- Please provide steps for how you got the solution to the problem provided below, I am trying to understand the problem, not just see an answer. Thank you so much. A space ship warp engine has enough energy to perform two warp jumps going between star systems (i.e., the warp battery has 2 units of charge). The ship can operate in two modes: survey the current system or charge battery. On a given day the ship will complete the survey of the current system with probability 0.24. Then, if battery has capacity, it will move to a new system, consuming 1 unit of charge. If the battery is empty, the ship will switch to the charging mode. In the charging mode, the ship will recover 1 unit of charge on a given day with probability 0.95. The ship will stay in the charging mode until the battery is full. Model the behavior of the ship as a Markov chain.arrow_forwardUse GFSA (Given, Find, Solution, and Answer) on the given space below.

- Detailed explanation of each step so I could study for a test C6M.7 Astronomers currently believe that every galaxy has a supermassive black hole at its center and that a typical galaxy has collided with other galaxies several times since the beginning of the universe. Imagine that the central black holes of two colliding galaxies end up, after the collision, orbiting each other in the middle of a cloud of dust and stars. Assume that the black holes have the same mass M (which maybe millions or even billions of times that of the sun) and each is initially in a circular orbit of radius R around the pair’s center of mass (which is halfway between them), and the surrounding cloud has no net angular momentum, as shown in figure C6.14. Over time, frictional interactions with the cloud cause the black holes to slowly spiral in toward each other. If their orbits remain approximately circular as they slowly spiral in, then thespeed of each in its circular orbit will be │V│ = 1/2 (GM/r)^1/2,…arrow_forwardSolve the following problems, show complete and clean solution and box your final answer. Thank you.arrow_forwardWrite a CR for the solved problem. A example of one is attached as well. The problem about the ROCK is the example CR. The problem you ARE writing a CR for is 5x^2-8x=3. Instructions below. For the CR's, claim you should answer the question of , do you get 2 real solutions, 1 real solution, or 2 complex solutions? For your reasoning you should explain how you know. Use the example attached to help you answer. hints: that plus minus sign means there are two answers. If the number under the square root is positive, you have two real solutions. If the number is negative you have two complex solutions. If the number is 0 under the square root you have 1 real number solution.arrow_forward
