1.) Two volumes of an encyclopedia stand side by side, in order, on a shelf. A bookworm starts at page i of Volume I and bores its way in a straight line to the last page of Volume II. Each cover is 1 mm thick, and the first volume is 2/5 as thick as the second volume. The first volume is 40 mm...

This is not a homework question but a general doubt. Suppose we have a function y = pcosx, where 'p' is an arbitrary constant. So my question is how will the graph of this function change with different values of 'p'? This doubt can also be extended for other functions like y = pex, y = p...

Hey! :o We have the following graph: I want to find a minimal vertex cover. I thought that the set $C^\star=\{4,5,6\}$ is a minimal vertx cover. Is this correct? How could we prove it? (Wondering) Then I want to find a vertex cover using the following approximation algorithm C <- 0 while...

OK, so a LONG time ago I believe I saw a small drawing by Newton which represented the first true drawing of a Cartesian graph with an x and y-axis and "O" at the origin. Now (that I'm old and can't remember what I had for breakfast) I'd like to find it but can't remember where it was. Any help...

Homework Statement Homework EquationsThe Attempt at a Solution I chose C as if a strong "something" is added to a weak "something" then you won't get a strong curve. So acetic acid will be eliminated. If D or E was added, the equivalence point should have pH of 7 or less. Therefore I chose...

Hello! I'm completing my IB Physics IA and after collecting my data and plotting the raw graph my graph seems to be a negative parabola. In order to linearize it I though one had to square the x-axis data; however I simply get the same graph shape. What am I supposed to do? Only when I plot the...

Question (and Answer): The answer is written in thin black, inc = increasing, dec = decreasing. Am I wrong anywhere? Thanks!

Are there any theorems that say something formal about the fact that any graph is drawable on a 2D surface, and can be mapped to a 2D array of pixels if the pixels are infinitely small?

I have read in many places that one necessary condition for the existence of a Euler circuit in a directed graph is as follows. Theorem: "A directed graph has an eulerian circuit if and only if it is connected and each vertex has the same in-degree as out-degree." However, I don't understand...

I graphed different heights from which I had dropped a bouncing rubber ball on the y-axis and the time taken for it to bounce on the x-axis. The function came out to be quadratic, but I do not know why. If someone can show mathematically why this is, that'd be splendid. Thank you.

I oscillated a spring attached to a force sensor above a position sensor. The position and force sensors were zeroed at the spring's equilibrium. The graph below was my result.
