This problem does not require the use of data mining software and focuses on knowledge of concepts and basic calculations. Sum of Withinss Over Number of Clusters (1) k=2 This problem does not require the use of data mining software and focuses on knowledge of concepts and basic calculations. Amanda Boleyn, an entrepreneur who recently sold her start-up for a multi-million-dollar sum, is looking for alternate investments for her newfound fortune. She is considering an investment in wine, similar to how some people invest in rare coins and fine art. To educate herself on the properties of fine wine, she has collected data on 13 different characteristics of 178 wines. Amanda has applied k-means clustering to this data for k = 1,...,10 and generated the following plot of total sums of squared deviations. After analyzing this plot, Amanda generates summaries for k = 2, 3, and 4. Sum of Withinss Over Number of Clusters 2000 Sum of WithinSS 1000 1500 500 Sum(WithinSS - Diff previous Sum(WithinSS 2 4 6 8 10 Number of Clusters k=2

A company purchased a bulldozer. The bulldozer was listed for $250,000. However the company was able to buy it at a $50,000 discount. The company couldn't afford to purchase the bulldozer so they paid $25,000 in cash and financed the remaining $175,000 with a five year note payable. The company also paid legal and appraisal fees of $7,500 to acquire the bulldozer and paid $25,000 to have it delivered. These extra costs were all paid with cash. What is the total capitalized cost of the bulldozer for the company on its books?

2-5. The general solution to the differential equation \frac{d^2x}{dt^2} + \omega^2x(t) = 0 is x(t) = c_1 \cos \omega t + c_2 \sin \omega t For convenience, we often write this solution in the equivalent forms or x(t) = A \sin(\omega t + \phi) x(t) = B \cos(\omega t + \psi) Show that all three of these expressions for $x(t)$ are equivalent. Derive equations for A and $\phi$ in terms of $c_1$ and $c_2$, and for B and $\psi$ in terms of $c_1$ and $c_2$. Show that all three forms of $x(t)$ oscillate with frequency $\omega/2\pi$. Hint: Use the trigonometric identities $\sin(a + \beta) = \sin a \cos \beta + \cos a \sin \beta$ and $\cos(a + \beta) = \cos a \cos \beta - \sin a \sin \beta$
