Explanation of Solution

Consider the following grammar in BNF:

<assign> -> <id> = <expr>

<id> —> A|B|C

<expr> -> <expr> + <term> | <term>

<term> -> <term> * <factor> | <factor>

<factor -> (<expr>)| <id >

Rewriting the BNF to add the “++” and “—-“ unary operators of Java...

Please show the code for the Tikz figure of the complex plane and the curve C. Also, mark all singularities of the integrand.
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. Table 3: Solver Constraints Constraint Cell or Range Each webinar is scheduled at least once on Tuesday and once on Thursday B4:F5 Each Tuesday and…
