Answer: see below
<u>Step-by-step explanation:</u>
The coordinates on the Unit Circle are (cos, sin). Since we are focused on cosine, we only need to focus on the left side of the coordinate. The cosine value (left side) will be the y-value of the function y = cos x
Use the quadrangles (angles on the axes) to represent the x-values of the function y = cos x.
Quadrangles are: 0°, 90°, 180°, 270°, 360° <em>(360° = 0°)</em>
Together, the coordinates will be as follow:
Answer:
49243
Step-by-step explanation:
Given that the population of rabbits on an island is growing exponentially.
Let the population,
where, and b are constants, t=(Current year -1994) is the time in years from 1994.
In 1994, t=0, the population of rabbit, P=9600, so
So,
and in 2000, t=2000-1994=6 years and population of the rabbit, P=18400
b=0.109
On putting the value of P_0 and b, the population of the rabbit after t years from 1994 is
In 2009, t= 2009-1994=15 years,
So, the population of the rabbit in 2009
Hence, the population of the rabbit in 2009 is 49243.
