Covert the differential equation into a system and solve the system: D2-2D-8y

Solve the following equations system 0.1V, – j0.2V, =1 - j0.2V, +(0.2+ j0.3)V, = j0.5 ans V= 3.3333 + 3.3333i V, =1.6667 + 3.3333i

Find the ordered-pair solution of y=2/5x+2 that corresponds to x= -5.

Solve the no lineal equation

Solve for y: y = x³ + y = xy + a a

Solve:y′′ −6y′ +5y = e4x

A King in ancient times agreed to reward the inventor of chess with one grain of wheat on the first of the 64 squares of a chessboard. On the second square, the King would place two grains of​ wheat, on the third​ square, four grains of​ wheat, and on the fourth square eight grains of wheat. If the amount of wheat is doubled in this way on each of the remaining​ squares, how many grains of wheat should be placed on a square 16​? Also, find the total number of grains of wheat on the board at this time and their total weight in pounds.​ (Assume that each grain of wheat weighs​ 1/7000 pounds.)
