Captain DK

I recently read the article "The Power of Movies" by Noel Carroll to use its concepts against technological determinism. Am I on the right track? Is Carroll against technological determinism? If not, then what is his main idea that is supports?

For each of the following matrices: find its determinant, say whether or not

it’s invertible, and if so find the inverse matrix.

I already found the determinants. How would I know if or not a matrix is invertible? Can someone find the inverse matrices for the following and may be explain how they did it? Thanks a ton!

1. A=

1 2 3 4

5 6 7 8

9 10 11 12

13 14 15 16

Det (A) = 0

2. B=

13 5 2

40 15 5

0 -7 9

Det (B) = -150

3. C=

6 0

1 -19

Det (C) = -144

4. D=

2 2

-3 6

Det (D) = 18

5. E=

2 2 0

-3 6 0

0 0 1000

Det (E) = 18000

Can someone solve the following system by finding its inverse? (The inverse of this system does exist).

-4a + 3c + 34d - 4e - 34f = -5

-4a - 5b - c + 18d + 10e - 12f = 6

-3a - 2b + c + 21d + 3e - 12f = 8

5b + 5c + 21d - 12e - 10f = 9

-4a - 5b - c + 14d + 2e - 18f = -12

5a + 10b + 5c - 11e + 10f = 19

Thank you!

Whenever the marginal cost exceeds the average cost, the average cost is an increasing function. Explain why?

Thank you, I'd appreciate your help!

I don't understand the following question. So do I have to find the minimum point in the function? I can do that. But I don't understand the format the functions are written in. I'm used to the f(x)=(x^2)+5 kind of format. Can someone please help me figure out what the functions are? Thank you and I'd really appreciate your help!

For each of the following functions, determine whether or not it attains a minimum value anywhere on its domain, and if so find the minimum value and a point (on the domain) at which it is attained. Provide a brief explanation.

a) f:[-1,1]→R

x → (x^2)-1

b) g:(0,1]→R

t → t

c) h:[-6,9]→R

a → { 3 if a=2; 2 otherwise}

A skier starts down a frictionless 34{^\circ} slope. After a vertical drop of 30 {\rm m}, the slope temporarily levels out and then drops at 21{^\circ} an additional 38 {\rm m} vertically before leveling out again.

What is the skier's speed on the upper level stretch?

What is the skier's speed on the lower level stretch?

Thanks

It doesn't say "varnish" on this thing. Buh the store ppl said it was. It says: Miniwax Fast-drying Polyurethane Superior Durability Clear Gloss

Is it ok if I use this on painted plastic and hard cardboard surfaces? The paint i used was enamel.

And normally, how long does varnish take to dry on wood surface?

I understand the eye vision as +3, -5, etc.

Can anyone accurately tell what the following visions are if converted to something like +/-3.5

Distant Vision

6/9 (20/30) Corrected or uncorrected in each eye.

6/6 (20/20) both eyes

Near Vision

N5 at 30 – 50 cm

Thanks a million!

First think of the answers, then look at 'em...

Q: An elephan had a banana, but he wouldn't eat it. Why?

A: Cuz it was a plastic banana

Q: The banana was real, but he still wouldn't eat it. Why?

A: Cuz the elephant was made of plastic

Q: Both, the elephant and the banana were real, but he still wouldn't eat it. Why?

A: Cuz the banana was on TV.

Q: Both, the elephant and the banana were on TV, but he still wouldn't eat it. Why?

A: Cuz they were on different channels

Q: Both, the elephant and the banana were on the same channel, but he still wouldn't eat it. Why?

A: Cuz the TV was switched off

Q: Finally the elephant ate the banana. Why?

C’mon.. don’t be so brutal, let him eat it…

Chocolate milk or soda pop?

What out of the following is best to paint on canvas?

- Acrylic Paints

- Oil Paints

- Tempera

- Watercolors

Also, I need some helpful tips on painting.

Some info or useful links will be greatly appreciated.

Why is EDTA (ethylenediaminetetraacetic acid) used; particularly related to water hardness? And what is Chelation / chelants / chelators / chelating agents?

Please explain in terms for a grade 11 chemistry student to understand, not PhD level pls.

Also website links will be appreciated.

Thanks a lottttttt!

Can someone pls explain how the following poem relates to emotional distress, physical pain, and inferior self-esteem.

MY SOUL IS HEAVY

Reade, John

My soul is heavy with the chain

That drags me down to earth; in vain

I try to free me from its pain.

And yet I ask not wealth or fame,

I ask not power nor titled name,--

Only my Saviour's love I claim.

I fain would fix my wandering eye

Upon my treasure in the sky,

Bought by His death on Calvary.

But I am weak; my soul's best prayer

To Heaven, falls earthward, as it were

Afraid of gaining access there.

Earthward, where my soul's hopes are not;

Where I have but a pilgrim's lot:

Why is my Father's home forgot?

Earth's fairest scenes must pass away,

Man's mightiest monuments decay,

And the poor traveller may not stay.

O Comforter Divine, appear,

Impart the love that knows not fear,

And let me feel Thee ever near.

Then shall my soul, form earthly things

Set free, soar up on tireless wings,

To where God's choir for ever sings.

Is there an audiobook version of the novel Crow Lake; the author is Mary Lawson.

Is there a software that converts letters into notes?

For example: If I type something like:

C D D# D C, A#-C D C A#-, G#-A#-C A#-G#-

I want it to be converted to notes on a 5 line staff. Is there a website or program that does this?

Pls don't tell me how its converted manually, I know that; but I have tons of it to convert, so I need a software or program that does it.

Thanks

pls don't say look for some software online. specify which software; cuz i downloaded several of em and they don't work.

Theres this chemistry assignment, I've to make a presentation describing a practicle application of a concept covered in one of the following:

1. Matter and Chemical bonding

2. Chemical Quantities

3. Solutions and Solubility

4. Gases and atmospheric chemistry

5. Hydrocarbons and Energy

What I need now is, a suggestion on a very interesting topic that relates to one of the above concepts. Or some new inventions/innovations, etc. that I could present on. Or a website that has cool and RECENT chemistry news.

P.S.: please post ur sources.
