    Having some trouble with combining functions in the form y=af(k(x-d))+c

    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...

    Combining Std Dev and Mean Values

    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 =...

    Combining Phasors (Wave Forms)

    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

    Please help Im stuck with these problems ( Combining Functions)

    [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

    Phasors, combining instantaneous voltages.

    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...

    Combining Equations with different variables

    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...

    Distributive Property and Combining Like Terms.

    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.

    Calculating values when combining the tangens and cosinus function

    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...

    Combining p-adic metrics

    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...

    Combining PCA models

    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...

    Combining equations

    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...

    Combining Norms

    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...

    lim of function combining ln and trigonometry

    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}

    Combining two differential equations

    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...

    Combining equations to make one!

    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...
