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 )

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8

fo there supposed to be answer choices there
