Problem #2: Consider the following vectors, which you can copy and paste directly into Matlab. x = [2 1 4 3 2 4 3 1 1]; у [4 2 4 4 4 6 4 6]; = Use the vectors x and y to create the following matrix. 0 0 0 0 2 4 4 1 2 0 0 0 0 0 0000 0 2 4 4 0 0000 0 0 0 4 3 40000 0 0 4 2 4000 0000446 00 000006 340 000000416 000000061 Such a matrix is called a tri-diagonal matrix. Hint: Use the diag command three times, and then add the resulting matrices. To check that you have correctly created the matrix A, verify that det(A) = 9.0624e+05. Find the dominant eigenvalue of A.

An investigation of the properties of bricks used to line aluminum smelter pots was published in an article. Six different commercial bricks were evaluated. The life span of a smelter pot depends on the porosity of the brick lining (the less porosity, the longer the life span); consequently, the researchers measured the apparent porosity of each brick specimen, as well as the mean pore diameter of each brick. See the table. Apparent Porosity (y). Mean Pore Diameter (x). Click the icon to view the table. Data table Mean Pore Diameter Apparent Porosity (%) (micrometers) Brick Interpret the y-intercept of the line. Choose the correct answer below. 18.7 12.0 В 18.3 9.8 O A. The y-intercept is Bo- This value has no meaning because 0 is not in the observed range of the independent variable mean pore diameter. 16.3 7.3 6.9 5.4 O B. The y-intercept is Bo: For each unit increase in mean pore diameter, the mean porosity is estimated to increase by B0- 17.2 10.9 O C. There is not enough…
