Question 10 The equation of the normal line to the function f (x) = _ at (2, ) at the indicated point is O aly = 36 ( xx - 2) + Obly = - 36 (x - 2) + Ocly = 36 (x - 2) + 3 O d) y = 36 (x - 2) + 7 ( ely = 16(x - 2) + Ofly = - 16 ( x - 2) + 6 O g) None of the aboveQuestion 11 The rate of change of f (x) = 2x 2 2x+6 at x = 1 is a) lim 8x2-4x-14 x-1 8(x - 1)(2x+6) b) lim 8x2-4x-12 x-18(x + 1)(2x+6) O c) lim 8x- -2x-6 x-1 4(x - 1)(2x+6) O d) lim 8x2-2x-12 x-1 8(x - 1)(2x+6) O e) None of the aboveQuestion 12 The volume Vof a tumor can be approximated by V(r) = a r3 where ris the radius of the tumor, in centimeters. The rate of change of the volume at r = 1.3 cm is: Note: For consistence in the calculations, round up the final number (the answer} of the calculations so if you get 2.0456 it will be 3 and if you will get 2.8912 it will be 3.
