First mechanical computer Explanation: First mechanical computer or automatic computing engine concept. In 1822, Charles Babbage conceptualized and began developing the Difference Engine, considered to be the first automatic computing machine. The Difference Engine was capable of computing several sets of numbers and making hard copies of the results.
Formation of the universe and formation of solar system Answer: Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust. Squeezing made the cloud start to collapse, as gravity pulled the gas and dust together, forming a solar nebula. Just like a dancer that spins faster as she pulls in her arms, the cloud began to spin as it collapsed. Eventually, the cloud grew hotter and denser in the center, with a disk of gas and dust surrounding it that was hot in the center but cool at the edges. As the disk got thinner and thinner, particles began to stick together and form clumps. Some clumps got bigger, as particles and small clumps stuck to them, eventually formingplanets or moons . Near the center of the cloud, where planets like Earth formed, only rocky material could stand the great heat. Icy ma...
Which of the following coordinates of points belong to the solution set of the inequality y<2x2+5x-1? A.(-3,2) B.(-2,9) C.(1,6) D.(3,1) Answer: D. (3, 1) Step-by-step explanation: The solution set of inequality is the set of all solutions. Solving linear inequalities is very much like solving linear equations, with one important difference. When you multiply or divide both sides of an inequality by a negative number, the direction of the inequality is reversed. Substitute the choices values for x and y to satisfy the equation. A. (-3, 2) Therefore, choice A does not satisfy the equation. B. (-2, 9) Therefore, choice B does not satisfy the equation. C. (1, 6) Therefore, choice C does not satisfy the equation. D. (3, 1) Therefore, choice D will make the equation correct. #BrainlyEveryday For more information for solving inequalities, please refer to this link: brainly.ph/question/6647146
