Solve the given differential equation. (The form of yp is given.)D2y - y = 3 + x2 (Let yp = A + Bx + Cx2.)
A. y = c1ex + c2e-x + 5 - x2 B. y = c1ex + c2xex - 5 - x2 C. y = c1ex + c2e-x - 5 - x2 D. y = c1ex + c2e-x - 5 + x2
Determine whether S defines a function.S = {(-4, 9), (-3, 5), (2, -6), (5, 1)}
A. Yes B. No
Two chemical solutions, one containing N molecules of chemical A and another containing M molecules of chemical B, are mixed together at time t = 0. The molecules from the two chemicals combine to form another chemical solution containing y (AB) molecules. The rate at which the AB molecules are formed, 
, is called the reaction rate and is jointly proportional to
