Could you explain in depth what the question is asking and have clear steps so I can understand the code, which should be in c++Thank you! This exercise will make use of numerical integration to get a solution to an ordinary differ-ential equation (ODE). We will solve the ODE,dydt=(1)This particular equation could be a model for reactions in chemistry, biology and evenastrophysics. y would represent something that is being created from a finite supply of reactants.For example, it might measure the end product of a chemical reaction like 2 H₂ + O₂ → 2 H₂O.Here we would have y = nH₂O/nH₂,initial. The reaction rate is proportional to the remainingreactants (1-y) nH₂/n2,ini2,initial and other factors included in a. In practice a would be afunction of the environment (temperature, density, etc...) but for simplicity we will keep aconstant. We will start from y(0) = 0. This ODE then has the following exact, analyticalsolution which is convenient for checking our answers,y(t)=1-e=a(1 — y).-a t(2)In general, numerical solvers can handle highly non-linear ODEs that do not have analyticalsolutions. The choice of solver requires considering complexity, stability and accuracy (smallerrors!). In general more accuracy requires smaller steps or a better method.In this homework we will make use of the PGPLOT library. Please refer to the lecture notesabout PGPLOT for more information.You can use ploty.cpp and its Makefile from /home/2G03/ploty as a basis to do thisexercise. Remember to change the names in the Makefile.1.1 We will use the exact expression (equation 1) for din our code. Write a function calleddydt to evaluate it for specific input y and a values. Call it when you need the rate of changeof y throughout this homework. You can keep the function and the main program in one filein all the exercises. The function declaration should look like:double dydt ( double y, double a)Note that the rate does not depend on explicitly on t so you do not need t as an argument,just y and a.In a file called testdydt.cpp, include your function code and also write a simple mainprogram that calls the function dydt. The main program should call it with the argumentsy = 0.5 and a = 0.04 and y = 0.2 and a = 0.4. Use cout to print the values to the terminal.1Compile and link testdydt.cpp into a program called testdydt. The program only needs to dothe test and nothing else. Report the rates from your program for these cases, dydt (0.5, 0.04)and dydt (0.3,0.3).

Correct answer will be upvoted else downvoted. Computer science. in case there are two planes and a molecule is shot with rot age 3 (towards the right), the cycle is as per the following: (here, D(x) alludes to a solitary molecule with rot age x) the primary plane delivers a D(2) to the left and lets D(3) progress forward to the right; the subsequent plane delivers a D(2) to the left and lets D(3) progress forward to the right; the primary plane lets D(2) forge ahead to the left and creates a D(1) to the right; the subsequent plane lets D(1) progress forward to one side (D(1) can't create any duplicates). Altogether, the last multiset S of particles is {D(3),D(2),D(2),D(1)}. (See notes for visual clarification of this experiment.) Gaurang can't adapt up to the intricacy of the present circumstance when the number of planes is excessively huge. Help Gaurang find the size of the multiset S, given n and k. Since the size of the multiset can be extremely huge, you…

Correct answer will be upvoted else downvoted. Computer science. You are given three positive (more prominent than nothing) integers c, d and x. You need to track down the number of sets of positive integers (a,b) with the end goal that balance c⋅lcm(a,b)−d⋅gcd(a,b)=x holds. Where lcm(a,b) is the most un-normal various of an and b and gcd(a,b) is the best normal divisor of an and b. Input The primary line contains one integer t (1≤t≤104) — the number of experiments. Each experiment comprises of one line containing three integer c, d and x (1≤c,d,x≤107). Output For each experiment, print one integer — the number of sets (a,b) to such an extent that the above uniformity holds.
For the following problem we want to find a linear equation that passes through the following two points: (-5,8), (7,-9). The general equation for a line is: y = mx + b a Create two symbolic variables, m and b. Looking at the general equation above, we can subtract y from both sides to get the following expression: 0 = mx + b-y. Now that our equation is in this format, we can create two equations, eqn1 and eqn2 using the two (x,y) coordinates given above. Use the solve function to solve the system of equations. Call these solutions sol m and sol b. Plot the solution of the line that passes through the two points (create the line using sol m and sol b and define a new symbolic variable, x). Label the axes and give the plot a title. Change the line to a magenta dash-dotted line and limit both x and y axes from - 10 to 10
Let l be a line in the x-yplane. If l is a vertical line, its equation is x = a for some real number a. Suppose l is not a vertical line and its slope is m. Then the equation of l is y = mx + b, where b is the y-intercept. If l passes through the point (x₀, y₀), the equation of l can be written as y - y₀ = m(x - x₀). If (x₁, y₁) and (x₂, y₂) are two points in the x-y plane and x₁ ≠ x₂, the slope of line passing through these points is m = (y₂ - y₁)/(x₂ - x₁). Instructions Write a program that prompts the user for two points in the x-y plane. Input should be entered in the following order: Input x₁ Input y₁ Input x₂
The size of a colony of blue bacteria growing in a petri dish is modeled by the equation where t is time in days. The size of a colony of green bacteria is modeled by the equation where t is again time in days. Both colony sizes are measured in square centimeters. Part A: Graph the growth of both colonies on the same plot over the course of 6 days in one hour increments. One way to get one hour increments is to use a step size of 1/24. Another way is to use linspace and specify that it should create 6days x 24hours evenly spaced values. In either case, make sure you start at 0 days, not 1 day. Make the color of the curve match the color of the bacteria it represents. Give your graph a title and axis labels. Part B: How large is the green bacteria colony when the blue colony reaches its maximum size. You must answer this question using Matlab calculations, not manually entering the answer. To check your work, the blue colony’s maximum size is 270.56 and when it reaches that…
