combining

Hi, This is my first attempt at getting some help on this website so I apologize if I did anything incorrectly. I recently started MRC3U Grade 11 University Prep Functions through an ILC course, and I've come across a question that has me stumped. We have to describe the transformations that...

I'm wondering if there is a way to combine the data for Machine A and Machine B in the problem below to come up with one data set, i.e. 1 std deviation value and 1 mean value for Machine A and Machine B combined. I was thinking I could just add the mean/std deviation values and get mean =...

The instantaneous values of two alternating voltages are given by: v1= 150sin(ωt+ π/3) Volt v2= 90sin(ωt- π/6) Volts Derive a sinusoidal expression-resultant v1+ v2 in form Rsin(ωt+ α) Combine the phasors (Vectors) of each wave form? Thanks in advance

[COLOR=#333333][FONT=verdana]1) Cell phones begin to lose (resale) value immediately after purchase. After one year, an iPhone can be resold at 63% of its list price. Assume that each year after that, the resale value continues to drop to 63% of the resale price from the

If the Instantaneous value of two voltages are: V1= 80 Sin (wt + π/3) V2= 50 Sin (wt - π/6) Find the sinusoidal expression for V1 + V2. I understand that you need to draw a phasor diagram, then calculate the magnitude of resistance using the vertical and horizontal components. But every time...

I have an equation showing how the failure load changes with respect to variable A when variable B is fixed. I also have an equation showing how the failure load changes with respect to variable B when variable A is fixed. How do I combine them so that I can see what the failure load is at...

HI everyone. I really need help with this question. When i use a math solver it doesnt show me the steps and I need this question answered it is just too hard for me so if anyone can help that would be great. Simplify the Expression 3x + 4(3 + 5x) + 2(4x - 3). Identify the properties you used.

Hello, I'm currently studying for an exam I will have right before semester 2 starts now in August and I could really use some help The question is basically "Calculate the value of tan(cos^-1(0.5))" I can't understand why or how I would do this, do I turn cosinus into something using sinus...

Let p,q be two prime numbers. Define d:\mathbb{Q} \times \mathbb{Q} \to [0,\infty) by d(x,y) = \max\{|x-y|_p,|x-y|_q\}. Is there an algebraic analogue to the completion of the rationals by this metric similar to the inverse limit of \Bbb{Z}/p^n\Bbb{Z} for the completion of the rationals by a...

Hello, I am working with face recognition. I have two models from two separate datasets with the same number of dimensions. I wish to implement this method to combine PCA models. http://www.cs.cf.ac.uk/Dave/Papers/Pami-EIgenspace.pdf My linear algebra isn't great. So i am lost after step 1...

Hello, I am building an active appearance model. I have a large training data set. Too big. :/ My computer's RAM cannot handle a model of this size. If i make a series of smaller PCA models. Is there a way to combine a series of PCA models into one 'averaged' projection space? Each sample is...

Hi, I have two equations that I need to combine to find the value of a variable. My tutor has been through this but I don't get it. Please could you walk me through the steps? I have 1)Vr = Vm/FCR and 2)VL = Vm-Vr/2 and I need to solve for Vm by substituting equation 1 into equation 2. The...

The p-adic norms are all of the possible norms on the rationals (any other norm is equivalent to one of the p-adic norms, where p is prime or infinity). Given two norms on a space (say the p-adic and q-adic norms), is there a way to combine them? For example, given r \in \mathbb{Q}, would...

I have this situation can I combine the following terms DDDa = |d1-a1-p1/C|+|d1-a1-(p1+p2)/C|+|d1-a1-(p1+p2+p3)/C| Thanks Ian

is there a method (arithmetic simplification or something) which with i can solve lim that combine ln, e, and trigonometry? for example: lim_{x\rightarrow0}\frac{ln(cosx)}{cosx-1} and: lim_{x\rightarrow\infty}\frac{2x-sin2x}{x^{2}+cos^{^{2}}x}

Two quantities, x and y, vary with time t. State the differential equation for each of the following. (a) The rate of change of y with respect to t varies inversely as x. (b) The rate of change of x with respect to t varies inversely as y. Combining the differential equation of (a) and (b), form...

Hi everyone can anyone help me understand how to merge two Poisson processes lets say λ1 and λ2 and how it can produce a new process with rate λ1+λ2. Thanks in advance. Regards

Need some help with this. Not understanding my notes on the lecture. Simplify the following by combining all terms into a single logarithm. ln(x^2)+(1/3)ln(x-2)-4 Thanks to anyone who helps.

Howdy! I have a set of 8 objects: {A, B, C, D, E, F, G, H} I have 6 buckets. I must place all 8 objects in any combination of the 6 buckets. I can place between 0 and 4 objects in any bucket. I must place all objects in a bucket. A and B cannot be placed in the same bucket. C and D cannot...

Hello this question is based on a transfer function problem and I have the following formulas and need to arrive at an equation for T/VD in terms of k0, k1, k2 and kt where E = VD - VM, I = Ek1, T = k0I, Vt = ktT and Vm = k2Vt My attempt: T = k0I where I = Ek1 therefore T = k0Ek1 where E...
