Figure 1. One pоssible dаtаbаse state fоr the COMPANY relatiоnal database schema. Specify the following queries on the database schema shown in Figure 1 using the relational operators (relational algebra). Retrieve the names of employees in department 5 who work more than 10 hours per week on the 'Computerization' project. List the names of employees who have a dependent with the same first name as themselves. Find the names of employees that are directly supervised by 'Jennifer S. Wallace'. NOTE: Express each of the provided information needs as a relational algebra query using only projection (π), selection (σ), renaming (ρ), inner joins (⋈), set union/intersection (∪, ∩), and division (/). You may write your queries using either the symbol (i.e. π) using the 'Insert Math Equation' option or the operations' word terminology (i.e. projection).
