Consider relations R(A, B, C), S(C, D, E) and T(E, F, G). Find a re- lational expression which (1) is equivalent to IIA,F(OB

Determine whether the statement below is true or false. Justify the answer.   A general solution of a system is an explicit description of all solutions of the system. Choose the correct answer below.     A. The statement is false. Each different choice of a free variable produces the same solution of the system.   B. The statement is true. After applying the row reduction algorithm and generating a general solution of a​ system, the rightmost column displays all of the particular solutions of that system.   C. The statement is false. A general solution is the result of an inconsistent​ system, which has no particular solution.   D. The statement is true. The row reduction algorithm leads directly to an explicit description of the solution set of a linear system when the algorithm is applied to the augmented matrix of the​ system, leading to a general solution of a system.

Mixture Problems My Sol A 1500 gallon tank initially contains 600 gallons of water with 5 lbs of salt dissolved in it. Water enters the tank at a rate of 9 gal/hr and the water entering the tank has a salt concentration of (1 + cos(t)) lbs/gal. If a well mixed solution leaves the tank at a rate of 6 gal/hr, how much salt is in the tank when it overflows? Solve the equation via MATLAB making sure that you passed though the following: 1. Initialization of variables 2. Setting up the Volume Equation 3. Settimg Up the differential equation 4. Listing down initial Conditions 5. Plugging in Conditions. 6. Finding the resulting model 7. Finding the concentration when the tank overflows 8. Graph the solutions
