9. The decimal number above consists of only 1's and 0's to the right of the decimal point. The first 1 is followed by one 0, the second 1 is followed by two 0's, the third 1 is followed by three 0's, and so on. What is the total number of 0's between the 98th and 101st 1 in this decimal number? (A) 288 (B) 291 (C) 294 (D) 297 (E) 300 10. If \[f(x) = \frac{3 - 2x^2}{x}\] for all nonzero \[x\], then \[f(2) =\] (A) \[\frac{11}{2}\] (B) \[\frac{7}{2}\] (C) \[- \frac{1}{2}\] (D) \[- \frac{5}{2}\] (E) \[- 7\]  11. In the figure above, \[\ell \bot n\] and \[x > 90\]. Which of following must be true?
(A) \[y < 90\] (B) \[y > 90\] (C) \[y = 90\] (D) \[n \bot m\] (E) \[\ell || m\] 12. In the \[xy\]-plane, the line with equation \[y = 5x - 10\] crosses the \[x\]-axis at the point with coordinates \[(a, b)\]. What is the value of \[a\]? (A) -10 (B) -2 (C) 0 (D) 2 (E) 5
