Suppose that the number of items sold after t months is
modelled by
500t
(25t + 2)²
a. Find N'(6) and N'(12).
b. Find N"(6), N"(12).
c. What do the answers in a. and b. tell you about N (t)?
N(t) =
Let f(x) = x+₁ and g(x) = √x. Let g(x) = √x and let
x-1
h(x) = fo g.
a. Find h'(x)
b. Find h'(4)
A company determines the cost, in thousands of dollars for
producing x items is given by C(x) = √500x²-x + 75.
Suppose that it plans to boost production in t months from
now according to the function x(t) = 30t + 7. Use implicit
differentiation to find how fast the cost will be rising 6 months
from now.
