For some reason, this isn't working out. The Arhennius equation, k = A*e^(-Ea/RT) I have tables of temperature and k. The book says just calculate it by having the x-axis be 1/T and y-axis be ln(k) Ok, take Ln of both sides ln(k) = ln(A*e^(-Ea/RT)) ln(k) = -Ea/RT + ln(A) Oh, that...

I wrote down the notes from class, but when I tried to do the homework, I am not even close to the right answers. The formula I wrote down is: \frac{-1}{(x)(x+h)} Apparently that's wrong. Anyone know what it's supposed to be?

:smile: My question says f(x)=(-5/7)x-3 determine the slope of f^-1(x) without finding the inverse. I think the answer is the slope of f^-1(x)=(-7/5)x Is this correct?

Hey ppl, If you have a man pushing a box up a slope with a horizontal force at constant speed from distance a to b, can one assume the Work done by friction to be zero all the time since velocity is constant? or can one assume W(neoconservative)=change in U(gravitational PE) only, with...

I'm new at this, so I hope someone can help me. I have AP Calculus and need some help on a problem... Given the curve x+xy+2y^2 = 6 Find the coordinates of all points on this curve with slope equal to the slope at (2,1) Any help is much appreciated!

I got this problem for physics and i can't seem to get it, it goes like: A projectile is launched at an angel of 40 degrees with an initial velocity of 100 m/s. One hundred meters away is the beginning of a hill that slopes upward at an angle of 20 degrees. The projectile strikes the hill a...

A football is kicked into the air at some angle theta and lands down field. Ignoring air friction, draw a rough plot of its speed versus time. Is the slope of the curve the acceleration? Explain. I think the slope of the curve is the absolute value or the magnitude of acceleration, isn't it?

I'm still having trouble with figuring out slope fields. If I have a function dy/dt= f(t,y), how would I go about graphing the slope field for my solutions without the use of a calculator. An example would be how would I graph the slope field of dy/dt = t^2-t and dy/dt = y^2? Thanks.

I always thought the M stood for something like meta which was like greek for change or something.. but I am not sure that is right =-/ Can someone also refresh my memory regarding the meaning of b in the y intercept fomula?.. why did they decide to set it to be.. I think there is a reason...

2. Two mountains are at elevations of 850m and 750m above the valley between them. A ski run extends from the top of the higher peak to the top of the lower one, with a total length of 3.2km and an average slope of 30 degrees, a) A skier starts from rest on the higher peak. At what speed will...

hey firstly, I am not so certain this is the correct place for this thread, sorry!feel free to move! basically, if you look at the file attached, I am trying to find friction up the slope, but i cannot do it, and i can't see how you will do it, so if anyone could shine some light, i would be...

A boy is traveling down a slope on a sledge. The boy and the sledge have a total mass of 60kg and are traveling at a constant speed. The angle of the slope to the horizontal is 35 degrees. There are 3 forces acting on him, the weight of him and the sledge acting straight down W, the push from...

19) An Olympic skier moving at 20m/s down a 30degree slope encounters a region of wet snow, of coefficient of friction, .74 a. How far down the slope does he go before stopping? I know the answer is 144m, but how do I get there? b. How much mechanical energy is lost in this process...

What do you do to find the x and y coordinates of a ball that is thrown from a building onto a slope? *Initial velocity is given along with the angle *The height of the building is given *And the angle of the sloped ground is given

how to find the slope? ok, I'm really confused with this Question: "Whats the slope of a 0 degree angle, and if so how did u do it or how can u prove it. I need a reply because it is urgent. thanks for replying:smile:

[SOLVED] Tractor up a slope The question is as follow... A farm tractor tows a 4300kgs trailer up an incline 26 degrees aboe the horizontal at a steady speed of 3.0m/s. What force does the the tractor exert on the trailer? I've read the section over in which this problem is included in...

umm... I'm not really used to using forums.. but whoever is online now and reading this... i would reaLLY appreciate if you could help me on this question.. this is fairly uRGent because its a bonus question which i want to hand in early tomorrow. i've already spent a lot of time on it.. and...

Hi, I was looking at a problem from an old test and I got confused about something. Q. Find the slope of the tangent line to the given curve at a given point: y = x(x^2 + 3)^1/2 ; P(1,2) S. First I found the derivative: [(x^2 + 3)^1/2] + [(x^2)(x^2 + 3)^-1/2] Plugged in the...

I just don't get it! We're learning about finding the slope of a line. And I don't get any of it, so can someone explain it to me? I could find the slope through a pair of points: C->1(2,1) 1-1 =0 D->2(3,1) 2-3 =-1 and the answer is 0...(note that this is algebra((or...
