Question

In the past, the number of fish in a pond could be modelled by the function P(1) - 7000 - 2000 sin where is the number of months after January. However, because of a lack of fishermen since the start of the new year, the number of fish in the pond has been increasing at a rate of 35 per month. If this pattern continues, which of these functions could now be used to model the number of fish in the pond? R(!) - 7000 + 35t - 2000 sin R(1) - 7000 - 2000 sin (1 + 35) a. c. b. d. R(!) - 7000 - 2035 sin R(1) - 7035 - 2000 sin

Answer 1

ANSWER:-

Given that Since the number of fish is incaeasing ata oratect 35 per month, so the terms 35th aumbet should be present in any model of the number of fish in the pond, where t is the number of months after janunary Hence, the model pro which the team 35€ Pas missing Cannot be considered as a proper model of the number of fish in the pond. So, PCt), en (b), (c), (d) all of the could not be need to model the number of fish in the pond. only (a) can be used as a proper model.
