36 SECTION-E In drilling world's deepest hole, the Kola Supendeep Horebole, the deepest anime hole on Earth and deepest artificial post on Earth, as a result of a scientific drilling project, it was found that the temperature T in degree Celsus, x kan below (1-1-2) the surface of Earth, was given by 30+25 (x-3), 3<x<15 If the required temperature lies between 200°C and 300° C, then The depth, x will lie between a) 9 km and 13 km b) 9.8 km and 13.8 km c) 9.5 km and 13.5 km d) 10 km and 14 kms Solve for x: -9x+218 OR 13x+155-4 a) XS-1913 b) x-1613 c) -1613-x-1913 d) There are no solution Graph the following inequality on the number line: x>-32 b) + d) OR Find the inequality represented by the graph below a) y ≤ 12x+2 b) y > 12x+2 c) y ≥ 12x+2 d) y < 12x+2 37 The function 'T' which maps temperature in degree Celsius into temperature in degree Fahrenheit is defined by t(C)- +32. Answer the following questions based on the above information Find t(-10) ti. Find t (28) (1+1+2)
