Suppose u and v are functions of x that are differentiable at x=0 and that u(0)=5, u'(0)=-5, v(0)=8, and v'(0)=-2.find the values of the following derivatives at x=0

a)d/dx(uv)=?

b)d/dx(u/v)=?

c)d/dx(v/u)=?

d)d/dx(-6v-9u)=?

Varto company has 9,400 units of its sole product in inventory that it produced last year at a cost of $23 each. this year’s model is superior to last year’s, and the 9,400 units cannot be sold at last year’s regular selling price of $42 each. varto has two alternatives for these items: (1) they can be sold to a wholesaler for $8 each, or (2) they can be reworked at a cost of $251,100 and then sold for $34 each. prepare an analysis to determine whether varto should sell the products as is or rework them and then sell them.
