Q. Solve the equation.dxdy=xe−y+10e−yChoose 1 answer:(A) y=2x2+10x+C(B) y=−ln(−2x2−10x+C)(C) y=ln(2x2+10x+C)(D) y=−ln(−2x2−10x)+C
Recognize Separable Equation: Recognize that the given differential equation is separable, meaning we can separate the variables y and x on different sides of the equation.dxdy=xe−y+10e−yWe can write this as eydy=(x+10)dx.
Integrate with Respect: Integrate both sides of the equation with respect to their respective variables.∫eydy=∫(x+10)dx
Perform Integration: Perform the integration.The integral of ey with respect to y is ey, and the integral of (x+10) with respect to x is (x2)/2+10x.So we have ey=(x2)/2+10x+C, where C is the constant of integration.
Solve for y: Solve for y by taking the natural logarithm of both sides.y=ln(2x2+10x+C)
Check Answer Choices: Check the answer choices to see which one matches our solution.The correct answer is (C) y=ln(2x2+10x+C).
