Is there any reason why it equals Zero

Is this correct? 1. Find the height of a cylinder whose radius is 2 cm and whose volume is 1.00 cm^3. V = pi*r^2*h h = V/(pi*r^2) = 1/ h = 0.0796 cm The graduations would be 0.0796 cm apart 2. Find the height of a cylinder of radius 2 which has a volume equal to that of the sphere...

A certain graduated cylinder has an inside diameter of 4cm. The graduations on its side are labeled "cc" (cubic centimeters). 1. How far apart are these graduations? 2. The cylinder is partially filled with water, and a solid sphere of radius 1.2 cm is then totally submerged therein...

I used archimedes and solved it.

Homework Statement Once upon a time the famous archimedes was given a problem to determine if a crown supposedly made of pure gold actually contained some silver. If Archimedes was your lab partner, explain how the two of you could quickly determine if the crown were gold or not without...

It is said that mean deviation does not take into account algebraic signs of deviations. What if we take into account the algebraic signs of the deviations. Will there be any difference. Which will be more accurate and why does the mean deviation use the absolute values of the deviations, why...

I got -0.0005 when I tried calculating it with these set of deviations: .003, .005, -.005, -.009, -.011, .015, .000, -.011, -.009, -.001, .001, .016, -.005, -.020, -.002, .019, .001, .009, .006, .001. With a mean of .760.

Usually when solving for the average deviation, we have to sum up the ABSOLUTE values of individual deviations. What happens when we simply summed the individual deviations (negative and positive) for a large set of measurements.

Just plotted the graph

Thanks. Just realized I have been looking at the question the wrong way

Actually, ln n < n^{1/10} is only true for n < 3 (for integer values of n).

Homework Statement Explain why the Direct Comparison Test allows us to use the inequality Ln n < n^(1/10) even though it is not true for a great many n values. Homework Equations The Attempt at a Solution I looked at the graphs of Ln (n) vs. n^(k)

Yeah, finally solve it. I used the inverses and reflection of the two graphs at x=y.

Homework Statement give a general rule for when Integral (1/x^n) from (x, 0, a), a>0 converges or diverges. Homework Equations The Attempt at a Solution I have checked the textbooks for this answer but i can't seem to find it. The closest i got was Integral (1/x^n) from (x, 1...
