    K-12 Homework Grades - Removal:Why or Why Not?

    There kids in high school already taking advance math and science courses so that's where I am comming from, high school algebra II for exa is pretty much the same as college algebra, concepts such as factoring a cubic polynomial doesn't change. Same with high school physics courses, problems...

    Finding Tangent Line to f(x) at (4, (2/5))

    I did that and I got something like 1/2*Sqrt(a) by taking the lim as h->0, giving a slope of 1/4, but the answer is sopposed to be y=(1/20)*x+(1/5) can you please show me how they got this ? By the way is that factor you posted called a conjugate ?

    Finding Tangent Line to f(x) at (4, (2/5))

    I need to find an equation for the tangent line to the graph of the function at the specified point, I had some trouble simplifing f(x) so that I can take the lim as h->0 which is the slope. f(x) = Sqrt(x)/5 at (4,(2/5))

    How can I accurately count milliseconds using clock_t start and stop in C?

    What about running the program in while booted dos mode, would it be accurate it that case ? How would I use a windows api with turboC, are there any other methods for counting microseconds in turboC ?

    Determine the velocity of an electron orbiting an atom ?

    Is it possible to determine the velocity of an electron orbiting an atom ? Would the velocity be greater for an atom with more mass ?

    How can I accurately count milliseconds using clock_t start and stop in C?

    Im using turboC so I don't have that fancy rtc.h library. What about counting how many seconds a longer {loop(containing var=var+1) while var<1,000,000} will take using clock_t and then... dividing by the number of seconds for the entire sequence by 1,000,000 to get the number of seconds it...

    How can I accurately count milliseconds using clock_t start and stop in C?

    In this program I am using I first declare clock_t start, stop then later position start and stop in a loop. To count how long a switch is turned on. The smallest value I see outputed is no lower than 0.05 sec but I want to be able to count miliseconds. printf("pulse length is %f seconds\n"...

    How Does the Law of Multiple Proportions Apply to Sulfur and Fluorine Compounds?

    Sulfur forms two compounds with fluorine. In one of them it is observed that 0.447 g of sulfur is combined with 1.06 g of fluorine while in the other, 0.438 g of sulfur is combined with 1.56 g of fluorine. Show that these data illustrate the law of multiple proportions. would...
