Question 1: The capacitance between two parallel wires in space is given by the formula C = 1 / {3.6 ln [(d-r)/r] where d is the spacing between wire centers in centimeters, r is the wire radius in centimeters, and C is in picofarads per centimeter of wire length. Find the capacitance per meter of length for two 0.2-cm-rad

I am taking an advanced math course next semester that will involve using summation notation extensively and am somewhat anxious about it. Could you give me a primer on using Σ single, ΣΣ double, and triple sums with examples?

Use multiplication, division, addition and subtraction and at least one set of parentheses to write an expression that simplifies to 7, 13, or 17. Do your work step by step and explain each step as you simplify the expression. Demonstrate the consequences of not using the proper order of operations by showing that other orders

1. Find the flaw with the following "prof" that a^n = 1 for all non negative integers n, whenever a is a nonzero real number. Basis Step: a^0 = 1 is true by the definition of a^0. Inductive Step: Assume that a^j = 1 for all non negative integers j with j <= k. Then note that a^(k+1) = (a^k*a^k)/(a^k-1) = 1*1/1 = 1

Using mathematical induction, prove or disprove that all checkerboards of these shapes can be completely covered using right triominoes whenever n is a positive integer. a) 3 x 2^n b) 6 x 2^n c) 3^n x 3^n d) 6^n x 6^n

Can you please assist me with formulas for the following? 1. Formula needed for: A freight train leaves a station traveling at 32 km/h. Two hours later, a passenger train leaves the same station traveling in the same direction at 52 km/h. How long does it takes the passenger train to catch up to the freight train? 2. Desc

Hello, I need help with proving the following statement: "A prime p is said to be a Sophie Germain prime if n = 2p+1 is also prime. Prove that a prime p is a Sophie Germain prime if and only if 2^(n-1) = 1 (mod n)." Thank you for your time.

1. During a road trip, Tonya drove one-third the distance that Lana drove. Mark drove 15 miles more than Lana. The total distance they drove on the trip was 491. How many miles did each person drive? 2. A business wholesaler wants to create a new punch. He will mix fruit juice worth 2.00 per gallon and rum worth 7.00 per gall

Show that |(frac{f_(n+1)}{f_n}) - phi| = frac{1}{(f_n)(phi^{n+1})} and lim_{n --> infty} frac{f_{n+1}}{f_n} = phi, where phi is the Golden Ration and is the unique positive root of phi^2 - phi - 1 = 0. For some discussion on this question, see http://math.stackexchange.com/questions/106049/another-way-to-go-about-provin

Discuss the validity of each statement. If the statement is always true, explain why. If not, give a counter example. 1. Every polynomial function of odd degree is one-to-one. 2. The graph of a one-to-one function intersects each vertical line exactly once. 3. The inverse of f(x) = x^2 is g(x) = sqrt of x

Radium 226 gives half-life exponentially quantity of a metal with a half life of 1600 years, If you start with one kilogram of Radium how much will you have in 1000 years? How much after 10,000 years?

Use the approximation doubling formula (rule of 70) and discuss rather the formula is valid for the following case; "If oil consumption is increasing at a rate of 2.2 per year what is its doubling time? By what factor will oil consumption increase in a decade?"

Please assess this statement. A small town that grows exponentially can become a large city in just a few decades. Option 1) Does not make sense because exponential growth leads to repeated halvings, making the population decrease rapidly. Option 2) Does not make sense because growth cannot continue indefinitely so the
