Expert Solution & Answer
Chapter 3, Problem 56E
Explanation of Solution
Truth table:
The truth table will specifies the output condition for every input. The input values are all possible binary values of the input. Hence for “n” inputs, there are 2n possible combinations.
The task is to design a circuit that outputs an error BCD (Binary Code Decimal) format. In that format, every decimal digit 0 to 9, is coded as its binary equivalent.
The number of bits required to code the digits 0 to 9 that is 10 digits is Ceiling [log2 (10)] = 4.
The first 10 binary codes that is 1010 to 1111, the error bit would be 1, since all these are invalid codes. This is because there are only 10 digits in the decimal system.
The below truth table will show the error function:
| w | x | y | z | E |

11. Go to the Webinars worksheet. DeShawn wants to determine the number of webinars the company can hold on Tuesdays and Thursdays to make the highest weekly profit without interfering with consultations, which are also scheduled for Tuesdays and Thursdays and use the same resources.
Use Solver to find this information as follows:
a. Use Total weekly profit as the objective cell in the Solver model, with the goal of determining the maximum value for that cell.
b. Use the number of Tuesday and Thursday sessions for the five programs as the changing variable cells.
c. Determine and enter the constraints based on the information provided in Table 3.
d. Use Simplex LP as the solving method to find a global optimal solution.
e. Save the Solver model below the Maximum weekly profit model label.
f. Solve the model, keeping the Solver solution.

- I want to ask someone who has experiences in writing physics based simulation software. For context I am building a game engine, and want to implement physics simulation. There are a few approaches that I managed to find, but would like to know what are other approaches to doing physics simulation entry points from scenes, would you be able to visually draw me a few approaches (like 3 approaces)?
