Consider a right rectangular prism:

a. Edge AF is perpendicular to (makes right angles with) which of these? (The bar notation is common for line segments.)

edge FE, or $\overline{F E} \quad$ edge AD, or $\overline{A D} \quad$ edge AB, or $\overline{A B}$

segment AG, or $\overline{A G} \quad$ segment BF, or $\overline{B F} \quad$ segment FH, or $\overline{F H}$

b. Name the endpoints of three edges that are parallel to edge AD.

Starting with acetylene, show reagents that you would use to prepare each of the following compounds: (a) 1-Butyne (b) 2-Butyne (c) 3-Hexyne (d) 2-Hexyne (e) 1-Hexyne (f) 2-Heptyne (g) 3-Heptyne (h) 2-Octyne (i) 2-Pentyne

In this exercise, use a calculator to find the value of the trigonometric function to four decimal places.

$$\csc 1$$

Integrate

$$\int \sec x \tan x d x$$

For the following exercise,

Find the exact value of each trigonometric function.

Karl Marx predecía la muerte del sistema Capitalista afirmando que en el largo plazo...

A) Los capitalistas no tendrán a quien contratas para producir.

B) La clase trabajadora producirá sus propios bienes y servicios para satisfacer sus necesidades.

C) La concentración del capital generara desocupación e impedirá que el mercado se autorregule.

In this exercise, use a calculator to find the value of the trigonometric function to four decimal places.

$$\tan 3.4$$

In this exercise,, suppose that f(u, v)=ue$^v$, where u=rs and v=r+s.

What is the value of f(u, v) at(r, s)=(1,1)?

Karl ralses his hand and Informs Ms. Rhombi that he has discovered another property related to the angles of an inscribed quadrilateral. He claims that the measure of any exterior angle of the quadrilateral is equal to the measure of the opposite interior angle in the quadrilateral. In other words, $m \angle A W Z=m \angle Y$. Explain Karl's reasoning.

In this exercise, find the exact value of the expression.

$$\cos \left(\arctan \dfrac{3}{4}\right)$$

A car under surveillance accelerates at a constant rate from 0 mph to 60 mph in 30 sec. How far has it traveled after 30 sec?

In this exercise, solve for the value of x that will satisfy the given equation.

$${ }_6 P_2=x\left({ }_5 P_3\right)$$

In this exercise, verify the identity algebraically. Use a graphing utility to check your result graphically.

$$\frac{\sec \theta-1}{1-\cos \theta}=\sec \theta$$
