The correct answers can be found on the Pearson website. Consider the following matrix: [4 90 85 75
2 55 65 75
x = 3 78 82 79
1 84 92 93]
1. Use the size function to determine the number of rows and columns in this matrix.
2. Use the sort function to sort each column in ascending order.
3. Use the sort function to sort each column in descending order.
4. Use the sortrows function to sort the matrix so that the first column is in ascending order, but each row still retains its original data. Your matrix should look like this:
[1 84 92 93
2 55 65 75
x = 3 78 82 79
4 90 85 75]
5. Use the sortrows function to sort the matrix from Exercise 4 in descending order, based on the third column.

Which linear equations have an infinite number of solutions? check all that apply.  (x  –  3/7)  =  2/7(3/2x  –  9/14)8(x  +  2)  =  5x  –  1412.3x  –  18  =  3(–6  +  4.1x)(6x  +  10)  =  7(x  –  2)4.2x  –  3.5  =  2.1 (5x  +  8)

Find the area and perimeter of each composite figure. use 3.14 for π. round your answer to the nearest tenth. a square and a right triangle share a common side. image long description a 3-meter by 0.5-meter rectangle has triangles attached like wings to the 3-meter sides. the other two sides of both triangles measure 2.5 meters. the height of each triangle is 2 meters. a 6-inch by 4-inch rectangle has 2 half-circles attached like wings to the 6-inch sides. the radius of each half-circle is 3 inches. find the surface area and volume of each figure. use 3.14 for π. round your answer to the nearest tenth. a right circular cylinder has a base radius of 6 yards and a height of 20 yards. a rectangular prism has a base that is 9 centimeters long and 7 centimeters wide. the height is 2 centimeters. a rectangular prism has a base that measures 11 millimeters by 11 millimeters. the height is 11 millimeters.
