A duck is trying to get from point A (0, 0) to point B (13, 8) without overshooting, but he can only move up or right. He always alternates his step sizes between moving 1 units in a single direction and moving 4 units in a single direction. Compute the number of ways the duck can start at point A and end at point B please answer in typing format
1.) Create an m-file with the name exercise_2_first_name_last_name. 2.) Use linspace() to create an array of times, call it t, from 0 to 5 with 200 points. 3.) Plug the points in t into the following equations: y, (t) = -4.9t2 + 3t and y,(t) = -4.9t2 + 7t where t is in seconds and y is in meters. These equations represent the heights of two objects thrown directly upward with initial positions y = 0 and initial speeds 3" and 7. 4.) Create a figure showing two graphs with the plot command. Graph one equation as green circles and the other as blue dots. You'll want to add the hold on command before the plot commands. It’ll let you graph more than one set of data points. 5.) Add the following labels using xlabel and ylabel: time (s) and height (m). When we graph quantities with units, we include the units in parenthesis directly after the name of the quantity. The reader must know what units are being plotted since they represent real quantities. 6.) Add the following title: Heights vs.…

We want to count step-by-step paths between points of the form (x, y) in the plane with integer coordinates. Only two kinds of steps are allowed: a right-step which increments the x coordinate, and an up-step with increments the y coordinate. How many paths are there from (0,0) to (10, 10) that go through (5, 5)? Express your answer as an integer. The WolframAlpha calculator e accepts factorial !, combinations C(n, k), and permutations P(n, k) notation to help you produce an integer value based on the course formulas.
