Homework Statement
Dear All,
I currently have a set of data which, when plotted on a scatter diagram, proves an inverse proportionality between two sets of data. (Please see attachment.)
I now need to linearize the graph as to estimate the half-life of the foam.

I'd have another question, always on the same type of problem.
A girl approaches a tower 75m high at 5km/hr. At what rate is the distance from the top of the tower changing when she is 50m from the foot of the tower?
What is given is:
\frac{dX}{dt} = 5km/hr )
Where X is the...
So L(5) is 12.5. Therefore I should now substitute values in the equation for \frac{dV}{dt}, but doing so returns a wrong answer according to my textbook...
Dear Mark44, thanks for your answer.
I'm sorry, I always mistake terminology and syntax. What I meant is that the length of the sides at time T is 10 (original size) + 0.5 (expansion/hour) * T (number of hours): 10+0.5(T)... Is this correct?
Homework Statement
Dear All,
I am having problems understanding how to deal with related rates. The problem is the following:
A solid 400gm metal cube of size length 10cm expands uniformly when heated. If the length of its side expand at 0.5cm(hr), find the rate at which, after 5...

My books states, considering a stationary source emitting waves at frequency f, such waves having velocity v, and an observer approaching the source along a linear path at velocity vO we have that: The observer registers the velocity of the waves at v+v0. Up until now all...
Homework Statement
Find the first derivate of \frac{2}{x+1}.
Formula: \frac{f(x+h)-f(x)}{h}
Homework Equations
Formula: \frac{f(x+h)-f(x)}{h}
The Attempt at a Solution
\frac{\frac{2}{x+h+1}-\frac{2}{x+1}}{h}
h(\frac{2}{x+h+1}-\frac{2}{x+1})
h(\frac{2(x+1)-2(x+h+1)}{(x+1)(x+h+1)}...
Homework Statement
Dear All,
I would like to ask you a question as the concept doesn't seem to be best explained on my book.
It is stated that during non-cyclic phosphorylation two electrons (One per molecule of Chlorophyll in the reaction center.) leave PSI, travel an electron transport...
