A) determine the analytical function, y(t), that is the convolution of the following rectangle function with itself: xlt =ut -uſt-5), that is: y(t)=x(t) ⓡx(t). use matlab to plot or draw by hand the plot or x(t) and y(t). b) determine the analytical function, y(t), that is the convolution of the following two rectangle functions: x(t)= (ult) –uſt–5)) and z(t)=3(u(t) -uſt- that is: y(t)=x(t)®z(t). use matlab to plot or draw by hand the plot or x(t), z(t) and y(t).

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
