I need to double check these answers before I submit them.

1.) A car is traveling to the right, which we will consider to be the positive direction, at a speed of 10.0 m/s. Over a distance of 4.0m, the car slows to a speed of 2.0 m/s. What is the average acceleration of the car?

>I don't think I can get the answer from the information given...

2.)An object is moving to the right in a straight line. The net force acting on the object is also directed to the right, but the magnitude of the force is decreasing with time, but is always present and always points to the right. The object will...

> I thought that the object would continue to move to the right, with its speed increasing with time

She's a witch... No to mention racist, deluded, and overly self entitled. I consider myself a gentle person, but I want nothing more than to kill her. I want to make her suffer and bleed and cry for mercy for what she's done to me. She's abusive in many ways, and I've never completely told anybody else about what she's been doing, not even my brother, who's gone to college, my dad, who's never home, or my closest friends. Nobody knows, and I just wanted to rant anonymously online.

She always hits me when nobody's around- I'll say something non offensive, but she becomes extremely angry and starts screaming at me. She calls me useless, stupid, immature, ugly, fat, and brainwashed. I stopped taking her insults, though. I talk back. It only makes things worse.

Just a few minutes ago, another fight broke out. She smacked and bullied me. I did not hit her back- never have. She locked me in the garage, and I'm literally bawling my eyes out. I don't want live like this.

what is the derivative of e^(5ln(x^3))? I keep getting (15/x)e^(5ln(x^3) which is wrong.

I'm a full blooded Vietnamese girl, who's fluent in Spanish and English. However, I want to learn one of the for mentioned languages... It's just that ,'m hesitant to pick which one.

I have reasons for each, as well as reasons against each...

Vietnamese- - I'm Vietnamese, I can speak a bit of the language but can't read or write, my parents encourage this but refuse to help. However my interest in Vietnamese culture is limited.

Korean-- my boyfriend is Korean (but its not like we're serious or anything), I already know the alphabet and limited vocabulary, I'm into Korean fashion, history, and customs as well as the cuisine and aesthetically pleasing koreans... I listen to a lot of Korean music, and occasionally watch Korean movies with subtitles. Many of my friends are also Korean or submersed within its culture, and I should also mention that I often shop in Korean stores and read Korean many was and such. However my parents are racist and discourage this.

Japanese - - because I'm a nerd. I watch anime, read manga, and play lots of video games, the majority of them being Japanese. (It's kind of a closet hobby, because otherwise I seem like a fairly normal girl. I don't really express my love for this stuff). I program small scale video games in my spare time, and want to translate them into Japanese to gain a larger audience. Several of my friends are also Japanese, and I'm also interested in Japan's fashion and mainstream culture, as well as visual kel and other theatrical aspects. And again, my parents don't like Japanese people, and discourage this because they're racist.

But what can they do about it, anyway?

sin4x/cos2x

Well, I tried it and got 1/2, which is an available answer, but I'm too cautious to try it out just yet.

Here's my work.

2sin2xcos2x/cos2x

2sin2x

1/2(2)(-cos2x)

-cos2x

-cos(pi/3) - (-cos(0))

-cos(pi/3) + cos(0)

-.5 + 1

=.5

HELP MEH.

I keep gettin 7.181356. it's wrong.

wo..man?

Anybody know about this?

I'm looking through some webpages and my book right now, but I need all the information that I can get.

and the square of the other number

will be a maximum.

10 and 10, right?

Make the following assumptions:

1) The density of liquid water at 100C is 1.00

g/mL;

2) the vapor is adequately described by the

ideal gas equation;

3) the external pressure is constant at 1.00

atm; and

4) the heat of vaporization of water is 2.26

kJ/g.

What is q for the vaporization of 1.00 g of

liquid water at 1.00 atm and 100C, to the

formation of 1.00 g of steam at 1.00 atm and

100C?

I tried using q=mcT but since there is no change in temperature, I always get 0. It's in the list of possible answers, but I'm seriously doubting myself. Phuk it.

Are there any equations or something I need to know for this? I'm thinking q = mcT, but I'm not so sure how to go about this.

For example, what should I do in:

The enthalpy of combustion of benzoic acid

(C6H5COOH) which is often used to calibrate

calorimeters, is −3227 kJ/mol. When 1.303 g

of benzoic acid was burned in a calorimeter,

the temperature increased by 2.054C. What

is the overall heat capacity of the calorime-

ter? The overall heat capacity includes the

calorimeter hardware and the water that is in

it.

Answer in units of kJ/C

Carbon monoxide reacts with oxygen to form

carbon dioxide by the following reaction:

2CO(g) + O2(g) ---> 2CO2(g)

H for this reaction is −566 kJ/mol rxn.

What is the
H for CO(g)?

Noooo idea how to do this!

((sin (pi/6) +h ) - (1/2)) / h

The closest I'm getting is xcosx + x^2sinx

I've been using product rule. Meh.

Their sleep was deep—deeper than any which the white man knows, —a sleep from which they were never to awaken.

My teacher is worthless... it's been like 5 weeks and he hasn't taught us anything. He gave us 3 problems, and I know I have to plug the values into an equation to find the answer... but He never gave us a book OR a reference sheet so I don't even know what I'm supposed to do. And the homework is worth a text grade apparently... I really need help with this.

A passenger in a helicopter traveling upwards at 22 m/s accidentally drops a package out the window. If it takes 21 seconds to reach the ground, how high to the nearest meter was the helicopter when the package was dropped?

8

To the nearest meter what was the maximum height of the package above the ground in the previous problem?

A speeder traveling at 48 m/s passes a motorcycle policeman at rest at the side of the road. The policeman accelerates at 3.07 m/s2. To the nearest tenth of a second how long does it take the policeman to catch the speeder?

If the function f is continuous everywhere

and

f(x) = x^2−9 / x+3

when x =/= −3, find the value of f(−3)

I think the answer's -6, but I'm not completely sure.

-----------------------

Determine if

lim

h-->0

f(1 + h) − f(1) / h

exists when f(x) = x2 − 3x, and if it does,

find its value.

i have a vague guess of what I should do, but... meh..

f(x) = (cos x + 3 sin x)2

from the corners then folding up the sides.

Theres a little picture of a rectangle, where the corners have squares that are 6 inches in length. The area in between the squares on one side is 2x+9, the other is just x.

How do I solve for the width of the original piece of metal?
