k I've been reading and it seems as though what I'm dealing with is a common mean rather than a weighted mean I'm dealing with slope figures of a v(t) graph and trying to find g avg +- delta g avg as to compare it with my theoretical results the values I gave above were ambigous but the...

Homework Statement Quick question, working on a lab Just wondering how I could go about getting an average value for a series of figures with +- values. For instance 1) 1.5 ± 0.02 2) 1.7 ± 0.84 3) 1.7 ± 0.08 The Attempt at a Solution I tried enclosing the figures within...

Homework Statement This is just a question regarding error calculation in physics labs. I've never before in my career as a student done any lab work, this is a 1st year undergraduate physics course. For this lab we were required to create an experiment that would illustrate acceleration...

I've been using my calculator to graph a few functions. When I go the plot function menu and add a new function at this point [Y7(X)=] will appear. If I press [Choos] I will be able to select previous functions that I have entered and graphed. I want to erase these functions, so that when I...

Homework Statement A police ar traveling a constant 90 km/h is passed by a speeder travelig 130 km/h. 1.00s after the speeder passes, the policeman steps on the accelerator. If the police car's acceleration is 2.00 m/s^2, how much time elapses after the police car is passed until it...

Homework Statement Find the inverse of each function. Is the inverse a function or a relation ? f(x) = (x-4)/3 The Attempt at a Solution Not sure which one is correct, and if any are not sure why (as in rules that may apply) f(x) = (x-4)/3 f^-1(x) = 3x+4 or f^-1 3x+12

You give up before you try, you are failure.

necessity without doubt both because humanity for the most part is made up of many stupid people, and that necessity is the mother of invention.

Humans today are in a race for their very survival. It is essential that each generation work towards it's full potential as to aid the development of space travel and colonization. It's in our DNA, our primary function is to survive. So at some point that will become the absolute...

Thanks man, I didn't know that law of sines can give you two solutions, we just started our trig unit last class. So just to be sure, for future assignments or whatever, I would work out the question like this. Sin C/c = Sin B/b Sin 10.5/25 = Sin B/66 (66)Sin10.5/25 = Sin B...

Homework Statement I have to find the measures of the angles x & y. Homework Equations Sine Law Cosine Law The Attempt at a Solution First thing I tried to do was find the measure of the angle @ A. a/SinA = c/SinC 66/SinA = 25/Sin10.5 and then I end up with 28...

yeah, that's what I've been doing for devices I have listed that run longer than an hour for example our washing machine 1200W - 210 minutes @ 4 days per month 1.2kW x 3.5h = 4.2 kWh 4.2kWh x 31 days = 130.2 kWh/month

Homework Statement The question asks for us to go around our house, figure out the power usage of different devices, based on the estimated time use of these devices and calculate the total power usage per month. Homework Equations Energy = Power X Time Power = kW Time = hours...

most of the stuff at best buy is marked up as high as 400% you're buying it for a lot cheaper on "black friday" but you're still getting ripped off you can get these "amazing" prices at tiger direct any day of the year

Trying way too hard.
