The size of a certain population of reindeer in Richmond County varies according to a sinusoidal model because of certain ecological pressures. In 1990 the population was at the maximum of 600 and in 1994 it was at the minimum of 480.
a) Sketch the sinusoidal curve that models this situation. b) Determine the sinusoidal model equation that models the deer population in terms of years starting with 1990. c) use your model to predict the current deer population ( 2020 )

none cuz there are no "following statements" regarding the question

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
