AVANTIVE Corporation has five departments: administration, marketing, sales, shipping, and purchasing. Each department employs many employees. Each employee has an ID, a name, a home address, a home phone number, and a salary and tax ID (Social Security number). Some employees are classified as sales representatives, some as technical support, and some as administrators. Sales representatives receive a commission based on sales. Technical support employees are required to be certified in their areas of expertise. For example, some are certified as drivetrain specialists; others, as electrical systems specialists. All administrators have a title and a bonus. Given that information, create the ERD containing all primary keys, foreign keys, and main attributes.

#### How fast was the gender gap expanding or shrinking

#### Write the rule for the function f giving the ratio

Write the rule for the function f giving the ratio of the number of bachelor's degrees earned by women to that of men in year t, with t = 0 corresponding to 1960. Hint: the

#### Prepare a list of questions that harry needs

After pondering this memo for several days, Harry scheduled a meeting with Bill so that he could clarify Bill's vision of this venture. Using the standard content of a syste

#### Find the charge through the wire with respect to time

(A)* Direct current in steady state does not vary with time. If a DC currentof 5 A flows through a wire, find the charge through the wire with respect to time. The charge at

#### Calculate the resistance of the shoe

The safety shoe can be modeled as a resistance that is located in series with the 240 V voltages (see Figure P2.45 b). In this situation, the current drops to 40 mA. Calcula

#### Compute the side-length of a square plate capacitor

if the smallest observable voltage is 0.1 V, compute the side-length of a square plate capacitor that can detect one electron, assuming the dielectric is air with relative p

#### Plot the voltage and current flow through the inductor

Given the voltage source is 5sin(πt), current through an inductor is turned on at time, t = 0, as shown in Figure P4.37. Use PSpice to plot the voltage and current flow thro

#### Draw the waveform of the power absorbed by the device

The voltage and the current across an electrical device are shown in Figure P2.57 . The voltage and the current are associated in their direction. Draw the waveform of the p
