Consider the autonomous system for r E R": i(t) = f(x(t))

Let r>0 be some fixed constant, and let D = {r: xSr}. =

(1)

Suppose there exists a continuously differentiable function V, defined on D such that Vi(0) = 0 and V is positive definite along solutions of Equation (1). Furthermore, suppose for anyeE (0. r), Vi itself is not negative semidefinite on {r: |<e},

Prove that the origin is unstable.​

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
