithium from the oil in which it is stored. I know that I require an organic solvent that is not water based, as it will react with the lithium. Any feedback would be great

This is the word problem:

On the moon, the acceleration due to gravity is 1.6 m/sec^2.

a) If a rock is dropped into a crevasse, how fast will it be going just before it hits bottom 30 sec. later?

b) How far below the point of release is the bottom of the crevasse?

c) If instead of being released from rest, the rock is thrown into the crevasse from the same point with a downward velocity of 4 m/sec, when will it hit the bottom and how fast will it be going?

THANK YOU SO MUCH! :]

The other night I was sleeping at my boyfriends house. He woke up to me standing over him staring at him, then I slowly started backing into his closet but continued to stare at him like I wanted him to follow me. He got up and followed me into his closet, super confused and weirded out, but I crawled through his clothes and dissapeared before he could get to me... So he's standing in his closet freaking out holding piles of clothes, and he looks back at his bed and I'm laying there asleep. He hadn't done any drugs or taken anything, and he swears he was awake... Also the ghost thing was wearing the same thing as I was wearing at the time. Any ideas on what this was? It scares me a little. Thanks.
