  1. f(x) = 1/x ----> f '(x) = -1/x^2 1/99 is approximately 1/100 so close to this the gradient of the tangent is -1...approx= 1/100 + 0.0001 = 0.0101 Edit. A calculator will of course confirm that 1/99 = 0.010101010101.......

  2. ...to pick from and we need to pick 6.... also with a lottery order of numbers does not matter. 99!/(6!*(99-6)!) will give us our answer = 99*98*97*96*95...

  3. ...does not have cancer, so 1% of 99.8% = 0.998% ≈ 1% 2. prob( not L) we did in 1, 99.8%. by the way, you lose a lot of accuracy if you round off your...

  4. What are you doing with 49+49+1? It doesn't make sense to do that, let alone expecting it to equal 100. It should be 49 + 49 − 1 = 97. Anyway, if you don't have money, then don't buy the shirt.

  8. the infinite series 9/10 + 9/100 + 9/1000 ..... = 0.999.... does equal 1. let S = 0.9999.......... then 10S = 9.99999.......... subtract the equations 9S = 9.00000........ S = 1

  9. ..., then this is a really stupid question. f(x) = -0.125 at x = 2, but that does not guarantee that f(x) will be anywhere near -0.125 for close values of x = 2...
