The controller of Brandon Co has requested a quick estimate of the manufacturing supplies needed for August when production is expected to be 480,000 units. Below are actual data from the prior four months of operations: Production in units Manufacturing supplies March 425,000 $700,120 April 500,000 $840,250 May 475,000 $824,770 June 415,000 $705,950 Using these data and the high-low method, what is the best estimate of the cost of manufacturing supplies that would be needed for August? (Assume that this activity is within the relevant range.)

3. Compton Scattering An incoming high-energy Xray exits a Compton scattering event with a longer wavelength, after ejecting an electron from a metal foil: (a) Explain in detail, including all of the relevant equations and conservation principles, why the outgoing Xray will have a longer wavelength in this case. (b) --- If the ejected electron is travelling at a speed given by $\beta$ = 0.1250, what is its kinetic energy? Are special relativistic formulas required to calculate this kinetic energy? Explain why or why not, and then solve for the electron's kinetic energy in the appropriate manner. [ rest mass of electron = $m_0$ = 9.109 x $10^{-31}$ kg] (c) --- If the incoming Xray has a wavelength of 0.2327 nm, what is the outgoing Xray's frequency? (d) --- If the electron was ejected at an angle of 9.678° above the straight-through position, at what angle would the outgoing Xray have to travel? Explicitly state any conservation principles you may need to use. Include a well-labelled physics-relevant diagram to help support your calculations.

Let $x(t) = \sin (10\pi t)$ be a signal to be sampled, processed as a discrete-time signal, and\nconverted back to continuous-time. Model the sampled signal as\n$x_s(t) = x(t)p(t)$,\nwhere the sampling function, with sampling interval $T_s = 0.125$, is an impulse train:\n$p(t) = \sum_{n=-\infty}^{\infty} \delta(t - nT_s)$.\nThen the sampled signal is converted back to continuous-time through a reconstruction filter:\n$x_R(t) = x_s(t) * h_R(t)$.\nThe reconstruction filter cuts off at half the sampling frequency and has frequency response\n$\tilde{H}_R(\omega) = T_s \text{rect}\left(\frac{\omega}{\omega_s}\right)$.\nSketch the magnitude spectra of the following signals:\na. The input signal: $x(t)$\nb. The sampled signal: $x_s(t)$\nc. The reconstructed signal: $x_R(t)$
