I can answer all questions up to, and including, graduate level mathematics. I am more likely to prefer questions beyond the level of calculus. I can answer any questions, from basic elementary number theory like how to prove the first three digits of powers of 2 repeat (they do, with period 100, starting at 8), all the way to advanced mathematics like proving Egorov's theorem or finding phase transitions in random networks.

I can provide good answers to questions dealing in almost all of mathematics especially from A`Level downwards. I can as well help a good deal in Physics with most emphasis directed towards mechanics.

I can answer any questions from the standard four semester Calulus sequence. Derivatives, partial derivatives, chain rule, single and multiple integrals, change of variable, sequences and series, vector integration (Green`s Theorem, Stokes, and Gauss) and applications. PreCalculus, Linear Algebra and Finite Math questions are also welcome.

I can answer any question in general math, arithetic, discret math, algebra, box problems, geometry, filling a tank with water, trigonometry, precalculus, linear algebra, complex mathematics, probability, statistics, and most of anything else that relates to math. I can also say that I broke 5 minutes for a mile, which is over 12 mph, but is that relevant?

I can answer questions in Algebra, Basic Math, Calculus, Differential Equations, Geometry, Number Theory, and Word Problems. I would not feel comfortable answering questions in Probability and Statistics or Topology because I have not studied these in depth. 
Noting that 3 times 2 = 6, write log10(6) = log10(3･2) = log10(3) + log10(2) = a +b < a and b are known using the algebraic property of logs. Also, for the unknown x log5(6) = x >
Hi Michelle, f(x) = x³ + Ax² + Bx  15 f'(x) = 3x² + 2Ax + B f''(x) = 6x + 2A For a maximum point the first derivative f'(x) is zero and the second derivative f''(x) is positive. So, at x = 2 3(2)²
Kilograms (kg) to grams (g) is an easy conversion. We have by definition, 1 kg = 1000 g = 10^3 g. Using scientific notation on the number you provided, the mass of the earth in kilograms is 5537831004648121688015772
It all depends upon whether or not the person answering the phone remembers hearing the old voice. Very rarely it happens that someone heard sounds like someone else. There are a few professional people
Of course  they could be operated just like the lamps and be turned on at night. To turn them on, a spark could be sent from a nearby system similar to the one that turns on a street light at night.
