The correct question is:
A circle has a radius of 45 units and is centered at (-2.4, -4.8).
What is the equation of this circle?
Answer:
Equation of the circle is;
(x + 2.4)² + (y + 4.8)² = 2304
Step-by-step explanation:
The standard equation of a circle is;
(x - a)² + (y - b)² = r²
where;
(a,b) is the center of the circle and r is the radius of the circle
Now, from the question, the circle is centered at (-2.4, -4.8) and the radius is 45
Thus, plugging those values into the standard form of equation of a circle, we have;
(x - (-2.4))² + (y - (-4.8))² = 48²
This gives;
(x + 2.4)² + (y + 4.8)² = 2304

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.
