Mathematics A indecision One A reck integrityr virus has started to vitiate computers around the realism. The virus started from just one computer and is banquet at a rate of 28% per hour, if the virus ashes uninterrupted. a) How many computers will it harbor spoiled by the end of the day? P = 1i = 0.28or 28% t =24 hours FV= P (1+i) t FV = 1 (1+ 0.28) 24 FV= 1 (1.28) 24 FV? 378.14 Based on the above, the virus would cloud close to 378 computers by the end of the day. b) How many will it have infected by the end of the second day? P = 1i = 0.28 or 28% t = 2x14 hours FV= P (1+i) t FV= 1 (1+ 0.28) 2x24 FV = 1 (1.28) 48 FV ? 1 x 139 984.05 FV ? 139 984.05 Based on the record above, by the end of the second day the virus would have infected approximately 139 984 computers. c) How long will it take to infect the worlds 5000 000 000 computers? FV = 5 000 000 000P = 1i = 0.28or 28% t =? FV = P (1+i)t 5 000 000 000 = 1 (1+0.28)t 5 000 000 000 = 1 (1.28)t 5 000 000 000 ÷ 1 = (1.28)t (1.28)10? 11.8059 (1.28)50? 229349 (1.28)80? 377 396 242.5 (1.28)85? 129 672 3615 (1.28)90? 4 455 508 416 (1.28)91? 5 703 050 772 (1.28)90.25? 4 739 142 425 (1.28)90.47? 5 003 638 829 90.47 ÷ 24 =3.769 long time 0.769x24 ?18.46 hours Therefore, based on the march above it would take approximately 3 days 18 hours and 46 minutes to infect the 5 000 000 000 computers in the world.
