Calculus
Given a right circular cone, you put an upside-down cone inside it so that its vertex is at the center of the base of the larger cone, and its base is parallel to the base of the larger cone. If you choose the upside-down cone to have the largest possible volume, what fraction...

Calculus (Optimization)
Both of you, thank you very much!!! I arrived at the correct answer width = 18 and length = 36, but I just got that answer by chance and wasn't sure how I could prove (mathematically) that it was indeed correct, your explanations helped tremendously!

Calculus (Optimization)
The U.S. Post Office will accept a box for shipment only if the sum of the length and girth (distance around) is at most 108 inches. Find the dimensions of the largest acceptable box with square ends.

Physics (Really need help with this)
An astronaut lands on an alien planet. He places a pendulum (L = 0.200 m) on the surface and sets it in simple harmonic motion. a. What is the period and frequency of the pendulum’s motion? b. How many seconds out of phase with the displacements shown would graphs of the ...

Calculus
True or False: Consider the following statement: A differentiable function must have a relative minimum between any two relative maxima. Think about the First Derivative Test and decide if the statement is true or false. I want to say that its true and that the question is jus...

Calculus
Nevermind, I figured it out. Since the function is odd it must be symmetric about the origin, so: concave up: -5 < x < -3 and 0 < x < 3 and x > 5 concave down: x < -5 and -3 < x < 0 and 3 < x < 5

Calculus
Suppose you know that f(x) is an odd functon on the domain of all real numbers and that the function is concave up on the intervals 0 < x < 3 and 5 < x and concave down on the interval 3 < x < 5. List ALL intervals on which the functon f(x) is concave up and ALL...

I would just like to know if these sentences are grammatically sound. Esta es la receta para empanadas de pera de Chile. Estos son los ingredientes: Dos tazas de peras secas Dos tazas de agua Tres cuartos tazas de azucar Una cucharilla de canela Una cucharilla de clavo Dos taz...

Calculus (Continuity and Differentiability)
I think that I may have confused you about the graph that I am dealing with. I know that if a corner is present in an original function, then it will not be differentiable at that point. I thoroughly understand this point. Now, the graph that I am given is the graph of the der...
