What is the ellipse?
The equation for an ellipse is typically written as x² a² + y² b² = 1. x² a² + y² b² = 1. An ellipse with its origin at the center is defined by this equation. The ellipse is stretched further in both the horizontal and vertical directions if a > b, a > b, and if b > a, b > a, respectively.
The standard form of the equation of an ellipse with center (h, k)and major axis parallel to the x-axis is:
where,
a > b
the length of the major axis is 2a
the coordinates of the vertices are (h±a,k)
the length of the minor axis is 2b
the coordinates of the co-vertices are (h,k±b)
the coordinates of the foci are (h±c,k),
where c² = a² − b².
so,
Hence, this is the standard form equation .

Answer:
410.32
Step-by-step explanation:
Given that the initial quantity, Q= 6200
Decay rate, r = 5.5% per month
So, the value of quantity after 1 month,
The value of quantity after 2 months,
From equation (i)
The value of quantity after 3 months,
From equation (ii)
Similarly, the value of quantity after n months,
As 4 years = 48 months, so puttion n=48 to get the value of quantity after 4 years, we have,
Putting Q=6200 and r=5.5%=0.055, we have
Hence, the value of quantity after 4 years is 410.32.
