4. An erroneous proof of a statement is given below. Indicate where a fundamental error in the argument is made. Briefly explain what the error is. The statement is false but this is not relevant to your answer. The lines of the proof have been labelled to make it easier for you to answer. [2 marks] Statement: Let a and b be positive real numbers. If b > 5, then log, (250) <3. Proof: (1) Let a, b e R where a, b > 0. (2) Assume b>5. (3) Using rules of logarithms, log(250) = logo 25+ logo a. (4) Since b > 5, then log, 25 = logo 52 <2. (5) When a = b, log, a = 1. (6) Therefore logo (25a) < 2+1 = 3.

PROBLEM 05: Each time any student in an M118 class tries to log onto Webwork, there is a 43% chance that the Webwork system will be inaccessible. If a total of 500 students try (once each) to log onto Webwork during a week, how many of them should we expect to be able to log on successfully? A) 215 B) 285 C) 212 D) 288 E) 126 N) none of the above

1. (a) State the precise mathematical definition of lim f(0) = -0. (b) If B(h) is the barometric pressure in kiloPascals at height h in kilometers. What is the physical interpretation of B'(2) = 1? (c) Write the definition of tanh c and state its domain and codomain. (d) Find the exact value of log (2) – log (5) + log2 (20). (e) Use the Intermediate Value Theorem to prove that the function f(c) = r4 - 2r3 – 3.r+2 has at least one real root.
