2) A kite is flying at a height of 40ft. A boy is flying it so that it is moving horizontally at the rate of 3 ft/s. The angular acceleration is 0.05rad/s² and decreasing. If the string is taut and for the instant when the length of the string is 50ft, find: a) what rate is the string being paid out, b) angular velocity, c) acceleration of the kite, d) radial acceleration. When the kite has traveled a horizontal distance of 20 additional feet it is observed to hover (not move horizontally). At this point, the \"mean\" kid of the neighborhood, who is 100feet from where the boy was standing fires his air-soft Kalash AK s740 rifle which has a muzzle velocity of 350 ft/s trying to hit the kite,. At what angle must he fire the gun in order to hit the kite? Box in your answers

(m) An investor has purchased the bottom tranche of a mortgage-backed security (MBS) consisting of 10 similar mortgages. This is the tranche that is first affected when one of the mortgages that make up the MBS defaults, and thus the investor is particularly interested in the first time T that one of the mortgages defaults. As a simplifying assumption, the investor assumes that the default times $T_1, \dots, T_{10}$ of the mortgages that make up the MBS are independent exponentially distributed with parameter $\lambda$. Then the first-to-default time is $T := \min\{T_1, \dots, T_{10}\$. By looking at historical data, the investor notes that five MBS with identical structure and characteristics had first-to-default times $T_1 = 1.2$, $T_2 = 0.9$, $T_3 = 2.1$, $T_4 = 1.5$, $T_5 = 1.3$. What is the maximum likelihood estimate estimate of $\lambda$? Round your answer to 3 decimal places. [Hint: First compute the PDF of $T$.]

10 Generalized Linear Regression In the problems of this section $x^T \beta = \beta_0 + \sum_{i=1}^p \beta_i x_i$ Problem 10.5. Y is an exponentially distributed random variable with parameter $\lambda > 0$, we write Y ~ Exp($\lambda$), if its probability density function is $f(y; \lambda) = \begin{cases} \lambda e^{-\lambda y} & y \ge 0, \\ 0 & y < 0. \end{cases}$ $\lambda$ is sometimes called the rate parameter. We want to construct a generalized linear model (exponential regression). We know that E[Y] = 1/$\lambda$, this need not be derived here. a) Find the canonical link function relating $x^T \beta$ to the mean. What does this require from $x^T \beta$? b) Write down the probability density function $f(y; x^T \beta)$. c) What is E[Y|x] in exponential regression?
