5. Find the Taylor series for $f(x)$ centered at the given value of $a$, and find the radius of convergence. [Assume $f$ has a series expansion at $a$. Don't show $R_n(x)\rightarrow 0$.] a) $f(x) = x^5 + 2x^3 + x$, $a = 2$ b) $f(x) = 1/x$, $a = -3$ c) $f(x) = \frac{1}{\sqrt{x}}$, $a = 1$ Hint: $1 \cdot 3 \cdot 5 \cdots (2n + 1) = \frac{1 \cdot 2 \cdot 3 \cdots (2n + 1)}{2 \cdot 4 \cdot 6 \cdots (2n)} = \frac{(2n + 1)!}{2^n n!}$

10. (5 points) Consider two p.d.f.'s $f_0(x)$ and $f_1(x)$ that are defined as follows: $f_0(x) = \begin{cases} 2x, & \text{for } 0 \le x \le 1, \\ 0, & \text{otherwise,} \end{cases}$ and $f_1(x) = \begin{cases} 1, & \text{for } 0 \le x \le 1, \\ 0, & \text{otherwise.} \end{cases}$ Suppose that a single observation $X$ is taken from a distribution for which the p.d.f. $f(x)$ is either $f_0(x)$ or $f_1(x)$, and the following simple hypotheses are to be tested: $H_0: f(x) = f_0(x)$, $H_1: f(x) = f_1(x)$. (a) Describe a test procedure (specifying how to reject $H_0$) for which $\alpha(\delta) \le 0.01$ and $\beta(\delta)$ is a minimum. Reject $H_0$ if (b) Determine the minimum value of $\beta(\delta)$ attained by the procedure in Part (a).

1. A 3000 kg mass was moved up by an external force at a constant speed to a height of 200 m in 20 s. What was average power exerted by the external force in lifting up the object? 2. A 5 kg object was moving on a smooth surface at a speed of 5 m/s on a level surface. An external force of 100 N acts on the object over a distance of 10 m, at an angle of 60° above the horizontal. What is the new speed of the object? 3. A 10 kg object was positioned at a height of 1.0 m above the surface of a relaxed spring. When the object was released from rest it compressed the spring by 10 cm, before coming to rest. What is the spring constant? 4. An inclined smooth slide is 6 m long that makes an angle of 30° above the horizontal. A 100 kg person slides down. What was his speed when he reached the ground? 5. Earth and moon are separated by a distance of 3.82x10$^m$. The mass of earth is 5.98x10$^{24}$ kg. kg and that of moon is 7.36x10$^{22}$ kg.
