- 09.......arrow_forwardEXAMPLE: The sum of any two even integers is even. Answer: Proof. (direct) Suppose x and y are even integers. By definition of even, let x = 2k and y = 2j for some integers j and k. Then, x+y=2k+2j = 2(k + j) Note that k+j is an integer because it is the sum of integers. Therefore, by definition of even, x + y is even.arrow_forward2. Compute the kinetic energy, in joules, of a 3 g rifle bullet travelling at 300 m/s.arrow_forward

- Question 1 : (Solve quadratic equations) The two roots of a quadratic equation ax? + bx + c = 0 can be obtained using the following formula : -b + V² – 4ac -b – Vb – 4ac and n = 2a 2a b² - 4ac is called the discriminant of the quadratic equation. If it is positive, the equation has two real roots. If it is zero, the equation has one root. If it is negative, the equation has no real roots. Write a program Equation.java for solving a quadratic equation that prompts the user to enter values for a, b, and c and displays the result based on the discriminant. If the discriminant is positive, display two roots. If the discriminant is 0, display one root. Otherwise, display "The equation has no real roots". Note that you can use Math.pow(x, 0.5) to compute the discriminant. Here are some sample runs. Enter a, b, c: 1.0 3 1 -Enter The equation has two roots -0.381966 and -2.61803 Enter a, b, c: 1 2.0 1 -Enter The equation has one root -1 Enter a, b, c: 1 2 3 -Enter The equation has no real…arrow_forward(B) Find the result of the following equation: A = 3² + 3+3² √2arrow_forward2) Use Simpson and calculates the trape zoidal sules following integral.. to Also write Code for both these methodarrow_forward

The density of aluminum is 2.70 g/cm³. Assume each aluminum atom supplies one conduction electron per atom. Find the drift speed of the electrons in the wire. 1.95E-4 The equation for the drift velocity includes the number of charge carriers per volume, which in this case is equal to the number of atoms per volume. How do you calculate that if you know the density and the atomic weight of aluminum? mm/sarrow_forward
