Write general purpose m-files to 1. multiply two signals 2. add and subtract two signals 3. shift signals by any sample generate two sinusoidal signals of the form cos (on). with 01 = b/10 and 02 = b/5, where b is your birth month, test the three functions and plot the results including x1 (n) = cos (n01) and x2 (n) = cos (n 02) let the signals you consider span the indices from -b to +b, where b is your birth month, too.

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
