The purpose of this problem is to show a connection between second order linear equationsand first order systems of equations. It also provides an example of why linear systems ofdifferential equations are worth studying (assuming you think second order linear equationsare worthwhile). Consider the second order linear equation ax'' + bx'' + cx =0

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
