It's a 2006 Nissan Sentra SE-R Spec V. It seems like a super nice car, and the test drive was pretty good. Everything looked fine, but then I ran an Autocheck on it, and it looks like it may have some frame/unibody damage? Is this worth looking at anymore, or should I run?

They're asking $7950 for it.

Here is the autocheck report: http://goo.gl/qrQzn

What do you think?

It's a 2005 Ford Focus ZX4 SES with 138,933 miles on it. It'll be my first car, and I'm not looking for anything special. They're asking $4,495 for it.

Is this a good deal? Is this car going to start falling apart right after I buy it? I plan on taking it down to my mechanic to have him look at it first.

Thanks

I'm looking for a place where I can buy flavacol popcorn salt/flavoring in Orem or Provo, Utah. I can buy it online, but it's 2 bucks for the stuff itself, and 10 bucks for shipping.

Thanks!

There are four hidden symbols in this logo, what are they and what do they mean? I've looked, but I don't know enough about military stuff to recognized them.

Thanks!!

A 15-foot ladder is resting against the wall. The bottom is initially 10 feet away from

the wall and is being pushed towards the wall at a rate of 1

4 ft/sec. How fast is the

top of the ladder moving up the wall 12 seconds after we start pushing?

I know that I have dx/dt=-1/4 ft/sec And I know that I need dy/dt, but I can't figure out an equation to use.

Thanks!!

So my friend is going to choreograph a waltz for her ballroom class, but she needs some ideas for music.

The only idea she has so far is to have to the guys in white suits (or white pants and a white shirt) and the girls long flowing white dresses. Then she wants to put it all in black light. :D

She has two ideas for a theme. Either have the music be really creepy and the costumes be kind of tattered to look like ghosts, or have the music be such that it's like a dream.

I'm not a dancer, so don't even know where to start here...

Any ideas?

The question I have is, "Find the exact value of tan(π/3) X sin(π/2) + cos(π)"

What I did was find all the values of the trig functions then just multiply/add them.

Here're the values I have:

tan(π/3) = √3

sin(π/2) = 1

cos(π) = -1

The answer I have is: (√3)-1

Is that anywhere near right?

So I think I understand the physics just fine, I just can't solve the algebra. :D

It's the formula:

V=√[k/m(x initial² - x²)]

The data I have is:

m = .4

k = 19.6

x initial = .04

V = .14

Here is as far as I can get:

.0196=19.6/.4(0.0016 - x²)

I can't figure out how to solve for x.

Can someone help me?

Thank you!!

A container is filled to a depth of 20.0 cm with water. On top of the water floats a 30.0-cm-thick layer of oil with specific gravity 0.700. What is the absolute pressure at the bottom of the container.

I'm just stuck on this one....

Thanks!

Bone has a young's modulus of about 18 X 10^9 Pa. Under compression, it can withstand a stress of about 160 X 10^6 Pa before breaking. assume that a femur is 0.50 m long, and calculate the amount of compression this bone can withstand before breaking.

I have the answer as 1.88 X 10^5 Pa, but I have no idea how to get it.

Thanks!

So for my honors physics class, I have to build a Trebuchet that can throw a shotput at least 30m (~100 ft).

And so far, I have... nothing. We went over them in class, so I know the basic principles on how they work, but when it comes to building, I got nothing.

Detailed plans would be nice, but any information pointing me in the right direction is helpful.

Thank you!

How do you find (f○g)(x) when f(x) = 3-x/2x and g(x) = 1-2x

Thanks!

The nonuniform bar shown below is 5 meters long. It is denser near one end than near the other. It has a fixed pivot at 2.3 m from the heavy end. If the weight of the bar is 73.3 newtons and a 20 newton weight at 0.5 m from the light end will establish rotational equilibrium, what is the location of the bar's center of mass?

I'm confused here....

I know the answer is 1.7 m from the heavy end, but I have no idea how to get it. Can someone please explain this to me?

An object moves up and down the y-axis with an acceleration given as a function of time t by the expression a = A sin ωt, where A and ω are constants. What is the period of this motion?

(A) ω

(B) 2πω

(C) ω²A

(D) 2π/ω

(E) ω/2π

I'm confused. Can someone please help?

The answer is good, but it's no help without an explanation of why.

Thanks!!!

I'm doing shifted conic sections in my math class right now. I'm understanding most of it, but I'm more than a little confused when it comes to the whole completing the square thing.

Here's the problem I have, along with what I think the answers are:

Sketch the graph of the equation. Identify the vertices, foci, and asymptotes, if any.

2x²+6x+5y+10=0

Here's what I have.

It's a parabola that opens down

Vertex: (-1.5,3.875)

Focus: (-1.5,3.25)

Asymptote: n/a

If someone could first tell me if I'm right or wrong, then tell me how to do it (I think I'm wrong. :D), that would be great!

Thank you

m1v1+m2v2 = (m1+m2)v3

I know that it has something to do with the conservation of momentum, but I'm not sure exactly what.

I know this one:

m1v1i+m2v2i+=m1v1f+m2v2f

But what's that first one?

Thanks!

A 45 kg girl is standing on a 150 kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.5 m/s to the right relative to the plank.

A) what is her velocity relative to the surface of the ice?

B) What is the velocity of the plank relative to the surface of the ice?

I'm confused. I'm pretty sure I'm doing it right, yet I'm getting the wrong answer.

Here's what I'm doing:

M(girl)=45kg

M(plank)=150kg

V(girl)[initial]=0

V(plank)[initial]=0

V(girl)[final]=1.5

V(plank)[final]=?

M(girl)V(girl)[initial] + M(plank)V(plank)[initial] = M(girl)V(girl)[final] + M(plank)V(plank)[final]

So: 0 + 0 = (45)(1.50) + (150)(V)

So: 0 = 67.5 + 150(V)

So: 67.5 = -150(V)

So: V = -.45 <- Final Plank velocity.

So if the girl is moving 1.50 m/s, and the plank is moving -.45 m/s. Wouldn't her velocity relative to the ice be 1.50 - .45 = 1.05?

Book answers:

a) 1.15 m/s

b) -0.346 m/s

Does anyone know of a general chemical supply store around Utah valley? Specifically the Orem/Provo area? I'm looking for Potassium thiocyanate and I don't really want to order it online.

Thanks!

Does anyone know if there is a way to test out of any core classes in High School? English, Math, Science, etc...

I'm currently stuck in the infernal monotony and endless tedium that is the Utah education system.

Thanks!!

A 70kg diver steps off a 10m tower and drops, from rest, straight down into the water. If he comes to rest 5.0m below the surface, determine the average resistance force exerted on him by the water.

I'm pretty much bamboozled. If you could include the steps to get the answer, that would be awesome!

Thanks!
