a city in Africa, an epidemic spreads during 50 weeks according to the model of a sinusoidal function from the moment we observe that 8400 people are infected. Twelve weeks later, the maximum number of people infected recorded is 12 600. At the 36th week of the epidemic, the minimum number of people infected recorded 5 4200. Number of people Infected 12 600 8 400 4 200 y 0 3 Number of weeks Determine, within the 50 weeks that the epidemic spread, the number of weeks where the number of people infected was less than or equal to 6300.
