I have recently just been given a computer lab task and that is to research transformations on the net and write a 1 page essay about them, which i am finding hard to find information on them, but anyway, here is my problem. We are required using our classes data to do transformations of our...

thankyou for both of your help, it was greatly appreciated.

I have just started at university and i have a couple of the questions that i could not fill out during my laboratory. Lab 1, Acids and Bases 1. Describe a simple chemical test to distinguish between a solid sodium carbonate and solid sodium chloride. My thoughts on this was to react them...

I have just started University and we have been doing t-tests however in our Computer labs we are supposed to do the Levenes Test. I have done the levenes test from our data of males and female heights in our class. i was just wondering what a value of F = 0.001 and Sig. 0.982 would mean. the...

Question 8 - From your results above, which would be the best estimate of the true mean height (170.18cm) of the population of Bioinformatics students? Explain! I am having a little trouble on this question and what exactly is it. It is asking me for which would be the best estimate of...

I have just started electricity in physics and am wondering how to do this homework questions. The question is: Sphere A and B are insulated metal spheres with charges of +10 micro C and -5 micro C respectively. If sphere A has twice the radius of sphere B, what will be the charge on each...

cheers people, thanks for that

This is probably an easy question for most of you, but me nor my teacher knew. Today we learned that nuclear fission can occur when a neutron "hits" the nucleus of Uranium-235. What i wanted to know is, where does this neutron come from, and how can they make it hit this uranium-235 atom. Any...

We have this complex reasoning question (at school) with this weird situation, anyway they say incorporating every part gives the formula V = mgR tan (\theta) / B^2 L^2 cos (\theta) Where V is the velocity m is the mass g is the acceleration (gravity) B is the magnetic field strength...

As part of a homework assignment, I am required to research Newton's Law of Cooling and evaluate it with three practical examples. One must be time of death. So far i have created a time of death example, and used an example to cool food. However the last one i heard someone say is that you...

Im having a bit of trouble using Newton's Law of cooling. I have been given the formula T(t)=T_s + (T_0 - T_s) e^{-kt} . I am trying to find the time of death of a body, and I am given the time the body was found 12.00pm, its temp around 90, 2nd check, at around 1.00pm, temp is 80, and the...

thanks for your responses everybody. A few people in my class like me complained about this problem aswell. The lowdown is, i am now given the graph (has those points i put in here before) and using transformations, eg. compressing, translating and stretching, manipulate log (x) by adding...

sorry, its just I am in year 12 and we haven't learned it, that's why its a homework assignment, we go home and find out bout stuff we never learned before

ok, well i haven't done polynomials yet so i would absolutely no idea.

well we haven't been taught anything about transformations, and we have to find it all ourselves. The graph is flipped compared to the normal log graph (ie when a is a negative number.
