A set of complex numbers is specified. Determine all the boundary points and whether the set is open, closed, open and closed, or not open and not closed. Specify all boundary points of the set (whether or not they belong to the set). V is the set of all z with $2<\operatorname{Re}(z) \leq 3$ and -1 < Imz < 1.

What is specific energy in an open channel flow?

For the given function, find (a) the critical numbers; (b) the open intervals where the function is increasing; and (c) the open intervals where it is decreasing.

$$f(x) = x^{6/7} - x^{13/7}$$

Fill in the blanks.

If f is differentiable on an open interval (a, b) and _____ on (a, b), then f is decreasing on (a, b).

For the given function, find (a) the critical numbers; (b) the open intervals where the function is increasing; and (c) the open intervals where it is decreasing.

$$f(x) = x^{16/17} - x^{33/17}$$

A friend tells you that aluminum lies beneath the layer of white plastic on a refrigerator door. How could you check to see if this is true (without any scraping)?

An organ pipe is made to play a low note at $27.5 \mathrm{~Hz}$, the same as the lowest note on a piano. Assuming a sound speed of $343 \mathrm{~m} / \mathrm{s}$, what length open-open pipe is needed? What length open-closed pipe would suffice?

Choose an appropriate metric unit and estimate given of the following measures (check your estimates).
a. The thickness of the top of a desk
b. The length of this page of paper
c. The height of a door

In the previous problem suppose your friend in the car measures the width of the car door to be $90 \mathrm{~cm}$. You also measure the width as he goes by you. How will your value for the door width compare to his? (1) Your value will be smaller. (2) Your value will be larger. (3) Your value will be the same. (4) You cannot compare the widths, as the answer depends on the car's speed.

The Thevenin equivalent impedance is the impedance looking from (a) the source with the output shorted (b) the source with the output open (c) any two specified open terminals with all sources replaced by their internal impedances (d) any two specified open terminals with all sources replaced by a short

All of the following are true regarding customer service skills except which one?

A. Customers (and/or stakeholders) are the reason for the project

B. Projects that have customers (and/or stakeholders) who are external to the organization have a higher priority than internal projects

C. Customers (and/or stakeholders) may be internal or external to the organization

D. Satisfying customer expectations (and/or stakeholder expectations) and delivering the project on time and on budget is the primary focus for all customers and stakeholders

For the given function, find (a) the critical numbers; (b) the open intervals where the function is increasing; and (c) the open intervals where it is decreasing.

$$f(x) = 2.9 + 5.6x - 1.3x^2$$
