If $15,000 is invested at 6.5% annual interest compounded annually, how long would it take for the account balance to reach $50,000? Round your answer to the nearest tenth. RATIONALE To find the answer, use the formula for compound interest and solve for t: where: A = 50,000 P = 15,000 r = 6.5% or 0.065 n = 1 To begin, substitute the known values and simplify the formula first by adding the values in the parentheses and dividing both sides by the coefficient. To undo the variable expo...

Differential Equations Exam Questions and Answers What is a differential equation? - Answer-An equation which relates several quantities and their (1st, 2nd, 3rd, etc) derivatives y' = 0. What is the rate of change of y? What are the solution(s)? - Answer-Nothing. Y is a constant quantity. The solutions are y(x) = C, where C is a constant. y' = x. Solution(s)? - Answer-dy/dx = x, so y(x) = 1/2(xˆ2) + C y = 2x + [cos(xˆ2)]. Solution(s)? - Answer-sinxˆ2 + C dy/dx = y. Solution(s...
