What is the difference b/w point A and B.
if the Equation is

-X^4+5x^3+4X^2+6X+8

Anyone know how to solve this problem, since I don't remember exact equation but the the answer was like 6 in, 4 in or 8 in.
There is no more information in the question, just one fig

I want to find all dimensions using calculus only volume is known.
I t was state exam question

Is it possible that
find L,W, H, if volume of rectangular prism is 500cm³,
I am trying to find this answer. calculus seems doesn't help. I am going to ask my teachers.

A right cylinder with radius r and height h. company wants to make a right cylindrical can that hold 500 cm³ of juice. assume thickness of the materical is negligible.
derive a function A(r) that represents the surface area of the can in terms of the radius,r, of its base.
show intercepts, extrema and asymptotic behavior of the function over the set of real numbers sketch graph.
state any restriction on the domain of the function so that it represents the physical model of the can.
find dimension of the can to the nearest tenth of cm.
find r=?
h=?
use differentiation
