Unformatted text preview: 4. To manufacture an automobile requires painting, drying, and polishing. Mega Motor Company produces three types of cars. The required painting, drying and polishing times for each type of car are shown in the table below. If the company has 240 hours for painting, 69 hours for drying, and 41 hours for polishing per month, how many of each type of car are produced per month? Hours for Painting Type 1 Car Type 2 Car Type 3 Car Hours for Drying 10 16 3 5 8 Hours for Polishing 2 3 -N a. Clearly define the variables in this problem: 1= Hours painting 1= Hours 9 Drying 2- Hours of polishing b. Write the equations for this problem. 10 16 8 3 5 2 69 41 c. Solve the system of equations using using the inverse matrix. For each create the matrix equation in the form AX' - B. Show steps in solving the matrix equation, including 4"(inverse of the A matrix) IN FRACTIONAL FORM. Clearly show the final solution matrix. 501" : - 10 x + 104+ 82 = 240 8 7 + 54 +22 = 69 10 2x+ 34+2 = 41 16 8 240 3 2 5 59 41 - 4 4 3 - 2 240 69 d.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
