Problem 3 When a man stands near the edge of an empty drainage ditch of depth 2 m, he can barely see the boundary between the opposite wall and bottom of the ditch as shown in the below left figure. The distance from his eyes to the ground is 1.5 m a) What is the horizontal distance d from the man to the edge of the drainage ditch if the angle $\theta = 31^\circ$? b) After the drainage ditch is filled with water (n = 1.333) as in the below right figure, what is the maximum distance the man can stand from the edge and still see the same bottom edge of the ditch? c) If the drainage ditch is filled with soybean oil (n = 1.5), will the person be able to see the bottom edge while standing in the same spot as part b?

Without a functional NADPH oxidase enzyme, neutrophils are still able to phagocytose pathogens into phagosomes.
Write all elements and subgroups of $S_3$. 3. Write all elements of $A_4$. Prove that $A_n \leq S_n$.
The function f(x)=(7x-8)e^(2x) has one critical number. Find it. x= The function f() = (7 -- 8)e2 has one critical number. Find it. c=
For $n \ge 0$, let $F_n$ denote the $n$-th Fibonacci number (i.e. the recursively defined sequence $F_n = F_{n-1} + F_{n-2}$ with base case $F_0 = 0$, $F_1 = 1$). Prove that, for all $n \ge 0$, $\sum_{i=0}^{n} F_i = F_{n+2} - 1$
A 90 kg client is receiving Dobutrex (500 mg in 250 mL) at 8 mL per hour (mL/hr) by an electronic infusion device. The recommended dosage range is 2.5-10 mcg per kg per minute (mcg/kg/min). Is the client receiving a safe dose?
In prokaryotes, which of the following is true? There is concurrent transcription, translation, and degradation of the mRNA. Translation occurs after transcription is finished. Translation occurs after the mRNA is exported out of the nucleus. There is concurrent transcription and translation of the mRNA in the 3′ to 5′ direction. Degradation of the mRNA occurs in the lysosome.

A simple seismometer used to measure ground motion is shown in the figure below. If the mass $m = 317.9913$ kg, stiffness $k = 2869.6806$ N/m and damper $c = 697.7579$ Ns/m, determine the lowest frequency of ground vibration that can be measured by the seismometer if the reading is not exceed the actual amplitude of the ground by more than $p = 1.3421$ %. Note: Ignore free (transient) response in the solution of this problem.
