1) Solve with reduction of order. y" + 7y' - 18y = ex + e2x
(1 point) Use the substitution method to solve the system: 2x + 7y = -24 3.C - 8y = 38 The solution is: = y=
Use reduction of order y'' + 7y' - 18y = ex + e2x
(10 point) Solve the following initial value problems. a) y"+ 4y' + 8y = 40cos(2x), y(0) = 8, y'(0) = 0 b) y" + 6y' + 13y = 12e-3xsin(2x), y(0) = 0, y'(0) = 0 (10 point) Find a general solution of each of the following nonhomogeneous equations. a) y" + 4y = 12x−8cos(2x) b) y(4)− 4y" = 16+32sin(2x)
I'm trying to solve this problem: Let Y ~ Bin (8, 0.5) Find E(7Y - 36Y2 + 8Y -4) I know how to simplify all the terms except for E(7Y), so what I have so far is: E(7Y) - 36V(Y) + 8E(Y) - 4. How do I simplify E(7Y) so that I can solve the problem?
3. Solve the system of equations: (-x - 7y = 14 1-4X – 14y = 28 4. Solve the system of equations: 3x - 2y = 2 (5x - 5y = 10 5. Solve the system of equations: (2x + 8y = 6 1-x - 4y = -3
The Golus Elimination method: Example: Solve the system: 2x +y +2 = 5 4x-by = -2 -2x + 7y +22=9
1.Find the partial derivatives of the function f(x,y)=(8x+8y)/(6x-7y) fx(x,y)= fy(x,y)=
Solve the system. 7w + 7x + 7y + 7z = -7 2w + 2x + 2y + 5z = -1 w + 2x + y + 2z = 6 If the system has one solution, enter it below. If the system has infinitely many solutions, enter the solution for which the value of each arbitrary variable is set to 9. If the system has no solution, enter "N" for each variable. w= x= y= z=
Use matrices to solve the following system of equations: 2x − 7y = 1 5x + 3y = 8
