Problem 4: How many paths in the integer lattice Z? are there which • only use north-steps (0, 1) and cast-steps (1,0), start at the origin (0,0), • end at the point (30, 60), and • go through the point (10, 20)?

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.…
A monkey has filled in a 3 × 3 grid with the numbers 1, 2, . . . , 9. A cat writes down thethree numbers obtained by multiplying the numbers in each horizontal row. A dog writesdown the three numbers obtained by multiplying the numbers in each vertical column.Can the monkey fill in the grid in such a way that the cat and dog obtain the same listsof three numbers? What if the monkey writes the numbers 1, 2, . . . , 25 in a 5×5 grid? Or1, 2, . . . , 121 in a 11 × 11 grid? Can you find any conditions on n that guarantee that itis possible or any conditions that guarantee that it is impossible for the monkey to writethe numbers 1, 2, . . . , n^2 in an n × n grid so that the cat and the dog obtain the same lists of numbers? Please provide a mathematically rigorous solution with proofs that could be understood by a person at a high school level.
3. The fractal C is constructed as follows. (i) Begin with the line segment Io = [0,1]. (ii) Remove the open middle third (}, }), to get I = [0, ] U [G, 1). (iii) Remove the open middle third from every remaining line segment, to get [2 1] I2 = [0, (iv) Repeat the process of removing the open middle thirds of the remaining line segments infinitely many times. The first few iterations of this construction are illustrated below. (a) Find the total length of the intervals removed from [0, 1] after three iterations, i.e. the total length of the intervals removed from [0, 1] to get Iz. (b) By considering a suitable series, show that the total length of all of the intervals removed is equal to 1. (c) Despite the fact that an infinite number of intervals of total length 1 have been removed to construct C, there are points in the interval [0, 1] that will never be removed, i.e. there are points in C. What is one such point?
7. The number t₁ = 1 + 2 + +n is called the nth triangular number (so called because t, dots may be inserted in an orderly fashion in an equilateral triangle; the fourth triangular number is familiar to bowlers). Some triangular numbers are also squares (which means that the dots may be rearranged into a square), for example, tg = 6²,149 = 35². Show that there are infinitely many numbers that are simultaneously triangular and square. this is a number theory problem
